［摘要］對砌體結(jié)構(gòu)安全鑒定中小墻垛存在受壓承載力不滿足規(guī)范要求的原因進(jìn)行分析，指出采用PKPM等軟件進(jìn)行砌體結(jié)構(gòu)受壓承載力計算時，按照洞口中線分配小墻垛和長墻段的荷載是不合理的。指出長度不大于620mm的墻體均可視為小墻垛，并給出了相應(yīng)的處理方法。通過實際砌體結(jié)構(gòu)墻體受壓承載力計算驗證，該處理方法能夠滿足評定的要求。

Abstract:The reasons for the compressive bearing capacity of small wall stacks in safety appraisal of masonry structure does not meet the requirements of the code were analyzed. It was pointed out that it is unreasonable to distribute the load of small wall stacks and long wall sections according to the central line of the opening, when using PKPM and other software to calculate the compressive bearing capacity of masonry structure. It was pointed out that the wall with the length less than 620mm can be regarded as small wall stacks, and the corresponding treatment methods were given. Through compressive bearing capacity calculation verification of the actual masonry structure wall, the processing method can meet the requirements of evaluation.
Keywords:masonry structure;compressive bearing capacity;small wall stack; safety appraisal
