中文摘要:
      建筑砌体结构抗震性能评估,对建筑结构安全的稳定性至关重要。本文从四个方面分析建筑砌体结构抗震性能提升的条件,根据建筑结构的抗震性影响因素,评估抗震能力。构建建筑砌体结构抗震性能的评估BIM指标体系;利用BIM模型中的三角模糊数,定量计算建筑砌体结构抗震性能指标的模糊判断矩阵,得到建筑砌体结构的三角模糊数值,分析筑砌体结构抗震性能指标的单排序情况,结合对建筑砌体结构抗震性能评估体系指标权重系数和单项得分的计算,实现基于BIM的建筑砌体结构抗震性能评估。结合模拟建筑实例分析,利用建筑结构倒塌概率测试建筑砌体结构的抗震性能,并利用评估结果与实际评估结果的拟合度测试提出方法的准确性。实例结果证明,能够准确的得到抗震性能的评估结果。
英文摘要:
      To evaluate the seismic performance of masonry structures based on Building Information Modeling (BIM), we (1) analyzed the requirements for seismic performance improvement of masonry structures from four aspects, (2) calculated the seismic capacity with the strength and ductility of such a building structure, and (3) constructed an evaluation index system of seismic performance for masonry structures. On this basis, a fuzzy judgment matrix of the seismic performance indexes of masonry structures was quantitatively calculated using triangular fuzzy numbers, and the single-level sequence of seismic performance indexes was analyzed by calculating the fuzzy comprehensive value of seismic performance. Combined with calculation of the index weight coefficient and the single-item score of the seismic performance evaluation system, a BIM-based seismic performance evaluation of masonry structures was ultimately realized. Combined with analysis of a simulated project, the seismic performance of a masonry structure was tested with the collapse probability of the structure, while the accuracy of the proposed method was tested by the fitting degree of evaluated results and actual results. The results showed that the proposed method not only has good seismic performance, it can also accurately obtain the seismic performance evaluation results of masonry structures.
