摘要:
基于不同构造形式的框支密肋复合板结构低周反复加载试验,依据Park退化参数滞回规则,采用非线性程序IDARC建立结构计算模型,并进行加载过程滞回曲线和骨架曲线计算值与试验值对比分析,以验证模型的正确性.同时,依据方差分析法,对框支斜交肋格复合墙板构件关键部位内力和整体结构最大转角值影响因素进行显著性分析.运用Abaqus程序建立合理的墙板模型,给出不同受力状态下随墙板高度变化的位移曲线,得到框支正交、斜交肋格墙板分别偏于弯剪型和剪切型变形的结论.不同位置斜交肋杆的轴向应变及杆间作用产生的内力比较结果表明,结构具有明显的桁架特征,杆间作用对肋杆端部弯矩和轴力影响较小,杆件以轴向变形为主.
Abstract:
Based on the experiments of low-cyclic loading applied to the frame-supported multi-ribbed composite slab structures(FSMRC slab structures)with different forms, the calculated model was established incorporated in the nonlinear program IDARC by the hysteretic rules of Park degradation-parameter. The computing and test results of the hysteretic curve and the framework curve of the specimens during loading were compared and analyzed to verify the correctness of the established model. Moreover, the influence factors for the key part internal-force and the massive structural maximum angle of the frame-supported inclined-grid composite slab structure were analyzed by using the variance analysis. Besides, a reasonable slab model was established by using Abaqus, and the slab displacement-curves with the height under different loading conditions were obtained, so the frame-supported diagonal-grid, inclined-grid slabs delivered bending-shear and shear deformations, respectively. The comparison results of the axial-strain and internal forces caused by rib-effect of inclined-rib in different locations show that the structure presents an obvious truss-characteristic. Moreover, the influence of the rib-effect on the bending moment and the axial force of the diagonal-rid is small, and the main deformation of the diagonal-rid is axial deformation.
