This concept of steel and concrete combination is applied to shear wall structures, i.e. steel concrete partial assembly (PEC) shear wall elements. At present, PEC members are utilized to assist the development of green buildings in China, and the development of steel-concrete structures is more and more concerned by academia, the business industry and the government due to excellent bearing, anti-seismic and fireproof performances of the steel-concrete structures. It is a necessary development direction for enterprises to introduce efficient and intelligent PEC component production lines.
