In the structure of elastic stage, the calculation accuracy under the distribution of high equivalence and elastic multi-mode combination is higher than that under the distribution of del; while in the structure of plastic stage, the result is opposite.

• 在结构的弹性阶段,高度等效分布和弹性多振型组合分布下结构层间位移的计算精度比倒三角分布下的好,但当结构进入塑性阶段后,两者比倒三角分布下的计算精度差。
