摘要

对于非比例阻尼线性体系,可以采用基于反应谱的复振型完全平方组合(CCQC)法和复振型平方和开方(CSRSS)法,而目前各国规范采用的仍是基于实模态的强迫解耦法。通过算例对复振型组合方法和强迫解耦法的误差及其与非比例阻尼特征指数的关系进行分析比较,并提出非比例阻尼线性体系复振型组合方法和强迫解耦法的适用范围。
For non-classically damped linear system,the complex mode complete quadratic combination(CCQC) method and complex mode square root of sum of squares(CSRSS) method based on response spectra can be adopted.And in overseas seismic design codes,the forced decoupling method based on real mode is still adopted.The relation with index of damping non-proportionality and the errors of complex mode combination methods and forced decoupling method were analyzed and compared.The application scope of complex mode combination methods and forced decoupling method for non-classically damped linear system were discussed.
