Influences of rib stiffeners on hysteretic behavior of end-plate connections;

加勁肋對端板連接滯回性能的影響

L-joints without rib stiffener are semi-rigid connections.

采用簡化理論方法對L形圓管節點的強度和剛度進行了分析,橫向正應力的存在對節點域鋼管具有“捏合”作用,從而降低了節點的剛度和承載能力,無加勁肋的L形管節點屬于半剛性連接。

Among them, four end plates are reinforced with rib stiffeners, which are in alignment with beam webs, and constant axial compression force is applied at the end of seven columns during the test.

為了研究鋼框架中梁柱端板連接節點的滯回性能,本文進行了8個節點試件的循環加載試驗,其中有7個試件的柱端施加了軸向壓力,4個端板設置了加勁肋。

Static behavior analysis of top and seat angle with stiffener connection beam-to-column joints;

帶加勁肋的頂底角鋼連接梁柱節點的靜力性能分析

The stiffeners that were mounted in compression zone can decrea.

發現:端板厚度對節點的初始轉動剛度影響較大,載荷比對轉角的影響較大;設置承壓加勁肋可明顯減小節點域內的塑性應變,改善柱腹板的受力狀態,提高柱穩定性,從而保證鋼框架整體的穩定性。

FEA models were established to make analysis on the influence of wall panel,horizontal rib stiffener and inside steadying bar to mechanics properties of one typical flue gas duct in fuel electric plant.

通過建立火力發電廠鋼煙道的有限元計算模型,對煙道壁板、煙道橫向加勁肋和有無內支撐對鋼煙道力學性能的影響進行了計算分析,并對設置縱向加勁肋的作用進行了深入討論。

During the analysis, two parameter was considered:the depth and length of stiffening rib.

利用有限元軟件分析輸電鐵塔8個地腳螺栓塔腳板受力過程,討論其破壞機理、破壞準則,介紹了加勁肋厚度、長度等參數變化對其承載力的影響,在此基礎上提出一些設計建議。

The paper analyses the stability of rib slab on method of energy,the formula of longitudinal critical force is deduced,and rational arrangement of stiffening rib is discussed.

利用能量法分析了加肋平板的穩定問題 ,推導了縱向臨界力的計算公式 ,并探討加勁肋的合理布置 。

The steel silo wall is a typical cylindrical shell structure which is very sensitive to the boundary conditions, so setting up stiffening rib on the silo wall can improve the stability effectively, but it is the lack of related research.

再采用數值分析方法,包括線性特征值屈曲分析、幾何非線性分析及幾何、材料雙重非線性分析,研究了不同加勁肋對鋼筒倉倉壁穩定性能的影響。
