摘要
论述了塔式容器考虑高振型时的自振周期和地震弯矩等的详细计算方法,同时结合JB/T4710—2005《钢制塔式容器》、NB/T 47041—2014《塔式容器》中[例题3]等直径浮阀塔例题做了详细的说明,并在此基础上开发了一套计算塔式容器高振型地震、风荷载的计算程序。
In this article, the method of calculating natural vibration period in high order mode and seismic moment for tower was described. Combined with JB/T 4710—2005 ＂Steel Vertical Vessel Support with Skirt＂ and NB/T 47041—2014 ＂Vertical Vessel Support with Skirt＂, the example of equal-diameter tower with floating valves demonstrated in the standard was explained in detail, based on which a program for calculating seismic and wind load in high order mode for tower was developed.
