摘要:
为了研究钢板-混凝土组合加固钢筋混凝土T梁在静载作用下的抗弯性能,对带损伤的2片混凝土T梁组合加固后进行了抗弯承载力试验,得到了构件破坏时的极限抗弯承载力以及受力特性,揭示了钢板-混凝土组合加固钢筋混凝土T梁的弯曲破坏机理; 建立了钢板-混凝土组合加固钢筋混凝土T梁的有限元模型,并进行了非线性静力计算。结果表明:考虑材料非线性的静力计算结果与试验结果吻合良好; 采用塑性分析方法建立的试验梁极限抗弯承载力简化计算公式的计算结果与试验结果吻合良好。
Abstract:
In order to study the bending behavior of steel plate and concrete composite strengthening T-beam under static loads, bending capacity experiments of two damaged RC T-beams with steel plate and concrete composite strengthening(SPCCS)were carried out, and the ultimate bending capacity and mechanical behavior of the specimen were obtained, and the flexural failure mechanism of reinforced concrete(RC)T-beams with SPCCS was summarized. Then, a finite element model of RC T-beams with SPCCS was established, furthermore, the nonlinear static calculation was presented. Results show that the numerical results of nonlinear static analysis are in good agreement with the experiment results. The ultimate bending capacity can be calculated by plastic analysis method, it can be illustrated that the calculation results are in good accordance with the experiment results.
