Evaluation of the seismic performance of lightweight concrete multistory buildings

Abstract

In recent years, lightweight concrete has become very popular in the construction industry. And, its usage can lead to reduced costs and time. Therefore, different types of concrete (lightweight (LC), heavyweight (HC), and ordinary concrete (OC)) have been investigated to comprehend their response to earthquake load. Also, the comparison between their responses has been considered for getting the best response for various materials in construction work. The results prove that building models with LC are more resistant to earthquakes than the other types due to the reduction in the weight of buildings. Consequently, it has a role in resisting seismic forces. Furthermore, the combination of different concrete in the structural elements is another important criterion to be considered in thesis. The findings demonstrate that the responses in models for OCC-LCR (ordinary concrete for the column and light concrete for the roof) and LCC-OCR (light concrete column and ordinary concrete roof) have fewer values than the other types.
