摘要
针对弹性长桩,采用“m”法求解弹性挠曲微分方程,求得桩的抗弯刚度,把单桩(单排桩)等代成一抗弯刚度相同的两端刚接的柱子,与上部结构以及拉梁一起进行共同作用内力分析,从而求出桩柱的偏心荷载对拉梁的影响。通过算例的计算可知,在规范允许的最大桩偏位情况下,拉梁的弯矩和配筋比无偏位的有大幅度的增加,并提出了拉梁内力计算方法。
For the long elastic pile,the m method is used to solve the elastic deflection differential equation and the bending rigidity can be obtained.The single pile can be replaced by one fixed at two ends with the same rigidity,and be analyzed with the upper structure and the base beam.The influence of the eccentric load on base beam can be calculated.The analysis of an example shows that the bending moment and the reinforcement of base beam increases greatly in the scope of allowable maximum deflection stipulated by the code.The calculation method of the internal forces of base beam is put forward.
