Comparative Study of modeling of shallow foundation on low-rise building subjected to earthquake loading

Abstract

When the low-rise building, which is located on shallow foundation, is subjected to an earthquake loading, the shallow foundation is usually considered as fixed supports or pinned supports. However, The earthquake loading will apply the horizontal movement and rotational movement to the foundation. Thus, the soil-structure interaction shall be taken into account for shallow foundation modeling as well. This research is purposed to study the modeling result of the shallow foundation by using three types of support condition. Those are fixed support, pin support, and spring support under an earthquake loading. Then, it will be compared to find the type of support that is suitable for each soil layer in order to design the building that is capable to resist the earthquake loading. The Seismic resistant building design standard (DPT 1301/1302-61) is employed to be used for analysis of the movement of buildings and to compare the modeling result between fixed support, pinned support and spring support.
