摘要
基于典型的砌体结构工程案例,将结构层数和砂浆强度作为控制变量,运用三种加固方案开展变参数建模计算,得出变参数模型下楼层的综合抗震能力指数差值及加固费用,建立砌体结构加固效费比模型。依据所建立的砌体结构加固效费比模型,综合考虑经济、技术、功能、效果对加固方案的影响,结合组合赋权-TOPSIS算法,建立了一套基于效费比的砌体结构抗震加固优选方法。结果表明:提出的优选方法,能更有效地融合定量指标与定性指标,科学、合理地确定最优加固方案。
Based on a typical masonry structure project,the number of structural floors and mortar strength are taken as control variables,and three reinforcement schemes are used to perform variable parameter modeling calculations,which results in the difference of comprehensive seismic capacity indices of floors and reinforcement costs of variable parameter models,and establishes a masonry structure reinforcement cost-effectiveness ratio model.According to the established masonry structural reinforcement cost-effectiveness ratio model,considering the economic,technological,functional,and effectiveness impacts of the reinforcement program in an integrated manner,combined with the combined assignment-TOPSIS algorithm,a set of masonry structural seismic reinforcement optimization methods based on cost-effectiveness ratio is established.The results show that the proposed optimization method can better combine quantitative and qualitative indicators to give the optimal reinforcement scheme in a scientific and reasonable way.
