[摘要]根據(jù)平截面假定和靜力平衡條件，考慮砌體結(jié)構(gòu)不同的應(yīng)力-應(yīng)變關(guān)系，推導(dǎo)出蒸壓粉煤灰砌體柱受壓承載力計(jì)算公式。同時(shí)利用本文推導(dǎo)的公式求出承載力理論值，再與試驗(yàn)數(shù)據(jù)進(jìn)行比較，從數(shù)據(jù)的吻合度來驗(yàn)證本文提出的計(jì)算方法。依據(jù)《砌體結(jié)構(gòu)設(shè)計(jì)規(guī)范》（GB 50003—2011）中的計(jì)算公式求出承載力理論值后，與試驗(yàn)數(shù)據(jù)進(jìn)行比較，運(yùn)用此規(guī)范所求的承載力理論值是偏大的。這樣針對(duì)蒸壓粉煤灰砌體柱，此規(guī)范方法所計(jì)算的受壓承載力值被高估，造成不安全。

Abstract: According to the assumption of plain section and equilibrium of static force, and considering different stress-strain relations of masonry structure, these formulas of the compressive bearing capacity of autoclaved flyash-lime brick column was deduced. At the same time, using the formula is deduced to calculate the theoretical value of bearing capacity, and then comparing the theoretical value with the experimental data, evaluating the method through checking the goodness fit between experimental data and the method selected. When compared theoretical value calculated according to code for design of masonry structures (GB 50003—2011) with experimental data, it was found that the theoretical date is larger than experimental data. So the compression capacity of autoclaved flyash-lime brick column based on the method provided by code is overestimated, which will lead insecurity.
Keywords: autocalved flyash-lime; masonry structure; compressive bearing capacity; stress-strain relation
