Structural Design for Three Steel Frame Built on the Existed RC Structure/Sha Zhiguo(Beijing Zhudu Fangyuan Architectural Design Co.,Ltd.,Beijing 100035,China)
Abstract:A steel structure with three floors built on the existed RC structure with three layers are calculated and designed.For satisfying the safety of the added floors building,the energy dissipation braces are used to reduce the seismic reaction of the existed structure.This measure can avoid reinforcing the existed RC structure.The detail of connection of joints is produced for steel columns  with the existed RC column.
Keywords:energy dissipation brace;seismic;steel structure;RC structure
