排架计算中,当吊车起重量≥30吨时,上柱吊车荷载的内力应按柱顶不动铰的假定进行复核,这样显然增加了计算工作量。为了简化计算,本课题通过大量计算,在不同的外部条件下,按柱顶不动铰进行复核,获得上柱配筋值的增加系数K。有了K表,在工程设计中,排架按常规分析后,上柱配筋量直接乘以增加系数K就可以了,不必再按柱顶不动铰假定进行复核。即AG=K·AG_1式中AG——吊车荷载按柱顶不动铰假定
In the calculation of the pylon, when the crane has a weight of ≥ 30 tons, the internal force of the upper crane load should be rechecked on the assumption that the column top is not hinged, which obviously increases the calculation workload. In order to simplify the calculation, this subject through a large number of calculations, under different external conditions, according to the top of the column hinge recheck, to obtain the upper column reinforcement value increase factor K. With the K-table, in the engineering design, after the conventional analysis of the trusses, the amount of reinforcement in the upper column is multiplied directly by the increase factor K, and it is no longer necessary to review the column top without the hinge assumption. That is, AG=K·AG_1 Type AG—Crane Load According to Column Top Non-moving Hinge Assumption
