摘要
NB/T 47041—2014《塔式容器》中有裙座自支撑金属制塔器的计算方法,对其他支撑形式塔器没有给出明确的计算方法。针对此问题,通过对塔体受力特点的分析及钢制设备抗震设计的分析研究,确定了框架中塔器的自振周期、地震影响系数,并进行了载荷计算和应力评判。
There is just the method of calculation about steel vertical vessels supported by skirt in NB/T47041 2014,Vertical Vessels Supported by Skirt, and others are not described in it. According to the analysis of the mechanics performance about the columns not in the standard and research of seismic design about the steel body, the natural frequency and influence coefficient of the frame tower device are confirmed, and the loading capability and stress assessment are calcu lated.
