六层框架楼的内力组合形式.doc

内力组合 各种荷载情况下的框架内力求得后，根据最不利又是可能的原则进行内力组合。当考虑结构塑性内力重分布的有利影响时，应在内力组合之前对竖向荷载作用下的内力进行调幅。其中在恒载作用下，对梁端负弯矩进行调幅，调幅系数为0.8，而且当梁端负弯矩减小后，应按平衡条件计算调幅后的跨中弯矩，调整后梁跨中正弯矩至少应取按简支梁计算的跨中弯矩的一半，即。在活载作用下，采用满跨布置荷载的方法，对梁端负弯矩进行调幅，调幅系数也为0.8，而且当梁端负弯矩减小后，应按平衡条件计算调幅后的跨中弯矩。但在满跨布置荷载时，求得的梁的跨中弯矩比最不利荷载位置法的计算结果要小，因此对跨中弯矩应乘以1.2的系数予以增大。调整后梁跨中正弯矩至少应取按简支梁计算的跨中弯矩的一半，即。分别考虑恒荷载和活荷载有可变荷载效应控制的组合和由永久荷载效应控制的组合，并比较两种组合的内力，取最不利者。由于构件控制截面的内力值应取自支座边缘处，为此，进行组合前，应先计算各控制截面处的（支座边缘处的）内力值。梁支座边缘处的内力值： 式中 -支座边缘截面的弯矩标准值； -支座边缘截面的剪力标准值； -梁柱中线交点处的弯矩标准值； - 与相应的梁柱中线交点处的剪力标准值； -梁单位长度的均布荷载标准值； -梁端支座宽度（即柱截面高度）。 柱上端控制截面在上层的梁底，柱下端控制截面在下层梁顶。按轴线计算简图算得的柱端内力值，宜换算到控制截面处的值。1表 1 恒载作用下梁端弯矩调幅和调幅后剪力计算（调幅系数0.8）
