COMPARISON OF SEISMIC BEHAVIOR OF A STRUCTURE WITH COMPOSITE COLUMNS AND STEEL COLUMNS BY USING E-TABS SOFTWARE

Abstract

Most building structures are made of reinforced concrete, which is mostly determined by the accessibility of the component materials, the degree of construction expertise needed, and the applicability of design regulations. Due to its dangerous formwork and high dead load, R.C.C. is no longer cost-effective. Nonetheless, composite construction is a novel idea in the building sector. Delaying the building of each floor while concrete columns are cast may be economically prohibitive due to the usage of contemporary composite technologies, which enable the creation of multi-story structural frames to continue at a rapid rate. However, composite beam-columns' greater earthquake resistance has long been acknowledged in Japan, where they are now often used in building. Therefore, in order to promote the adoption of this effective kind of mixed construction, seismic design standards for commonly used Indian structural systems have to be developed. This project compares different building characteristics.
This research uses ETABS to study a residential G+15 multi-story building for pushover analysis, assuming that linear, static, and dynamic analysis of material properties is carried out. Several metrics, including displacement, storey drift, performance point, and base shear, are shown as part of these non-linear analyses. These days, it is essential that all structures be examined and built to withstand lateral pressures like wind and earthquakes. However, in the construction of multistory buildings, it is often seen that the cross sectional area of RCC structural members comes out quite heavy with a big quantity of component material, such as steel & concrete, which takes up a lot of space. One of the greatest solutions in these situations is a composite construction, which not only protects against seismic stresses but also reduces the cross sectional area of structural members and offers a lot of space for economical use.
