全钢框架结构中设置偏心支撑的结构体系比较适用于抗震设防高烈度区,但受业主的传统认识、防火防腐问题和造价偏高、结构设计师的设计习惯等因素的影响,全钢结构房屋的应用受到一定程度限制。某高烈度区高层停车楼,采用了钢结构偏心支撑(消能梁为钢梁)+钢筋混凝土框架结构体系,对其进行静力弹塑性推覆分析,表明这种混合体系有较好的抗震性能,对于高烈度区的多层或高度偏低的高层建筑,具有很好的适用性。
The structural system of eccentrically braced steel frame structure is more suitable for seismic fortification zone, but the owners of traditional understanding, fire and corrosion problems and high cost, structural design habits of structural designers and other factors, all-steel structure housing The application has been limited to some extent. The high-rise parking lot in a high-intensity area adopts the eccentric support of steel structure (energy dissipation beam is steel beam) + reinforced concrete frame structure system, and its static elastoplastic pushover analysis shows that the hybrid system has better seismic performance, For high-intensity areas of multi-storey or high-rise high-rise buildings, has good applicability.
