【摘要】 对高桩梁板式码头上部结构中的轨道梁、纵梁及横梁,在竖向荷载作用下的内力计算,提出考虑其空间整体受力作用特性的简化计算方法——荷载分配法,即将设计荷载乘以小于1的分配系数,然后仍然按规范法计算其内力。 计算结果表明本文法比规范法减少内力35％左右,接近于空间有限单元法,但计算远比有限单元法简便。更多还原

【Abstract】 This paper proposes a simplified calculation method--load distribution me-thod for calculating the internai force in the crane track beam ,longitudinal beam and transverse beam of superstructure for a pile-supported wharf under the action of vertical loads and considering the whole superstucture to be three-dimensional space in supporting those loads. By multiplying the design loads with a distribution coefficient which is smaller than l, the calculation of internai force may stili follow the conventional method suggested by the design code.The results of calculation show that the value of internai force calculated by the method in this paper can be reduced by about 35% as compared with the method by design code. The calculated results by the proposed method are close to those obtalned by spatial finite-element method, but it is rather easier than the latter.更多还原
