%X 为优化绿色钢结构建筑的安全性能与环保性能，基于一40层框架-支撑钢结构建筑实例进行抗震性能与环保性能分析。根据实际建筑参数构建该绿色钢结构建筑剖面图，基于时程分析法记录不同地震波作用下建筑水平位移随时间变化情况，基于Pushover分析法分析方钢管混凝土组合异形柱在罕见地震中的基底剪力和弹塑性变形，基于对比实验方法验证其环保优越性，并得出以下结论：建筑的方钢管混凝土组合异形柱符合国家抗震性能要求，整体建筑的抗震性能随楼层的增加而减弱；与钢筋混凝土结构、砖混结构相比，钢结构能有效节约施工水电用量、降低施工噪声，是一种抗震性强、环保性能优的绿色建筑形式。<br>To optimize the safety and environmental protection performance of green steel structure buildings, the seismic and environmental protection performances of a 40-story, steel-braced frame structure were analyzed. According to the actual building parameters, a profile of the green steel structure is presented, and the variations in horizontal displacement with time under different seismic waves were recorded using a time-history analysis method. Based on the Pushover analysis method, the base shear force and elastic-plastic deformation of special-shaped, square, concrete-filled steel tubular (SCFT) columns were analyzed under rare earthquakes conditions. Results of the comparative experiments lead to the following conclusions:the special-shaped SCFT building columns met national requirements for seismic performance. Compared with reinforced concrete and brick-concrete structures, green steel structures can effectively save water and electricity consumption during construction and reduce construction noise, and show strong earthquake resistance and excellent environmental protection
