[摘要]根据平截面假定和静力平衡条件，考虑砌体结构不同的应力-应变关系，推导出蒸压粉煤灰砌体柱受压承载力计算公式。同时利用本文推导的公式求出承载力理论值，再与试验数据进行比较，从数据的吻合度来验证本文提出的计算方法。依据《砌体结构设计规范》（GB 50003—2011）中的计算公式求出承载力理论值后，与试验数据进行比较，运用此规范所求的承载力理论值是偏大的。这样针对蒸压粉煤灰砌体柱，此规范方法所计算的受压承载力值被高估，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
