Steel Structural Design of Shimao Chasm Hotel

系统介绍了世茂深坑酒店的钢结构设计,着重阐述了该结构的关键节点设计,对酒店钢结构框架进行了施工过程分析。结果表明:结构上端有很强的约束,刚度较大,宜选取延性较好的钢框架-支撑结构;楼板刚度对结构构件受力有显著影响,构件设计时须取不同楼板刚度计算模型下的包络结果;采用带肋钢铺板组合楼板可有效解决混凝土板受拉问题。

The steel structural design of Shimao Chasm Hotel was introduced systemically, and the structural key joint＇s design was emphasized. Meanwhile, the construction process analysis of steel structural frame for Shimao Chasm Hotel was carried out. The results show that the upper structure has a strong constraint and large stiffness, the steel frame-support structure with the better ductility should be chosen. The slab stiffness has a significant influence on the force of main structural members, so the envelope results of different slab stiffness should be considered in the members＇ design. The composite slab with ribbed steel decking can effectively solve the tension problems of the concrete slab.
