摘要:

以一座9层钢支撑框架结构作为研究对象,采用新一代基于性能的抗震评价理论对其进行了地震损失风险分析,讨论了由商业办公、零售、酒店公寓3种不同主流业态的7个建筑组合方案的地震损失差异。同时,基于遗传算法提出考虑地震损失风险和决策者主观意愿的最优业态组合决策方法。结果表明:该建筑结构的倒塌风险较低,50年内倒塌概率约为0.64%。选择不同业态组合方案明显影响建筑地震损失,最大相对损失差距约为20%。

Abstract:

Currently,most attentions was devoted to assessing seismic losses for newly-built or existing building structures with certain structural design schemes.Few studies were performed to take the seismic-loss estimation into account the architectural design of buildings especially for the architectural function arrangement.In this study,a nine-story,concentrically-braced frame structure was focused.The new generation of performance-based earthquake engineering theory was used to estimate seismic-loss risks.The differences in seismic-loss results for the considered seven building functional schemes that consist of commercial office,retail and apartment were discussed.Subsequently,an optimal decision approach based on the genetic algorithm was developed for determining architectural functions of buildings involving seismic-loss risk and the decision-maker’s initiative.The results show that the risk of the structure’s collapse in 50 years is as low as 0.64%.The selection of architectural function scheme of buildings has considerable effects on the economic losses under the seismic action.The largest relative difference can be up to 20%.
