【摘要】：本文對(duì)中國(guó)、美國(guó)和新西蘭三國(guó)現(xiàn)行的砌體規(guī)范中有關(guān)配筋砌塊砌體剪力墻受剪承載力的設(shè)計(jì)公式進(jìn)行了橫向的對(duì)比,對(duì)比發(fā)現(xiàn),中國(guó)規(guī)范的設(shè)計(jì)公式相比美國(guó)和新西蘭規(guī)范的設(shè)計(jì)公式在考慮砌體對(duì)墻體受剪承載力的貢獻(xiàn)時(shí)更加保守,而在考慮水平鋼筋對(duì)墻體受剪承載力的貢獻(xiàn)有所高估。本文收集了國(guó)內(nèi)外有關(guān)配筋砌塊砌體剪力墻受剪試驗(yàn)的試驗(yàn)數(shù)據(jù),建立了一個(gè)共計(jì)118片試驗(yàn)墻體的數(shù)據(jù)庫(kù)。利用數(shù)據(jù)庫(kù)對(duì)三國(guó)規(guī)范的設(shè)計(jì)公式進(jìn)行偏差計(jì)算和可靠度計(jì)算,并進(jìn)行對(duì)比分析。結(jié)果表明,中國(guó)規(guī)范的設(shè)計(jì)公式在計(jì)算體對(duì)墻體受剪承載力的貢獻(xiàn)時(shí)過于保守,而在計(jì)算水平鋼筋對(duì)墻體受剪承載力的貢獻(xiàn)時(shí)略有高估。從總體看,三國(guó)規(guī)范的設(shè)計(jì)公式均滿足可靠度的要求,其中中國(guó)規(guī)范設(shè)計(jì)公式留有的安全裕度最多,設(shè)計(jì)偏于保守,而美國(guó)規(guī)范的設(shè)計(jì)公式較為合理,新西蘭規(guī)范的設(shè)計(jì)公式介于兩者之間。參考對(duì)比分析的結(jié)果并利用數(shù)據(jù)庫(kù)進(jìn)行擬合分析,對(duì)中國(guó)規(guī)范的平均值計(jì)算公式的相關(guān)參數(shù)進(jìn)行調(diào)整,對(duì)修改后的平均值計(jì)算公式進(jìn)行偏差計(jì)算并對(duì)比原平均值計(jì)算公式的偏差計(jì)算結(jié)果。對(duì)比發(fā)現(xiàn)修改后的平均值計(jì)算公式能夠更加準(zhǔn)確、合理的反映配筋砌塊砌體剪力墻受剪承載力�；谛薷暮蟮钠骄涤�(jì)算公式建立一個(gè)新的設(shè)計(jì)公式,通過偏差計(jì)算和可靠度計(jì)算與原設(shè)計(jì)公式做對(duì)比。結(jié)果表明新設(shè)計(jì)公式在可靠度比原設(shè)計(jì)公式可靠度有所減少(仍滿足規(guī)范可靠度的要求)的情況下,在一定程度上解決了原設(shè)計(jì)公式在計(jì)算砌塊對(duì)墻體受剪承載力的貢獻(xiàn)時(shí)偏于保守,而在計(jì)算水平鋼筋對(duì)墻體受剪承載力的貢獻(xiàn)時(shí)略有高估的問題。使其在設(shè)計(jì)上變得更為合理。
[Abstract]:In this paper, the design formulas of shear capacity of reinforced block masonry shear walls in the current masonry codes of China, the United States and New Zealand are compared horizontally. The design formula of the Chinese code is more conservative than that of the American and New Zealand codes in considering the contribution of masonry to the shear bearing capacity of the wall, while the contribution of horizontal reinforcement to the shear bearing capacity of the wall is overestimated. In this paper, the experimental data of shear test of reinforced block masonry shear wall at home and abroad are collected, and a database of 118 test walls is established. The deviation calculation and reliability calculation of the design formulas of the three countries' specifications are carried out by using the database, and the results are compared and analyzed. The results show that the design formula of the Chinese code is too conservative in calculating the contribution of the body to the shear bearing capacity of the wall, but slightly overestimated in the calculation of the contribution of horizontal reinforcement to the shear capacity of the wall. On the whole, the design formulas of the codes of the three countries all meet the requirements of reliability. The Chinese code design formula has the most safety margin and the design is conservative, while the design formula of the American code is more reasonable. The design formula of the New Zealand Code is somewhere in between. Referring to the results of comparative analysis and using the database for fitting analysis, the relevant parameters of the formula for calculating the average value of the Chinese standard are adjusted. The deviation calculation of the modified average value calculation formula is carried out and the results of deviation calculation of the original average value calculation formula are compared. It is found that the modified formula can reflect the shear capacity of reinforced block masonry shear wall more accurately and reasonably. A new design formula is established based on the modified formula of mean value. The deviation calculation and reliability calculation are compared with the original design formula. The results show that when the reliability of the new design formula is less than that of the original design formula, the reliability of the new design formula still meets the requirements of the specification reliability. To some extent, the original design formula is conservative in calculating the contribution of block to shear capacity of wall, but slightly overestimated in calculating the contribution of horizontal reinforcement to shear capacity of wall. Make it more reasonable in design.
