| 摘 要： | 超限高层结构在某一方面或多个方面存在与抗震概念设计不相符合的情况.塔楼存在扭转不规则、楼板不连续、塔楼偏置等问题,属于超限高层.本项目采用SATWE和PMSAP两个不同力学模型,对上海浦东新区某高层建筑的塔楼进行计算和对比分析.结果表明,两种模型计算得出的结构指标基本一致,刚重比、周期比、剪重比等均满足规范要求,并针对塔楼扭转不规则、偏心布置、楼板不连续、体型收进、超长结构等超限情况给出了具体措施.

| Abstract: | Out-of-code super high-rise buildings generally in one or some pects do not conform to the seismic concept design.The tower of such structures usually is of the features of torsional irregularity,tower bias,floor discontinuities,etc.The analysis of a certain out-of-code super high-rise building in Shanghai was carried out by using the programs of SATWE and PMSAP.The results show that the structural parameters calculated by either program are basically the same.The parameters of rigidity-weight ratio,period ratio and shear-weight ratio satisfy the requirements of the codes.Detailed measures were provided aiming at dealing with the out-of-code factors,such as the torsional irregularity,tower bias,floor discontinuities,setback and super-long structure. |
