| Research Abstract |
The impact features of structures depend on the rapid variation for structural stiffnesses and the impulse of external loads. This study clarified as the following items. (1) formulation of a simplified theory which is solvable the local stress distribution of high-rise buildings with rapid variation of stiffness such as a setback ;(2) finding out the cause of the astonishing magnitude of vertical acceleration and the wave form ;(3) explication of interaction between the effect due to external loads and the dead loads ;(4) impact effect of pounding between adjacent buildings and the reduction of pounding damages ; and (5) clarification of beams and plates subjected to impact loads.
