部分填充钢-混凝土组合柱整体稳定分析
|
摘要
研究采用厚实截面工字钢的部分填充钢-混凝土组合(PEC)柱构件在轴压和压弯作用下的整体稳定性能。利用ABAQUS有限元软件建立PEC柱模型,并对比文献中的实验数据以校核其正确性。应用该模型进行参数分析,考察纵向钢筋、翼缘系杆、截面高宽比等因素对PEC柱稳定极限承载力的影响。根据有限元计算结果选定了原用于纯钢构件的轴压稳定系数,并提出针对轴压和压弯PEC柱的整体稳定设计用公式。
A study was conducted to investigate the overall buckling behavior of partially encased composite(PEC) columns made of compact steel I-section under axial and eccentric loadings. A finite element model was set up to model the behavior of PEC columns and was validated by comparison with previous experimental data. This model is used to analyze the influence of parameters including longitudinal reinforcements, transverse links and section aspect ratios on the ultimate stability load of PEC columns. The overall stability factor of axially loaded PEC columns referring to axially compressive loaded steel members is selected through numerical computation by finite element analysis. The formulas for overall stability design of axial and eccentric compressions are proposed.
