Authors: Shu Ganping, Zhou xiongliang, Wang Xiaodun, Cai Yuchun, fan Shenggang, Cao Shi, he Yunfei, Chen Zhihua, Liu Jie, Chen Weigang, Qin Ying, Du Erfeng Abstract: in recent years, China has begun to vigorously promote the application of cast steel structure buildings, National and local governments have also launched a number of policies to encourage and promote its application and promotion.

Therefore, the cast steel structure building system has been widely developed.

Research institutions and enterprises such as Southeast University, Zhejiang southeast Grid Co., Ltd., Beijing Jinxi saibosi Architectural Design Co., Ltd.

and Tianjin University rely on the national key R & D project “industrialization technology and demonstration of new frame steel structure system” in the 13th five year plan to solve the problems of exposed beams and columns in the application of cast steel frame system buildings For the problems of low industrialization and complex construction, new steel frame structure building systems such as multi cavity column steel frame support, multi cavity frame steel plate composite shear wall, new frame core tube and concrete-filled steel tubular composite special-shaped column frame structure are proposed, and the key technologies in the new system construction are deeply studied and applied, It improves the technology and application level of cast steel structure buildings in China, and advantageously promotes the development of building industrialization in China.
