针对内河框架码头排架间设置纵撑这一特点，采用ANSYS有限元软件，计算框架码头各工况水平力作用下的分配系数，发现框架码头在水平力作用下呈刚体性质，当作用力在边跨最底层时荷载最集中，可作为桩基受力验算的控制工况。在此基础上，定量分析有无纵撑以及纵撑材料（砼和钢）改变对分配系数的影响，得出设置纵撑能使受力排架分配系数减小15％以上，且混凝土纵撑比钢纵撑的作用提高10％以上。为了减小选用钢纵撑对结构受力的不利影响，本文以钢纵撑厚度和直径为研究对象，进行分配系数的敏感性分析，结果显示增大钢纵撑直径能有效地降低构件的受力集中程度。

It is one characteristic of inland frame wharf to set longitudinal bracing between two bent frames.ANASYS software was used to calculate the distributing coefficient of horizontal force with the frame wharf under different working conditions.On this basis,the influence of longitudinal bracing’s presence or absence and material (concrete or steel)of longitudinal bracing on distributing coefficient were analyzed quantitatively.The results shows that,setting longitudinal bracings could make the distrib-uting coefficient of stressed bent be decreased by over 15%.Meanwhile,the distributing coefficient could be reduced by over 10%if the steel longitudinal bracings are replaced by concrete longitudinal bracing.In order to reduce the negative influence caused by steel longitudinal bracing,the thickness and diameter of steel longitudinal bracing were focused to take the sensitive analysis of distributing coefficients,and the result shows that stress concentration could be reduced effectively by increasing the diameter of longitudinal.
