基于最优设防烈度的抗震结构寿命周期费用最小模型研究
|
摘要
提出的优化模型基于最新《建筑抗震设计规范》(GB 50011—2010)(2016版),使结构寿命周期费用最小。首先决策出最优设防烈度,然后进行结构参数优化设计。结构各级破坏的概率可根据场地基本烈度和结构设防烈度直接查表得出,编写的程序极大地简化了优化设计的方法和计算过程。模型可以与现行设计规范相结合,优化方法极其实用和简便。
The optimization model using the latest code for seismic design of building( GB 50011—2010)( 2016 Edition)to minimize life-cycle cost structure. The first decision the optimal seismic intensity,and then the structural optimization of the design parameters. Structural damage at all levels are under the probability of intensity and structure of the basic site design intensity drawn directly in the chart. The computational program greatly simplifies the design optimization methods and calculation processes. The optimization model can combine existing seismic design code,so the optimization method is extremely practical and easy.
