海南省政府办公楼超长结构无缝设计分析

Design and Analysis of Super-long Concrete Structure of Office Building of Hainan Provincial Government

海南省政府办公楼工程平面选型复杂,建筑平面长度达158 m,远超过规范规定的允许值,由于使用功能的特殊性和结构抗震整体性的要求,整个建筑物不允许设伸缩缝,该工程是海南省目前地上混凝土结构无缝设计最长的高层建筑。本文对该工程超长混凝土结构无缝设计、温度应力有限元分析及技术措施和施工要求等进行了全面的分析和阐述,通过各种有效计算方法和控制裂缝措施的实施,该工程在施工和使用阶段未出现任何形式的有害裂缝,保证了结构的安全可靠。提供了一些有价值的工程数据,可供同类型超长结构设计参考。

The office building of Hainan Provincial Government has a complex plan with 158 m,its plane length,which greaty exceeds the standardized regulations. Due to the particularity of service function and the demand of structural anti-seismic resistance, it is not allowed for the building to set up expansion joint. The construction is the longest high-rise building of concrete structure without expansion joint at Hainan Province. This article mainly analyzed and discusses in detail the seamless design of super-long concrete structure, finite element analysis of temperature stress , technical measure and construction management. By taking effective measures of various effective computing method and crack controlled, there is not harmful crack in this project during construction and service time, and the structural safety is guaranteed. This article provides some engineering datas of real worth, which may be used as reference for similar project design of super-long concrete structure.
