钢筒仓地震作用计算方法研究与分析
|
摘要
介绍美国、欧洲和我国钢筒仓设计规范对钢筒仓地震作用计算方法,并采用3本规范进行实例计算并相互比较。计算结果表明:我国规范计算结果偏于保守,我国规范与美国规范计算仓壁应力计算最大差异为15%~43%,位移差异为:11%~43%,按我国规范与美国规范计算钢筒仓加强筋应力最大差异为:10%~24%,位移差异11%~41%。我国GB 50322-2001《粮食钢板筒仓设计规范》正在修订中,本结果可为正在修订的设计规范提供参考。
The present paper introduced the calculation methods of steel silo under seismic load,which spicified by the America,the European and the Chinese silo codes.The three steel silo codes were taken to calculate the same steel silo structrue,the result indicated that the results by the Chinese code was conservative as compared with the other two steel soil codes.The calculation result showed that the maximum error in the stress calculation of the silo wall with the Chinese code and the American code was in the range of 15% to 43%,the displ acement error was 11% to 43%.The maximum error in the stress calsulation of the silo rebar was in range of 10% to 24%,the displacement error was 11% to 41%.The results may be a reference for revision of the grain steel silo code in China.
