【摘要】 针对网格结构设计中吊车荷载最不利组合计算不精确的问题，依据影响面理论，基于一种通用的吊车计算模型，采用动态规划法将此最不利组合计算问题转化为递推求解一系列极值函数的问题，从而得到了合理的最不利值，并编制了相应程序。更多还原

【Abstract】 The imprecise computation problem of the worst combination of crane loads in the design of space grid structure is solved. According to the theory of influence surface,based on a general calculating model of crane, dynamic program method is used to transform the worst combination problem into solving a series of extremum functions with recursive relation, and the reasonable worst results are obtained. Corresponding computer programs are developed.更多还原
