摘要:柬埔寨当地没有系统的结构设计规范和相关标准,对于高层结构设计中的风荷载取值、地震作用计算及相关节点的连接处理等问题均大量参考中国相关规范. 以一个不规则 T 形平面高层结构设计为例,阐述了高层建筑结构设计时基本风压的取值过程,对结构整体进行了地震作用下的计算与优化,对结构薄弱部位进行加强处理,改进了钢筋混凝土外墙的柔性连接方式,对不连续的个别关键构件进行设计与验算. 分析结果表明:中国规范不能完全适用于柬埔寨当地的结构设计需要,中国设计人员需根据实际情况作出相应的修正,修正后的各项措施可以满足设计需要.

Abstract:There were no systematic structural design codes and relevant standards in Cambodia. The wind load value,seismic action calculation and connection treatment of relevant nodes in high⁃rise structure design were largely referred tothe relevant specifications of China. Taking an irregular T⁃shape plane high⁃rise structure design as an example, the valueprocess of basic wind pressure in structural design of high⁃rise building was expounded, calculation and optimization of thewhole structure under earthquake action, strengthening the weak parts of the structure, improvement of flexible connectionof reinforced concrete facades, design and checking of discontinuous individual key components were carried out. Theanalysis results show that the Chinese code was not fully applicable to the local structural design needs of Cambodia,Chinese designers needed to correspond modifications according to the actual situation, and the revised measures can meetthe design needs.

Keywords:Cambodia; high⁃rise structure; irregular T⁃shape plane; wind load value; structure optimization; flexible connection
