Abstract This study presents a numerical assessment of the effects of tensioning and curvature on the impact resistance performance of a prestressed concrete wall. Specifically, a prestressing method and numerical analysis method applying an impact load-time function are proposed and described. To transfer of initial prestress to the wall, the prestressing method employs a thermal load and appropriate boundary conditions are selected for the wall end to generate appropriate deformation on the wall due to prestress. The differences in impact resistance performance are then compared and analyzed according to variations in the curvature and prestress of the wall. The impact analysis results show that the degree of displacement and damage to the wall decreases for all wall shapes with a higher prestressing ratio. Furthermore, cylindrical and hemispherical walls relative to flat walls verify that the arching effect generated by the curvature of the wall reduces the displacement response of the wall.

考虑曲率和后张效应的预应力混凝土结构局部抗冲击性能分析

摘要 本研究对张拉和曲率对预应力混凝土墙抗冲击性能的影响进行了数值评估。具体而言，提出并描述了应用冲击载荷-时间函数的预应力方法和数值分析方法。为了将初始预应力传递到墙体，预应力法采用热载荷，并为墙体端部选择合适的边界条件，使墙体由于预应力而产生适当的变形。然后根据墙体曲率和预应力的变化比较和分析抗冲击性能的差异。冲击分析结果表明，对于所有具有较高预应力比的墙体形状，墙体的位移和损坏程度均减小。此外，
