[摘要] 大型煉鐵高爐承受的荷載大且不對稱，它不同于一般的框架結(jié)構(gòu)可簡單地采用平面分析計(jì)算，空間作用不可忽視。采用SAP2000有限元軟件，對高爐框架系統(tǒng)、粗煤氣系統(tǒng)及重力除塵器系統(tǒng)進(jìn)行整體三維空間建模，采用一階彈性分析方法，真實(shí)反映結(jié)構(gòu)的受力狀況，驗(yàn)算承載力極限狀態(tài)和正常使用極限狀態(tài)。

Abstract: Because of the large and asymmetric load it supports,the large-scale blast fumace is different from the general framework which can be easily calculated with plane analysis method, its space action can not be ignored. Make whole three-dimensional model for the blast furnace, the raw gas system and the gravity dust remover with SAP2000, reflect the real force status of the structure by using first-order elastic analysis method, check the bearing capacity limit state and normal use limit state.
Keywords: blast fumace; spatial steel structure; first order elastic analysis; overall calculation
