一、目前採用的計算方法所存在的問題 計算法簡介当载荷作用在侧架平面內(包括垂直载荷,及侧向载荷的部分力系)的情况下,铸钢侧架的计算简图为通过侧架各弦桿和立柱的断面重心的轴线所组成,这时的计算简图为一个由三个封闭格子组成的构架,因此在一般情况下;系一种九次超靜定的结构。利用当对称载荷作用下,在结构的对称截面中反对称的內力为零及当反对称载荷作
First, the calculation method used in the present problems Calculations Introduction When the load acting in the side plane (including vertical load, and lateral load partial force system), the calculation of the cast steel side frame through The side frame of each chord and column section of the center of gravity of the axis of the composition, then the calculation diagram for the three closed grid consisting of a framework, so in general; Department of a nine statically indeterminate structure. When the symmetrical load is used, the asymmetric internal force in the symmetrical section of the structure is zero and when the anti-symmetrical load is used
