通过对塔式起重机基础发生地基沉降时,当整机受到垂直载荷和变幅平面内弯矩共同作用下的“十字梁”底座进行受力分析,给出了压重的确定方法及“十字梁”底座的计算方法。对这类结构的设计计算具有一定的参考价值。
Through the foundation settlement of the tower crane, when the whole machine is subjected to the force analysis by the vertical load and the bending moment in the luffing plane, the method of determining the weight of the crane is given. “Cross beam ” base of the calculation method. The design and calculation of such structures have a certain reference value.
