Comparative Study of R.C.C. and Composite Structures Under Different Soil Conditions

Abstract

Abstract: The need for multi-storey buildings arises from a fact that it offers vertical expansion, making them an ideal choice for maximizing available urban space without influencing valuable land resources. A thorough literature review has conducted for comparative study of RCC and Composite buildings and its various advancements conducted before. This paper is based on regular and irregular plan area under different soil conditions. Total 18 cases have taken for consideration (6- square shape, 6 – L shape and 6 – T shape plan) with 3 cases each of RCC and 3 cases for Composite building and method selected - Response Spectrum Method. Results for Square shape plan shows that SCPH case i.e. Square plan with Composite structure over hard soil performs well in most of the output parameters. Results for L shape plan shows that LCPH case i.e. L shape plan with Composite structure over hard soil performs well in most of the output parameters while in case of story displacement and drift LRCCH i.e. L shape plan with RCC structure over hard soil performs better but the values of LCPH are also within the limits of IS codes. Results for T shape plan shows that in case of story displacement and drift TRCCH i.e. T shape plan with RCC structure over hard soil performs better because of the higher stiffness of RCC structure while in all other output parameters TCPH i.e. T shape plan with composite structure over hard soil performs well. Concluding the research work, use of composite structure performs well and can be used with building stability techniques so that the displacement factors can be minimized for composite structures.
