摘要
大连东北亚国际航运中心总部大厦为超B级高度的超限高层建筑,建筑高度245.8m,建筑造型呈中区大、低区和高区小的梭形,存在跃层构件、斜柱、楼板不连续等三项不规则类型。采用钢筋混凝土框架-核心筒结构体系,对跃层构件的屈曲、斜柱转折、干缩与徐变的影响、钢骨梁柱节点和罕遇地震弹塑性分析等进行了探讨,并根据分析结果,对关键和重要构件进行适当加强,在构造措施方面亦进行相应处理。结果表明,整体结构及构件的抗震性能均满足抗震性能目标,项目各项不规则程度得到了有效改善,结构体系合理、安全、有效,保证了项目施工的顺利进行。
Dalian Northeast Asia ISC Headquarter is an over⁃limit high⁃rise building with a height of over B,with a building height of 245.8m.The building shape is fusiform with large in the middle area,small in the low area and the high area.There are three types of irregularities,such as jump members,inclined column and floor discontinuity.Based on the reinforced concrete frame⁃core tube structure system,the buckling of members,inclined column transition,dry shrinkage and creep effects,steel beam⁃column joints and rare earthquake elastic⁃plastic analysis of the stratocline members were discussed.According to the analysis results,the key and important members were appropriately strengthened and the corresponding structural measures were also treated.The results show that the seismic performance of the whole structure and components can meet the seismic performance target,the irregular degree of the project has been effectively improved,and the structural system is reasonable,safe and effective,which ensures the smooth construction of the project.
