梁格法的主要思路是将上部结构用一个等效梁格来模拟，将分散在板式或箱梁每一区段内的弯曲刚度和抗扭刚度集中于最邻近的等效梁格内，实际结构的纵向刚度集中于纵向梁格构件内，而横向刚度则集中于横向梁格构件内。

Many researchers have investigated the influence of AMF on vacuum arc. And most of them point out that uniformly distributed AMF is preferable. However, at higher current even under very uniform AMF, vacuum arc still tends to constrict, which will result in the failure of break. Further more, very strong uniform AMF has some disadvantages also.
