摘要 基于拟力法基本理论,建立了考虑塑性铰外移的消能减震结构计算模型,即把塑性铰的可能位置由构件端点移至距离两端一定长度处.通过数值算例对比分析了塑性铰外移前后结构动力时程响应的变化,验证了考虑塑性铰外移的必要性和重要性.与传统拟力法相比,保留了其存储空间小和计算速度快的特点,也使模型更具实际意义. An analytical method of performing inelastic dynamic analysis of structures with dissipation devices based on force analogy method is proposed, containing the concept of plastic hinge offsets from member ends. Structural dynamic analysis with and without end offsets are performed in numerical simulation, which confirms the necessity and importance of considering end offsets. Compared to traditional force analogy method, the model retains the advantages of less need of storage and computing, and performs more practically.
