COMPARISON OF SEISMIC BEHAVIOR OF A STRUCTURE WITH COMPOSITE COLUMNS AND CONVENTIONAL COLUMNS IN VARIOUS SEISMIC ZONES AND SOIL CONDITIONS

Abstract

The majority of building structures are designed and constructed in reinforced concrete which is mainly depends upon availability of the constituent materials and the level of skill required in construction, as well as the practicality of design codes. R.C.C is no longer economical because of their increased dead load, hazardous formwork. However composite construction is a new concept for construction industry. The use of modern composite systems, allowing the erection of multi-story structural frames to proceed at pace, can make it economically prohibitive to delay the construction of each floor while concrete columns are cast. In Japan, however, the superior earthquake resistant properties of composite beam-columns have been long recognized and have become a commonly used for construction in that region. It was therefore necessary to develop seismic design criteria for typically used Indian structural systems, to advance the use of this efficient type of mixed construction. This Project shows comparison of various aspects of building. In this project a residential of G+15 multi-story building is studied for Response Spectrum Analysis using ETABS with the help of RCC column and Composite columns. Totally 24 models are carried out in various seismic zones and soil conditions. The results like storey drift, storey shear, storey bending, storey torsion, time period, frequency and storey stiffness values are compared for this 24 models.
