中文摘要：
本文建立了适合框架结构倒塌分析的离散单元模型，并且研究了模型的破坏准则、阻尼等参数确定方法。对框架结构在地震作用下的倒塌全过程进行了数值分析和可视化仿真模拟。算例表明，本文方法是有效的，可以较正确地分析剪切型框架结构的倒塌破坏过程。
英文摘要：
In this paper, a discrete element model for collapse simulation of frame structures is developed. The failure criterion and determination of analytical parameters such as damping are also studied. The seismic collapse process of frame structures is numerically analyzed and visually simulated. The results show that the methods developed in this paper are reliable, which can reasonably simulate the seismic collapse process of reufforced concrete frame structures with shear type deformation.
