摘　　要：提出三维均质体中法向均布载荷作用下的椭圆平片裂纹区域Ｓ内超奇异积分∫ｓ＋ｒ－３ΔｕｄＳ的封闭解法，解法应用了裂纹表面位移间断具有平方根的特性．The response of secondary structure on the top greater than that of primary one in earthquake will consume some energy of the primary structure. This will cut down the vibration of primary system. In this paper, the energy dissipation of secondary system on plastic has been analysed and its effect of shock absorption on primary structure has been discussed.
