［摘要］搜集了国内外151片配筋砌块砌体剪力墙受剪试验的试验数据，并建立了数据库，以此为基础对《砌体结构设计规范》（GB 50003—2011）中的配筋砌块砌体剪力墙斜截面受剪承载力的设计公式进行可靠度分析。结果表明，该公式具有较高的准确度，并且满足《工程结构可靠性设计统一标准》（GB 50153—2008）关于可靠度的要求。利用数据库对
配筋砌块砌体剪力墙斜截面受剪承载力平均值计算公式进行非线性拟合分析，建议对该平均值公式进行系数上的微调，调整后的公式具有更高的准确度。根据调整后的公式提出了建议设计公式，通过验算证明了建议设计公式满足相关规范中可靠度要求。［关键词］试验数据; 砌体剪力墙; 受剪承载力; 砌体规范; 公式检验; 可靠度分析中图分类号：TU375 文献标识码：A 文章编号：1002-848X(2015)12-009605
Reliability analysis of shear bearing capacity formula of reinforced concrete masonry shear wall based on databaseHuang Liang, Huang Kai, Shi Chuxian(School of Civil Engineering, Hunan University, Changsha 410082, China)Abstract: The shear test data of 151 pieces of reinforced concrete masonry shear wall were collected from home and abroad and the database was set up. The reliability of shear bearing capacity formula of oblique section of reinforced concrete masonry shear wall in Code for design of masonry structures（GB 50003—2011）was analyzed based on the database. The results show that the formula has high accuracy and can meet the reliability requirements of Unified standard for reliability design of engineering structures（GB 50153—2008）. The nonlinear fitting analysis was carried out on the average value formula based of oblique section of reinforced concrete masonry shear wall on the database. It recommended that the coefficient in the average value formula was adjusted finely and the adjusted formula had a higher accuracy. According to the adjusted formula, a design formula was proposed, and calculations proved that the proposed design formula can meet the reliability requirements in relative specification.Keywords: test data; masonry shear wall; shear bearing capacity; masonry code; formula verification; reliability analysis
