【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。更多还原

【Abstract】 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.更多还原
