T形截面砖柱排架在设计中甚为常见,此种方案经常是采用刚性的条形基础。在计算砖柱强度及条形基础的大小时,一般习惯于只用一个方向弯矩的荷载组合进行核算,忽视了反向弯矩的危险性,致使结构安全系数不能满足规范要求,而设计者却往往误以为一向的安全度已够,不用验算另一向。 T-section brick pillars are common in design, and this type of solution is often based on rigid strips. When calculating the strength of a brick column and the size of a strip foundation, it is generally used to account for load combinations with only one direction of bending moments, ignoring the danger of reverse bending moments, so that the structural safety factor cannot meet the specification requirements, and the designer However, they often mistakenly believe that the safety has always been enough, do not check the other direction.
