以某大型转炉炼钢厂房为研究对象,建立三维有限元整体模型和框排架平面模型进行抗震分析,通过对比研究,提出了一种用特殊的面外弹簧修正的框排架平面计算模型,实现了从空间抗震分析到平面抗震分析的简化。 Taking a large-scale converter steelmaking plant as the research object, a three-dimensional finite element model and a box-frame plane model are established for seismic analysis. Based on the comparative study, a plane frame calculation model with a special out-of-plane spring correction is proposed. It realizes the simplification of seismic analysis from space to plane seismic analysis.
