| 摘 要： | 分析了混凝土收缩徐变对深圳长富金茂大厦构件内力和变形的影响规律,总体趋势是随着楼层高度的增加,影响越发明显,具体结论如下:1)混凝土收缩徐变对框架柱的轴力起增大作用,顶层处增大幅度不超过10%,对剪力墙的轴力起释放作用,顶层处减小最大为27%;2)对一端连接柱子、一端连接剪力墙的梁端弯矩影响较大,其中顶层处近柱端的梁上部弯矩增大接近30%,近墙端的梁上部弯矩减小接近20%;3)对两端连接框架柱的梁弯矩影响最大接近11%;4)一端连接柱子、一端连接剪力墙的梁端弯矩影响主要为最顶部10层,中下部的影响可以忽略不计。基于该影响规律,对结构设计施工措施提出了相应的建议。

| Abstract: | The impact of concrete shrinkage and creep on component internal force and deformation of Changfu Jinmao Building was analyzed.It is concluded that the general trend is that the effect is more obvious with the increase of floor numbers.The specific conclusions are as follow: 1) concrete shrinkage and creep is enlarging the axial force in the column with the increase range not exceeding 10% on the top floor,but is decreasing the axial force in the shear wall with a maximum of 27% on the top floor;2) the impa... |
