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
