摘要:
将混凝土内的钢筋模拟为能承受轴向力、抵抗弯曲变形的梁单元,在梁元节点位移服从平面单元位移场的基本假设下,应用虚功原理建立了单元内任意位置含钢筋梁元的钢筋混凝土平面组合单元模型.通过与现有钢筋混凝土平面单元模型比较,本模型更准确全面地反映了钢筋的力学性能,钢筋在平面单元内的位置不再有任何限制,混凝土和钢筋可以各自独立地进行网格划分,为单元离散提供了便利.
Abstract:
The steel bar in concrete is simulated as a beam element that can withstand axial force and resist bending deformation, and under the basic assumption that the displacement of the beam element node obeys the displacement field of the plane element, the model of reinforced concrete plane composite element containing reinforced concrete beam element at any position in the element is established by applying the principle of virtual work. Compared with the existing reinforced concrete planar element model, this model reflects the mechanical properties of the steel bar more accurately and comprehensively, the position of the steel bar in the planar element no longer has any limitation, and the concrete and steel bar can be meshed independently, which provides convenience for the discretization of the unit.
