西宁市市民中心结构设计

Structural design of the Civil Center of Xining City

介绍了西宁市市民中心的结构设计,该建筑平面形状和立面形状均较为复杂,平面存在楼板开大洞、大悬挑、局部穿层柱、斜柱等不规则项,详细介绍了对薄弱部位及对结构不规则项所采取的措施,对屋顶45m和27m大跨分别采用倒三角钢管桁架及实腹钢梁体系。结果表明通过合理的结构布置和性能目标确定及采取适当的构造措施,可较好地解决工程设计中的问题,可供同类工程设计参考。

The structural design of the Civil Center of Xining city was introduced,the plane shape and facade shape of the building are complex.There are irregular items such as open holes,large suspensions,partial trapezium columns,and oblique columns in the plane.The measures taken for vulnerable areas and structural irregularities were described in detail.The inverted triangular steel pipe truss and the solid abdominal steel beam system were applied to the 45 m and 27 m span of the roof.The results show that the problems in the engineering design can be solved by the rational structure arrangement,the determination of performance targets,and the appropriate structural measures.It can be used as reference for similar engineering design.
