摘要
砌体结构的加固是1个较难的多指标决策问题,为科学准确地选择出最佳砌体结构加固方案,引入了组合赋权-TOPSIS法理论进行分析。笔者在建立了1套评价指标体系的基础上,将G1法计算得到的值与熵值法计算得到的值通过组合公式得出1个权重值,计算得出各个方案的欧式距离以及关联度,最终计算出各个方案的相对贴近度,并根据相对贴近度值的大小来推断各方案的好坏程度。本试验以河北农业大学水利楼为例阐述了组合赋权-TOPSIS法解决砌体结构加固方案的计算过程,最终证实组合赋权-TOPSIS法可在砌体结构加固方案优选过程中应用。
The reinforcement of masonry structure is a difficult multi-criteria decision-making problem. For the scientifically accurate selection of the best masonry structure reinforcement scheme, the combination weightingTOPSIS method theory is introduced for analysis. First of all, this research established a set of evaluation index system.Then, the value calculated by the G1 method and the value calculated by the entropy method were combined to obtain a weight value through a formula.Then we calculated the Euclidean distance, the correlation of each scheme, and the closeness of each scheme, based on which to infer the quality of each scheme.Taking the Water Conservancy Building of Hebei Agricultural University as an example, this research expounds the calculation process of the combined weighting-TOPSIS method to solve the masonry structure reinforcement scheme, and finally confirms the application of the combination weighting-TOPSIS method in the optimization process of the masonry structure reinforcement scheme.
