摘要
Abstract
Chinese standard "Earthquake Resistant Design Code" ( GB50011-2010) stipulates that the vertical earthquake peak effect coefficient is taken as 0. 65 times of the corresponding value on the horizontal direction. This article presents three components of strong earthquake data 292 groups, 584 items from the Midwest of the USA. The data were used to research the structural damping ratio and influence on the ratios ( V/H) of vertical response spectra V to horizontal response spectra H. The change pattern of the curves V/H with impacting of respective factor was analyzed. The magnitude of the epicenter, site, category and the influence of the damping factor on the spectrum V/H were studied. The influence of magnitude, the epicenter, site category and damping factor for the average spectrum ratio curve shape were studied and were then compared to the value 0. 65 specified in the standard. It is suggested that various factors influencing the ratio of advice type should be taken account in determining spectrum. The paper demonstrates the usability of the collected strong earthquake data and the credibility of the research results.关键词
