采用纤维梁单元分析钢-混凝土组合结构地震反应的应用
|
摘要
将用于钢-混凝土组合结构地震反应分析的纤维梁单元应用于各种类型构件的非线性分析中,包括普通钢筋混凝土构件(钢筋混凝土梁、钢筋混凝土柱和钢筋混凝土受弯剪力墙)、钢-混凝土组合梁构件(承受正、负弯矩的简支组合梁、连续组合梁和往复荷载作用下的组合梁)以及钢管混凝土构件(圆形、方形以及矩形轴心受压短柱构件、纯弯构件、压弯构件和往复荷载作用下的压弯构件),数值模拟结果和试验结果均吻合良好,证明了该模型具有良好的精度以及广泛的适用性。通过对关键截面关键纤维的应力-应变发展过程进行分析,对这些构件的内在受力机理和破坏规律进行了深入的讨论。经过验证可知,开发的纤维梁单元不仅能充分兼顾准确性、通用性以及高效性,同时还具备求解速度快、数值稳定性好以及前后处理强大方便的特点,为组合结构体系的地震反应分析提供了可靠的手段。
This paper presents the application of the proposed fiber beam element in the companian paper used for seismic response analysis of steel-concrete composite structures in the nonlinear analysis of various members,including ordinary reinforced concrete members(reinforced concrete beam,column and bending shear wall),steel-concrete composite beam members(simply supported composite beams under sagging and hogging moments,continuous composite beams,and composite beams under cyclic loading),and concrete filled steel tubular members(short column members under uniaxial compressive force,pure bending members and beam-column members subjected to static and cyclic loadings,with circular,square and rectangular sections).Good correlations between numerical and experimental results demonstrate that the proposed model provides good accuracy and broad applicability.Based on the analysis of stress-strain history of critical fibers at critical sections,the intrinsic mechanisms of these members are discussed intensively.The proposed fiber beam element provides a reliable and powerful tool for seismic response analysis of steel-concrete composite structures due to its accuracy,broad applicability,efficiency,rapid and stable numerical solution,as well as powerful and convenient pre-processing and post-processing,which are fully verified in this paper.
