高桩码头横梁弯矩在空间和平面模型中差异的探讨

Differences of transverse beam bending moment between space and plain models for pile deck wharf

基于码头上部结构刚度分析和多个工程实例,给出在不同类型的荷载作用下,空间模型计算的横梁弯矩值与平面模型计算结果之间的比例关系。结果表明,一般在垂直方向的均布荷载作用下,空间模型的横梁弯矩值是平面模型的75%左右;在门机荷载作用下这一比例为60%左右。

Based on the stiffness analysis of topside structure and a variety of project cases, we illustrated the proportion of transverse beam bending moment in space model to the moment in plain model under different type of loads. The results show that the transverse beam bending moment in space model accounts for about 75%of the moment in plain model under vertical uniform distribution loads, while it accounts for about 60%under gantry crane loads.
