Response Spectrum Analysis with Regular and Irregular Structures with Diagrid Systems Using Etabs

Abstract

Abstract: One of the most catastrophic natural disasters is an earthquake. that wreak havoc on buildings and the loss of life. The irregularities of a building or an asymmetrical system are often found in construction due to the need for architecture view in buildings. Today, the use of buildings and economic barriers requires that vertical and unusual structures be built in urban areas. Therefore proposing measures to reduce the damage to these buildings during an earthquake is important. Strict rules of design and analysis of unusual structures have been applied in view of their high risk of injury compared to conventional structures. There are different types of structural deficiencies depending on their location and width, but most importantly, they are divided into two groups - horizontal irregularities and vertical irregularities. In the study, both irregularities are considered. The current paper seeks to investigate the proportional distribution of lateral forces arising from earthquake action at each floor level due to changes in the strength of the frame in the irregular structure. In accordance with the provisions of the Bureau of Indian Standard (BIS) 1893: 2002 (part1), the unusual G + 14 vertical building is modeled as a model of the simplified lump mass to analyze the rigidity of the floors. To analyse parameters such as storey drift, storey displacement and story base shear under seismic force under dynamic analysis are studied
