摘要
为最大限度提升受损既有建筑的抗震性能,科学合理地确定最佳抗震加固方案,针对抗震加固的目的和要求,建立抗震加固综合评价指标体系,采用群决策相对熵集结法与改进熵权法组合的方式求解指标权重。构建灰色关联改进的TOPSIS模型,以一种新的相对贴近度形式决策出最佳的抗震加固方案。最后通过工程实例的计算分析,佐证方法的适用性。研究结果表明:基于组合赋权灰色关联改进TOPSIS法适用于既有建筑抗震加固方案的优选,具有较高的可行性与合理性。
In order to maximize the seismic performance of damaged existing buildings,the best seismic reinforcement scheme is scientifically and rationally determined.On the basis of practical projects and literature review,aiming at the purpose and requirements of seismic reinforcement,a comprehensive evaluation index system of seismic reinforcement is established,and the combination of group decision-making relative entropy aggregation method and improved entropy weight method is used to solve the index weights.The improved TOPSIS model based on grey relational is constructed to determine the best seismic reinforcement scheme in a new form of relative closeness.Finally,the applicability of the method is proved through the calculation and analysis of engineering examples.The research results show that the improved TOPSIS method based on the combined weighting gray relational is applicable to the optimization of seismic reinforcement schemes for existing buildings,and has high feasibility and rationality.
