莲塘口岸旅检大楼结构设计

Structural design of Liantang Port Passengers Inspection Building

莲塘口岸是联系深圳和香港的重要口岸,其旅检大楼属于特别不规则的超限高层建筑。着重介绍了结构设计解决的几个难点问题:大型货柜车从旅检大楼的地下室顶板通过时其等效荷载的确定及引起的整体结构振动舒适度分析;大角度倾斜的框架柱在梁板内引起的水平力的传递路径及处理办法分析;外露面积很大的2层高架平台的温度应力分析。通过分析找到结构受力的内在规律,并采取相应措施以确保结构的安全和正常使用。

Liantang Port is an important port which connects Shenzhen and Hong Kong,and Passengers Inspection Building of Liantang Port belongs to irregular out-of-code high-rise building. Several difficult problems solved in the structural design were introduced in detail： how to determine the equivalent load of the heavy container trucks that pass through the basement roof of Passengers Inspection Building and how to analysis the comfort degree of the main structure caused by vibration;analyses of transfer path and processing method of horizontal force caused by large angle inclined frame columns; analysis of temperature stress of the two-layer elevated platform which has a very great exposed area. Through the analyses,the inherent law of the structure mechanism was found,and the corresponding measures were taken to ensure the structural safety and normal use.
