【摘要】 古北财富中心主楼结构方案综合考虑结构抗震性能、建筑的功能、设备的布置及经济性后,采用屈曲约束支撑-钢框架结构体系。柱网为9.2m×9.2m,9.2m×(14-17.8)m,结构特点为大柱距、核芯区偏心布置。支撑布置的范围由于受到建筑立面和设备的限制,只能集中在楼梯和电梯间周围。工程选择普通支撑框架和屈曲约束支撑框架两种结构方案,从抗震性能、建筑功能及经济性等方面进行了综合比较。最后就屈曲约束支撑框架在工程中的应用作了进一步阐述。更多还原

【Abstract】 The building,considering seismic performance,architectural and mechanic planning requirements and cost saving,is designed as steel BRB-frame structure.Columns grids of 9.2m×9.2m and 9.2m×(14～17.8)m are used in most areas.The structural characteristics are large span,and cores eccentricity.The braces are located only around stairs and elevators because of the restriction from architectural and mechanic planning.Ordinary brace-frame and BRB-frame structure are chosen,and the comparison in seismic performance,architecture functions,mechanic settings and cost saving is made.At last the BRB-frame is discussed for the high-rise steel structure.更多还原
