Special equipment for welding shear wall stiffeners and cooperative welding robots have been developed to improve the efficiency and quality of fabrication and installation; A wireless passive trigger sensor was developed to improve the efficiency of post earthquake damage detection.

A cast steel-concrete composite shear wall building system is proposed, and a complete set of technologies such as diaphragm semi through connection, unilateral bolt end plate connection and replaceable energy dissipation coupling beam are developed.

International advanced on June 30, 2022, the scientific and technological achievements appraisal meeting of “precast steel-concrete composite shear wall building system”, one of the major assembly product systems (MPC), hosted by the Engineering Research Institute of China Construction Eighth Engineering Bureau, was successfully held online.

The expert committee headed by he Mingxuan, the chief expert of China Baowu iron and Steel Group, agreed that the scientific research achievements generally reached the international advanced level! The appraisal meeting was organized by Shanghai Civil Engineering Society, and authoritative experts and scholars such as he Mingxuan, the chief expert of China Baowu iron and Steel Group, ye Guoqiang, the deputy chief engineer of Shanghai Tunnel Co., Ltd., Wang Pingshan, the deputy chief engineer of China Construction Group, Li Xin, the chief engineer of Shanghai Construction Engineering Design and Research Institute Co., Ltd., and Wang Wei, the deputy director of the Department of architectural engineering of Tongji University, served as appraisal experts; Liaoxiandong, vice president of the Engineering Research Institute of China Construction Eighth Engineering Bureau, and Chen Yueshi, Yang Qi, Li Chang, members of the project team attended the meeting.
