摘要:
为提高传统L形钢异形柱的整体稳定性及材料利用率,提出一种新型L形波形板钢异形柱,该柱由工字形钢、波形板及外侧翼板三部分构成。为研究该柱轴压性能及各部分截面参数的影响特征,设计6个模型,采用有限元软件ABAQUS进行弹性屈曲及非线性分析,研究各模型屈曲模式、荷载-位移曲线、破坏特征,以及整体稳定系数、极限荷载等关键性能指标变化率与截面参数变化率的关系; 将各模型整体稳定系数与现行《钢结构设计标准》中的柱构件轴压稳定系数曲线进行对比分析。结果表明:L形波形板钢异形柱屈曲模式均为弯扭屈曲; 各模型稳定系数均在b类柱构件轴压稳定系数曲线之上; 稳定承压性能随外侧翼板、工字形钢翼缘面积增大而增强,随工字形钢腹板面积增大而减弱。
Abstract:
In order to improve the overall stability and material utilization of traditional L-shaped steel column, a new type of L-shaped steel column with corrugated plate was proposed, which was composed of I-shaped steel, corrugated plate and outer flange plate three parts. In order to study the axial compressive performance of the column and the influence characteristics of various section parameters, 6 models were designed and elastic buckling and nonlinear analysis were carried out by finite element software ABAQUS. The buckling modes, load-displacement curves, failure characteristics of models, as well as the relationship between the changing rate of key performance indicators such as overall stability coefficient and ultimate load and the rate of change of section parameters were studied. The overall stability coefficient of each model was compared with column curves of the current Standard for Design of Steel Structures. The results show that the buckling modes of the L-shaped steel columns with corrugated plate are all flexural torsional buckling. The stability coefficients are all bigger than that of class b cross-section column curve. The compressive performance increases with the increase of the areas of the outer flange plate and I-shaped steel flange and weakens with the increase of I-shaped steel web area.
