摘要
在对规范和文献资料的研究和分析的基础上,本文探讨了(超)高层建筑、巨型储油罐、大跨桥梁工程等重大建设工程基本自振周期的估算方法。在工程场地地震安全性评价工作中,可采用本文提供的重大建设工程基本自振周期估算的公式。同时,本文为长周期地震动对工程结构作用的相关参数的合理确定提供了依据。
Based on the research and analysis on the codes and data, estimation measures of fundamental vibration period of major construction projects, such as super high-rise building, jumbo oil tanks and large-span bridges, are discussed. Our results will help to provide the estimation measures for determination of important parameters of the action on engineering structures applied by the long-period earthquake motion in the evaluation of seismic safety for engineering sites.
