Structural Design and Analysis of a High-rise Building

由于建筑平面、立面上的需求,结构存在扭转不规则、偏心布置、多塔、竖向构件不连续、连体等问题,存在三项及以上抗震不规则。采用YJK、ETABS、SAUSAGE软件对结构在多遇地震、偶遇地震、罕遇地震情况下进行分析计算,能满足各项抗震性能要求。对转换层楼板应力、连廊连体结构等进行专项分析,通过专项分析加强后,结构能达到规范要求的各项性能目标。

Due to the needs of the building plane and elevation,the structure has problems such as irregular torsion,eccentric arrangement,multiple towers,discontinuity of vertical components,and connection,and there are three or more seismic irregularities.YJK,ETABS and SAUSAGE software were used to analyze and calculated the structure in the case of frequent,occasional and rare earthquakes,which can meet the seismic performance requirements.Special analysis was conducted on the stress of the transfer floor and the connected structure of the corridor.After special analysis,the structure can reach the performance objectives required by the code.
