[摘要] 宿迁经济开发区商务中心为框剪结构，按8度(0.3g)进行抗震设防，由于建筑部分楼层层间位移超过规范要求，因此在部分楼层增设粘滞阻尼消能支撑，通过提高结构的附加阻尼比来降低结构的位移反应。整体结构的非线性时程分析结果表明，通过在框剪结构中增设消能支撑，可以较为经济地控制结构的楼层位移，提高结构的抗震安全储备。本文可为高烈度区类似工程的设计提供借鉴。

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
