［摘要］搜集了國內(nèi)外151片配筋砌塊砌體剪力墻受剪試驗的試驗數(shù)據(jù)，并建立了數(shù)據(jù)庫，以此為基礎(chǔ)對《砌體結(jié)構(gòu)設(shè)計規(guī)范》（GB 50003—2011）中的配筋砌塊砌體剪力墻斜截面受剪承載力的設(shè)計公式進行可靠度分析。結(jié)果表明，該公式具有較高的準確度，并且滿足《工程結(jié)構(gòu)可靠性設(shè)計統(tǒng)一標準》（GB 50153—2008）關(guān)于可靠度的要求。利用數(shù)據(jù)庫對
配筋砌塊砌體剪力墻斜截面受剪承載力平均值計算公式進行非線性擬合分析，建議對該平均值公式進行系數(shù)上的微調(diào)，調(diào)整后的公式具有更高的準確度。根據(jù)調(diào)整后的公式提出了建議設(shè)計公式，通過驗算證明了建議設(shè)計公式滿足相關(guān)規(guī)范中可靠度要求。［關(guān)鍵詞］試驗數(shù)據(jù); 砌體剪力墻; 受剪承載力; 砌體規(guī)范; 公式檢驗; 可靠度分析中圖分類號：TU375 文獻標識碼：A 文章編號：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
