摘要
采用桩基剪力法、弹性支撑刚性梁法等多种方法对水平荷载作用下的变刚度多层框架码头的空间特性及排架分配系数进行计算与比较分析,结果表明:桩基剪力法能更好地反映出结构的空间特性;在排架刚度变化幅度不大的情况下,弹性支撑刚性梁法的计算结果与规范中的排架分配系数接近。在此基础上,通过改变大刚度排架的刚度值及位置,得出排架间刚度差异、大刚度排架位置与分配系数的相互关系;分析空间特性及面板刚度对水平分配系数的影响。
By using several methods such as pile shear method, elastic supported rigid beam method, etc., we calculate, compare and analyze spatial characteristics and distribution coefficients of variable stiffness frame wharf under the action of horizontal loads. The result shows that pile shear method is more suitable to indicate spatial characteristics of the frame wharf. When the stiffness between different bents is approximately similar, the distribution coefficients calculated by using elastic supported rigid beam method is similar to the value in the code. On this basis, correlation among the stiffness value, the position of the huge stiffness bent and distribution coefficient is studied by changing the stiffness value and the position. Meanwhile, the spatial characteristics of the frame wharf and the effect of face slab on distribution coefficients are analyzed.
