Analysis and Design of Multistoried Building Subjected yo Dynamic Loading
(2018-06-22T08:43:32Z) Pavan, V; Prajwal, P; Prathik S, Reddy; Ramesh, DNP
Recommendations provided by seismic codes help the designer to improve the behaviour of structures so that they may withstand the earthquake effects without significant loss. Seismic codes are unique to a particular region or Country. They take into the account the local seismology, accepted level of seismic risk, properties of available materials, methods used in the field of earthquake engineering and property. Most of the recommendations of IS codes are based on observations during past earthquakes as well as experimental and analytical studies made by scientists, engineers and seismologists. In India, the 1st seismic code namely IS 1893 was published in 1962. Seismic analysis and design for this project will be in compliance with IS 456/IS 1893, The concept of earthquake resistant design is that the building should be designed to resist the forces which arises due to design basis earthquakes, with only minor damages and the forces, which arises due to maximum considered earthquakes with some accepted structural damages but no collapse. The design philosophy was established considering the following aspects: The structure should withstand the moderate earthquakes, which may be expected to occur during the service life of structure with damage within acceptable limits. Such earthquakes are characterized as design basis earthquakes. The structure should not collapse when subjected to severe ground motion that could possibly occur at the field. Such earthquake is characterized as maximum considered earthquakes. Buildings are designed as per Design based earthquake, but the actual forces acting on the structure is more than the design earthquake. So, in higher seismic zones Ductility based design approach is preferred as ductility of the structure narrows the gap. The primary objective in designing an earthquake resistant structure is to ensure that the building has enough ductility to withstand the earthquake load.

Due to scarcity of petroleum and coal it threatens supply of fuel throughout the world also problem of their combustion led to research in different corners to get access the new sources of energy, like renewable energy resources. Solar energy, wind energy, different thermal and hydro sources of energy, biogas are all renewable energy resources. But, biogas is distinct from other renewable energies because of its characteristics of using, controlling and collecting organic wastes and at the same time producing fertilizer and water for use in agricultural irrigation. Biogas does not have any geographical limitations nor does it requires advanced technology for producing energy, also it is very simple to use and apply
Biogas Production from Anaerobic Digestion using Sewage Sludge
(2018-06-21T07:59:43Z) Adel, Jeelani; Khalid, Ajaz; Kumar, Shivankar; R K, Pintu
Biogas production requires anaerobic digestion. The anaerobic digestion of kitchen waste produces biogas, a valuable energy resource. Anaerobic digestion is a microbial process for production of biogas, which consists of primarily methane (CH4) & carbon dioxide (CO2). It is further facilitated by addition ofinoculum i.e. sewage sludge. The wastes produced in the college premises is dumped which is not utilized and proves to be a nuisance to the environment. Hence this waste was used for biogas generation. Preparations were for the installation setup where the generation of biogas was measured and different laboratory tests were carried out. The continuously-fed digester requires addition of sodium hydroxide (NaOH) to maintain the alkalinity and pH to 7. The digester was seen to have a temperature of 30°C mesophilic range

(2018-06-22T09:18:43Z) Sumith, B N; Prashanth, G M; Sangamesh
In the seismic design of a multi storey building To ensure the stability against the lateral force caused by earth quake various methods are used, the most commonly used method is provision of shear wall to the building. The reinforcement concrete shear wall is the most reliable method of construction of shear wall which make the structure resistant against lateral forces, as it imparts stiffness to the structure and provides enough strength which minimises the damages caused by the earthquake. In this paper three models are analysed one without shear wall and two with shear wall at different location, one at the corner and one with shear wall at the faces and core of the building through STAAD Pro. Equivalent static method is used for software validation and response spectrum method is used for comparison of three models

Comparative Study on Structural Parameter of RCC and Composite Structures
(2018-06-21T06:44:39Z) Basavaraj S, Bachihal; C M Lakshmi Narayana, Kanth; Hemanth, D R; Lakshman, K
In today's modern era of innovation, two materials widely and inevitably used as construction material are steel and concrete for structures ranging from buildings to bridges. Though these materials may have different properties and characteristics, they both seem to complement each other in many ways. Steel has excellent resistance to tensile loading but lesser weight ratio so thin sections are used which may be prone to buckling phenomenon. On the other hand concrete is good in resistance to compressive force. Steel may be used to induce ductility an important criteria for tall building, while corrosion protection and thermal insulation can be done by concrete. Similarly buckling of steel can also be restrained by concrete. In order, to derive the optimum benefits from both materials composite construction is widely preferred

(2018-06-21T07:07:56Z) Adarsh, L D; Madhu Patel, N V; Manoj, R; Shivanand, Patil
In order to meet the performance requirements of the concrete for various infrastructure projects, concrete mixers have to be designed and produced using combinations of different cementitious materials with water and aggregate and chemical admixtures. The active constituent of concrete is cement paste and largely it determines the performance of the cement paste, also setting time acceleration or retardation can be achieved by the use of admixtures. In addition of some particular admixture may develop undesirable interaction between varying ingredients of concrete. Many times addition of admixture beyond the certain limit may show incompatibility. The constituent materials of making concrete confirm to Indian standard specifications, but different types of cement vary from batch to batch and brand to brand in there chemical composition. Therefore in this study the compatibility of a chosen admixtures (Auromix 200, Master Glenium sky 8341, Master Rheobuild 1126 N D and Master Glenium sky 8233) with different brands of 53 grade ordinary Portland cement ( ACC cement, Birla Super cement, Dalian cement, Ramco cement and Maha cement ) have been determined by optimum dosage and efficiency of admixtures by marsh cone test.

Out of the various determinants that lead to success a project, construction management plays vital role among them. Delay in project would cause wastage resources and money needs be analyzed. The methodology adopted has direct impact on strength quality structure. In this aspect, precast concrete is considered produce better productivity reduce completion time, cost dependency work force. This reviews summarizes cost, system order compare with conventional. The present-day world is witnessing the construction of very challenging and difficult structural engineering works. The concept and approach towards the analysis of design of structures is totally redefined with the application of new structural aid software’s such as Etabs and STAAD. The time affective and economic advantages of this software’s are distinct from conventional and manual methods of analysis and design. In the current project titled “Design and Analysis of Multi-story residential building using STAAD”. A sincere attempt is made to design a multi-story residential building using STAAD and by doing so an attempt is made to understand the behavior of the building as a whole rather than the behavior of the individual structural member. The main objective of this project is to design multi-storey building (G+4) using pre-cast method and conventional method. Software used in this project are AutoCAD for planning and drafting, STAAD Pro for analysing, designing and check, Excel for result which will be produced in excel sheet. In the developing county, this project has higher market value as to carry out manually calculation of each component slab, beam and columns is difficult and time consuming & by using high efficient software we can reduce design time and complete project in early time. In construction and real state, time is money which results in saving large amount of money.

(2018-06-21T09:00:57Z) Amrutha Lakshmi, B.M; Apoorva.M., Reddy; Charan, .R; Darshini.P., Naik
Since globalization, day by day construction activities have enormously taken place. The raw materials used for making concrete have become an acute shortage, especially aggregates. In the present study, we have made an attempt to replace natural crushed coarse aggregate by cinders, which is a by-product of steel manufacturing industry in slag based concrete blocks. Blocks of size 400*200*150mm are chosen and mix proportion is selected as per IS: 2185 i.e., 1:4:8 and w/c is 0.6. The blocks were casted by replacing (0%,20%,40%,60%,80%, & 100%) natural crushed coarse aggregate by cinders using concrete block making machine (egg laying machine), and cured for 28 days. After curing, the blocks were tested to know the mechanical properties such as compressive strength, modulus of elasticity and water absorption. From the results obtained, 20% replacement is found to be suitable in terms of strength development, water absorption and modulus of elasticity.

(2018-06-22T08:52:50Z) Srinivas, N; Prashanth, Kumar K; Rajakumar, A M; Swati M, Patil
The main objective of this research is to investigate the possibility of utilizing waste steel slag in concrete production. In this project experimental investigation conducted on optimum steel slag replacement with coarse aggregate. After the formation of by-product steel slag, in large amount from steel industries. This steel slag is disposed to open land area, it makes land pollution and harmful to environment. It has good physical parameters and gives enough strength to concrete and due to this it is suitable to bear heavy load. In further study coarse aggregate is replaced by steel slag, and then concrete is prepared. The replacement ratio which have been studied were, 20%, 40%, 60%, 80%, and 100% by weight. Water–cement ratio kept 0.42. Concrete made with steel slag as coarse aggregate replaced achieved better performance compared to normal concrete. Physical properties of conventional concrete and coarse aggregate replaced concrete are compared. On fresh concrete slump test was preformed to check workability of concrete and after then compressive strength and split tensile strength was checked. Thus steel slag is appropriate substitute of coarse aggregate in concrete mix for construction.
Experimental Investigation of Fiber Reinforced Concrete Using Different Types of Steel Fibers
(2018-06-21T09:44:10Z) Bhavyashri, R; Deepika, B G; Gangamma, K; Vanitha, B
Concrete is strong in compression but weak in tension. As concrete is brittle material the failure in concrete due to tension is sudden. There are also cracks in concrete due to shrinkage and these micro cracks propagate and leads to failure. To safeguard the concrete against flexural cracks fibers are used in concrete section which is known as fiber reinforced concrete
Fibre Reinforced Self Compacting Concrete
(2018-06-22T09:01:15Z) Shivshankar; Rakesh, S; Raju, Angadi; Virupaksha
The concept of self compacting concrete (SCC) was proposed by prof. okamura at Tokyo. He gave the first prototype by using materials existing in the market. The SSC has now took with enthusiasm across the world in both site and precast work. Practical application has been determined by research on physical and mechanical properties of SCC. Earlier SCC consist of more cementitious paste, the mix required well specialized and controlled placing method to avoid segregation, but the higher cement paste made the better shrinkage and more heat generation. The basic principle is that it gets compacted by its own weight without entrapped air completely while flowing in the formwork. In higher reinforced structural member, it fills all the voids and gaps to maintain concrete as horizontal level when it is placed. Along with its composition, it consist of similar components like as conventionally vibrated normal concrete that is cement, aggregates, water, admixture. Due to use of more dosage of plasticizer or super-plasticizer leads to reduction in the liquid limit and giving better workability, more the powder content as lubricant for the coarse aggregates. Using viscocity modifying agent will increase the viscocity of concrete for better handling.

Hybrid Fiber Reinforced Concrete with the addition ofStyrene Butadiene Rubber (SBR) Polymer -An Experimental Study
(2018-06-22T09:29:49Z) Gajendra, R; Varun; Ravi Kumar, Reddy; Anush, BS
Fibre Reinforced concrete is a well-known composite material used in civil engineering and other applications. Conventional concrete has poor tensile strength so its capacity to absorb Energy is limited. The weakness in tension zone can be overcome by strengthening their matrix with reinforcing fibrous materials. Presence of fibres in concrete mix improves tensile strength, flexural strength and structural quality of the material as well. At the same time it is well known that the concrete is porous and the porosity is due to water-voids, air voids or due to inherent porosity of gel structures itself and the strength of the concrete is naturally reduced. It is investigated and conceived by many research workers that dropping of porosity results in improvement in the strength of concrete. The addition of monomer (Styrene Butadiene) and consequent polymerization is the modern practice adopted to decrease the present porosity of the concrete and to improve the strength. The present study is done on the mechanical behaviour of hybrid fibre reinforced polymer concrete. Experimentation includes compression strength test, flexural strength and split tensile strength test for M30 grade concrete mix, where concrete was reinforced with 2% fibres with combinations of Crimped fibres + Hooked End steel fibres, To this combination SBR polymer was added in 0, 5, 10, 15, 20 and 25 percentages by the volume of water and strengths were found out. The results indicated that as the polymer content increased to up to 15% showed that strength and workability also increased and decreases beyond all. There was a considerable increase in compressive strength, but there was a great strength achievement in tensile strength and flexural strength for 15% polymer content.
