Due to the increased demand for luxurious residential buildings and advancements in architectural software, structural engineers are now required to analyse and design more complex structures. These structures are often irregular in shape and mass distribution. In this work, we present a case study of a G + 3 reinforced concrete residential building that includes a swimming pool. According to IS-1893:2016, the structure falls under mass irregularity due to the presence of the swimming pool. The nonlinear static and dynamic analysis is performed for various seismic conditions and alternative positions of the swimming pool. Housner’s model is used to simulate the effect of splashing and water levels. The numerical analysis compares the structure’s responses for base shear, story drift, and displacement.

摘要

Due to the increased demand for luxurious residential buildings and advancements in architectural software, structural engineers are now required to analyse and design more complex structures. These structures are often irregular in shape and mass distribution. In this work, we present a case study of a G + 3 reinforced concrete residential building that includes a swimming pool. According to IS-1893:2016, the structure falls under mass irregularity due to the presence of the swimming pool. The nonlinear static and dynamic analysis is performed for various seismic conditions and alternative positions of the swimming pool. Housner’s model is used to simulate the effect of splashing and water levels. The numerical analysis compares the structure’s responses for base shear, story drift, and displacement.
