Through the analysis of commonly used peripheral protection systems for steel structure residential buildings,based on the steel frame structure system,an innovative research and design of thin-walled ribbed complex shaped ultra-high performance concrete(UHPC)external wall panels matching steel structure residential buildings was developed,forming a standardized steel structure residential+UHPC external wall panel system,including external wall panel design,connection joint construction design,joint waterproof sealing treatment.This system has been promoted and applied in a public residential building project in Beijing,playing a leading role in the innovative research,design,and rapid assembly construction of thin-walled ribbed UHPC external wall panels,and it has efficient construction characteristics.
