工程位于6度抗震设防区,为7层钢结构办公楼,平面、竖向均不规则,楼层两侧开洞,中部门厅凹凸不规则,顶层为半连体结构,属特别不规则结构体系,依据结构抗震概念进行几何与构造加强设计。结构弹性分析及弹塑性分析表明,结构布置能够达到小震弹性、中震可修、大震不倒的性能目标。 The project is located in the 6-degree seismic fortification zone and is a 7-storey steel structure office building. It is irregular in plane and vertical with openings on both sides of the floor. The irregularities in the central entrance hall and the semi-continuous structure at the top are specially irregular structural systems , According to the concept of structural seismic geometry and structure to strengthen the design. Structural elasticity analysis and elasto-plastic analysis show that the structural arrangement can achieve the performance target of small earthquake resilience, moderate earthquake repairing and large earthquake collapse.
