摘要
随着人们对大型复杂工程抗震设计要求的不断提高,基于性能的抗震设计方法将成为未来工程抗震领域的新趋势。该方法综合考虑地震风险水平、项目投资能力、建筑的功能和重要性等因素,采取不同的抗震结构体系和方法来分析、评估结构的抗震能力。Pushover分析法、增量动力分析法、蚁群优化法等算法的应用,使基于性能的钢结构抗震设计更加精确合理。
As the advancing of seismic design requirements of large complex project,the performance-based seismic design method will become the new tendency in the field of future anti-seismic engineering. This method comprehensively considers the principal elements such as earthquake risk level,project investment capacity,function and materiality of building,etc. It analyzes and assesses the seismic resistance of structures by taking different seismic structure system. The application of algorithms such as Pushover Analysis,Incremental Dynamic Analysis,Ant Colony Optimization makes performance-based seismic design method of steel structure more accurate and reasonable.
