Clough-Penzien参数选取在公共工程项目管理决策中的应用
|
摘要
Clough-Penzien模型的参数合理选取在公共工程项目管理的前期设计决策中起着至关重要的作用,不仅关系公共工程项目安全性,也关系到公共项目管理的经济性。分析中参照国际知名学者的取值方法,给出了与我国规范相适应的模型设计参数。研究表明:合理的模型设计参数应当对场地条件(软土、硬土)有明显的区分度,为应用随振动理论进行公共工程项目抗震设计及管理分析提供了依据,并成功运用到河南电视塔项目的管理实施中。
It is important to select the parameters of Clough-Penzien seismic random model reasonably in the prophase design decision of public engineering project.It not only relates to public project's safety,but also relates to the economy of management of the public project.The model design parameters,which adapt with the GB50011-2001 code,are given on the basis of the world famous scholar's method for the analysis.The results show that the appropriate parameters should be distinct for different site conditions.The parameters given in this study provide a theoretical fundament for stochastic seismic response analysis of structures in public project and the result is successfully applied to the management and implementation of Henan TV Tower Project.
