基于钢板屈曲分析的双钢板-混凝土组合剪力墙轴压承载力计算方法
|
摘要
为了考虑钢板屈曲对双钢板-混凝土组合(DSCC)剪力墙的轴压承载力的影响,该文首先以4个组合墙的轴压试验为基础,采用ABAQUS建立DSCC剪力墙的有限元模型。模型中混凝土采用实体单元,钢板采用壳单元,剪力连接件采用非线性弹簧单元SpringA,并考虑了材料非线性和钢板初始缺陷。在验证有限元模型后,研究了不同参数对钢板屈曲的影响,得到了钢板屈曲应力的计算公式。分析结果表明:当钢板出现局部横向贯通屈曲时,破坏模式为屈曲位置的混凝土压碎;当钢板未发生屈曲时,破坏模式为钢板屈服;墙侧面钢板宽度较小时,侧面钢板不会发生屈曲。最后,基于钢板屈曲分析以及构件极限状态下的应力状态分析,提出了新的DSCC剪力墙的轴压承载力计算方法,引入了钢板屈曲的影响。结构表明:对比规范JGJ/T380―2015采用的计算公式,该文提出的计算方法具有更高的精度和稳定性,可用于DSCC剪力墙的深入研究以及工程设计。
To investigate the effect of steel plate buckling on the axial compression bearing capacities of double steel-concrete composite(DSCC) shear walls, the finite element models were built using ABAQUS in accordance with four axial tests of DSCC shear walls. In the numerical models, concrete was modeled with solid elements, steel plate with shell element and shear connectors with nonlinear spring element Spring A. Moreover, the nonlinear behavior of materials and initial imperfection of steel plates were taken into account in the analysis. After the validation of numerical models, the effects of different parameters on the local buckling of steel plates were investigated, and the formula to calculate the buckling stress was obtained. The numerical results indicate that: if the local buckling goes through the transverse section of steel wall plates, the failure mode is concrete crushing at the buckling position, and if no buckling occurs, the failure mode is yielding in the steel plates; when the width of side steel plates is small, no buckling occurs at the side plates. Based on the buckling analysis and ultimate stress state analysis, a new approach was proposed to compute the axial compression bearing capacity of DSCC shear walls with the consideration of steel plate buckling. The results show that: compared with the calculation formula in the standard JGJ/T 380—2015, the proposed approach improves the accuracy and stability in estimating the axial bearing capacity and can be used for further research and engineering practice of DSCC shear walls.
