Seismic Assessment of the Typical RC Building of the Egyptian Social Housing Program
摘要
The Egyptian Social Housing Program (ESHP) is a national project launched in 2014, that aims to construct one million residential units around the country. Within the framework of the ESHP, more than 26,700 Reinforced Concrete (RC) buildings have been constructed; each has 24 residential units. An additional 15,000 buildings will be constructed by 2030. It was noted that an almost identical design for the RC superstructure was adopted for all constructed buildings regardless of their seismic zone. To ensure the safety and resilience of this ESHP typical design to withstand future earthquakes, a performance-based evaluation was conducted for the ESHP typical RC building using SeismoBuild software. Nonlinear pushover analysis of the ESHP typical RC building was performed. The capacity and demand curves were compared to assess the seismic resistance of the ESHP building in the various seismic zones located in Egypt. The global performance of the ESHP building was investigated in terms of the lateral capacity curves with performance points in different seismic zones. Additionally, the inter-story drift ratios were assessed to identify the damage quantities along the building stories. Furthermore, the local performance of the primary structural elements was evaluated in terms of the generation of the plastic hinges and the shear failure. The results showed that the ESHP buildings have adequate performance in all the seismic zones of Egypt with recommendations for design enhancements in only the highest two seismic zones.
