(1 Nanjing Architectural Design ＆Research Institute Limited Liability Company, Nanjing 210006, China; 2 College of Civil Engineering, Nanjing University of Technology, Nanjing 210009, China)Abstract: Suqian Business Center Building is the reinforced concrete frame-shear wall structure, its design basic acceleration of ground motion is 0.3g, and the energy-dissipated braces are installed in some floors to increase the local structural damping ratio and reduce the dislpacement reaction under efuthquake, because the dislpacements of some floors exceed the requirement of design code. Calculation results of the nonlinear time-history analysis show that, adding the energy-dissipated braces in frame-shear wall structures can control the displacements of weak floors economically, and increase the structural seismic capability. The design method can be utilised for the design of similar projects in the region of high earthquake intensity.
Keywords: energy-dissipated brace; frame-shear wall structure; viscous damper; time-history analysis
