剪切域-
If the inputted accelerations are velocity - zeroized and the damage value is calculated according to shear stress " extrema, as to 100 - meter - high earth dam, multi - point effect is not distinct ; but as to 240 - meter - high earth dam, in the part where permanent displacement and damage value is originally bigger the response is less tenser than that by one - point input, and in the part near basement the maximal shear stress and damage value is bigger, that is the multi - point effect in time domain
若同時進行了多點地震動速度歸零化和採用基於極值的損傷值計算方法，對於100米高的土石壩，多點輸入與單點輸入反應十分接近。對於240米高的超大型土石壩，壩體內永久位移和損傷值較大的部位多點輸入的反應量較小，這是多點輸入反應的特點或說多點效應。另外，多點效應也包括壩基部位的最大動剪應力和損傷值偏大這一效應。
