摘要:
基于提出的变形等价原理定义了广义损伤变量,给出了“材料、截面、构件、楼层、结构”多层次刚度损伤的计算方法,各层次的刚度损伤可由材料刚度损伤积分求得。利用ABAQUS软件建立了“单跨12层钢筋混凝土标准框架模型试验”的计算模型,计算分析了结构各层次的刚度损伤演化过程。计算结果表明:在El Centro地震波三向作用下,结构的3~7层损伤严重且为梁铰破坏模式,第8层损伤严重且为柱铰破坏模式; 构件端部截面破坏严重,3~8层构件端部截面的受压区混凝土被压碎。数值分析结果与试验结果基本一致,说明多层次刚度损伤演化分析能够正确反映结构破坏的内在机制。
Abstract:
The generalized damage variable is defined based on a deformation equivalent principle. Stiffness damage of each level can be calculated by stiffness damage integration from material-level. This method can be used to evaluate the stiffness damage for material, section, member, story, and structure. The numerical simulation model of the “single span 12-story RC frame model test” was built by using the software ABAQUS. Multi-level stiffness damage evolution of this model was analyzed. The numerical results show that under El Centro seismic motion, Story 3-7 were damaged seriously with the beam-hinge failure mode; story 8 was damaged seriously with the column-hinge failure mode; the end sections of the columns and beams of story 3-8 were damaged seriously with concrete crushing. The accordance of the numerical and experimental results shows the multi-level stiffness damage evolution analysis can reflect the structural inhere damage mechanism.
