COMPARATIVE STUDY OF DESIGN VARIATIONS OF SIZES AND POSITIONS OF OPENINGS IN SHEARWALLS FOR HOTEL BUILDINGS ON SOFT LAND

Abstract

The soft soil found in Banjarmasin, South Kalimantan, has a low bearing capacity and tends to magnify the effects of earthquake-induced vibrations. This condition requires the planning of building structures that are able to withstand lateral forces adequately. One structural system that is often used to increase stiffness and lateral stability is a shear wall. The purpose of this study is to evaluate the building structure in response to earthquake force, both with and without shear wall elements. Modeling is done using Tekla Structure Designer software, response parameters in the form of inter-story Deviation (drift) and base shear force (base shear). The analysis shows that the use of shear walls without openings provides more optimal results in resisting earthquake loads. Structures with this element show lower drift values, more stable shear forces, and shorter vibration periods compared to structures without shear walls.
