隔震结构等效线性化计算方法对比研究
Comparative study on equivalent linearization calculation method in design of seismic isolated structure
摘要
Abstract
200 equivalent linearization methods,composed of 10 calculation methods for equivalent period and equivalent damping ratios,4 damping scaling factors and 5 acceleration response spectra,were used to estimate the displacement response of 100 single degree of freedom models of seismic isolated structures with initial natural periods between 0.6-1.5 s and yield displacements between 2-11 mm.The results were compared with those from time-history analysis.The investigations show that the seismic response calculated by artificial waves matching the Chinese acceleration spectrum is larger than those calculated by other artificial waves matching the American,Japanese and European acceleration spectra,therefore the calculation has the high safety margin.Damping scaling factor is well matched with acceleration response spectrum in American,Japanese and European codes,and high precision result can be obtained by the adoption of reasonable equivalent parameters in equivalent linearization method.It's not accurate to analyze the isolated structure by using equivalent linearization method including Chinese acceleration response spectrum with the existing equivalent parameters and damping scaling factor.关键词
