摘要
应用ANSYS软件对一屈曲约束支撑钢框架算例进行数值模拟,基于增量动力分析法,初步探讨了屈曲约束支撑钢框架的结构影响系数。结果表明,结构超强系数对结构影响系数的影响远大于结构延性折减系数,在结构影响系数的构成中结构超强系数占主导地位。
An calculation example of BRBFS was numerically simulated using finite element software ANSYS.The structural influencing coefficient was investigated based on incremental dynamic analysis(IDA)method.The results showed that the structural overstrength factor played a main role which had an much greater effect on the structural influencing coefficient than the ductility reduction factor.
