摘　　要：基于Abaqus软件平台,利用FORTRAN语言二次开发了一种剪切型金属阻尼器用户子单元(UEL)。通过与Abaqus软件库中用于近似模拟阻尼器的单元进行比较,验证了该用户子单元的正确性,为Abaqus软件二次开发提供了参考。与软件库自带的单元相比,该用户子单元参数输入简单,无需试算,动力分析下的滞回性能更明显。同时,本文对软件中的不同单元进行了探讨,为剪切型金属阻尼器的模拟提供了新的思路。An user-defined element （UEL）simulating a type of shear-yield metal damper is developed in FORTRAN language based on the Abaqus software.Through the comparision with other elements in Abaqus element liabrary,the validity of this UEL is proved,providing a reference in Abaqus secondary development.In comparison with the elements in Abaqus that could be used to simulate dampers,the input parameters of this UEL are simpler and more clear without repeating trial running,the hysteretic behavior is also better under dynamic analysis.A discussion of different elements that could be used to simulate the shear-yield metal damper in Abaqus is also conducted in this paper,offering a new way of damper simulation.
