SEISMIC ANALYSIS OF BUILDINGS WITH AND WITHOUT SHEAR WALL ON DIFFERENT TYPES OF SOIL

Abstract

Civil engineering is always deals with constructing different types of structures with ensuring safety, durability and serviceability. Now days “earthquake “is phenomena that affects the structures with their safety and serviceability. The amount of damage that earthquake can done to structures is depend on Type of building, Type of soil, Technology used for earthquake resistance, and last but not the least Location of building. Effects of earthquake is largely depend on type of soil in which foundation of building is done because earthquake changes the motion of ground that results the failure foundation. So it is important to study the behaviour of different soil at the time of construction of structures. Also earthquake can resisted by various technologies used in building, one of these are shear wall. It improves the structural performance of building subjected to lateral forces due to earthquake excitation.
This paper aims to study, understand and analyse the critical behaviour of RCC frame structures with and without shear wall on hard, medium and soft soil strata subjected to seismic loading. Lateral displacement, base shear, storey displacement are the main parameters that are calculated and compared for all 5 models with different location of shear wall. This paper not only covers the behaviour of building with and without shear wall but it also helps to understand the behaviour of building for different locations of shear wall. All RCC frame models are modelled in ETABS software. Output from software consisting of Pushover curve and storey displacement results of all 5 models are presented, which helps to design the structures in order to reduce the effect of seismic forces.
