摘要
为解决多梁式结构"边梁达到效率,中梁超过效率;中梁达到效率,边梁未达到效率"的问题,基于MIDAS CIVIL软件,通过对调整控制计算值法和调整横向车列数法进行比较分析,结果发现2种方法均可兼顾边梁和中梁的荷载试验效率,调整控制计算值法达到试验效率的梁片数大于调整横向车列数法,而调整横向车列数法比调整计算控制值法在偏载工况下的偏载效应更加显著。
In order to solve the problem that the side beam reaches the efficiency while the middle beam exceeds the efficiency;the middle beam reaches the efficiency while the side beam does not reach the efficiency,based on MIDAS CIVIL,this paper makes an comparative analysis of adjusting the control calculation and adjusting the horizontal truck number.The results show that both of the two methods can take into account the load test efficiency of the side beam and the middle beam.The number of beams that achieve test efficiency in former method is greater than that in the latter,while the partial load effect is more obvious in partial load condition using the latter method.
