| 摘 要： | 针对土木工程中相邻结构的碰撞问题，提出了一个新的分析模型，即建立碰撞附加速度约束条件，然后求解冲量形式的动力方程．碰撞力以约束力冲量的方式出现在动力方程当中，无需预先求解，并给出了求解结束之后直接通过单元处理求得撞击力的方法．算例分析表明，该模型在分析结构之间的碰撞时是有效的．

| Abstract: | A new model of pounding between adjacent structures was brought forward. By establishing the pounding-imposed velocity restraint condition, the pounding analysis is carried out by solving the equations of motion in impulse. The impact force is incorporated implicitly into the governing equations in terms of constraint impulse, which need not be obtained in advance. Moreover, it can be traced out by simple element handling if necessary. In the end, pounding analysis between two frames was performed to show the efficiency of the presented model. |
