矩形钢管混凝土柱压弯力学性能分析
|
摘要
为了研究矩形钢管混凝土柱的压弯力学性能以及进一步提高设计阶段矩形钢管混凝土柱压弯承载力的计算精度,在先前的压弯试验研究的基础上,利用有限元软件Abaqus建立了矩形钢管混凝土柱的有限元模型,与试验结果对比并进行了参数化分析,发现构件的抗弯刚度随截面尺寸的增大而增大,偏心率和长细比是影响构件承载力以及挠度发展的主要因素。此外,通过对于同一构件改变偏心距的方式,得到构件的荷载—弯矩曲线的有限元结果,将其与试验结果以及规范EC4、CECS159:2004、LRFD99中简化计算公式得到的荷载—弯矩曲线进行对比,分析得出:有限元和规范EC4、规范CECS159:2004的计算结果较为安全准确,而规范LRFD过于保守。再提取大量现有文献中的试验数据与上述规范中的轴压、纯弯、压弯承载力公式计算结果进行对比,提出针对不同影响因素合理选择较为适用的规范的建议。
In order to study the eccentric compression properties of concrete filled rectangular steel column and to further improve the calculation accuracy of the ultimate eccentric compression load,based on the previous research on eccentric compression test,the finite element model of concrete filled rectangular steel tube column is established by using the finite element software( Abaqus).The simulation results are compared with the experimental results,and the parametric analysis is carried out to study the influence of different factors on the compression-bending resistance. It is found that the flexural rigidity of the members increases with the increase of the section size,and the eccentricity and slenderness ratio are the main factors that affect the bearing capacity and deflection development of the members. In addition,by changing the eccentricity of the same component,the numerical N-M curves of the component are obtained. Compared with the test results and the N-Mcurves obtained from the simplified formulas of EC4,CECS159: 2004 and LRFD99,it is concluded that the calculation results of the finite element,the standard EC4 and the standard CECS159: 2004 are safer and more accurate,while those of the standard LRFD is too conservative. The experimental data from a large number of existing documents are compared with the calculation results of the axial compression, bending and eccentric compression capacity formulas in the aforementioned specifications. Some suggestions for reasonable selection of applicable standards for different factors are proposed.
