钢筋混凝土T梁受弯性能试验与数值模拟研究OA
Study on the Bending Performance Test and Numerical Simulation of Reinforced Concrete T-Beams
为了研究钢筋混凝土T梁的受弯性能,笔者设计了全长 3.6 m的T梁试验模型,采用模型试验与有限元分析方法开展研究.研究结果表明,混凝土T梁的受弯破坏模式与混凝土矩形梁不同,表现为主钢筋屈服、荷载不再增长;T梁破坏时,受压区混凝土已经进入塑性阶段,但是并未达到极限压应变;采用非线性有限元分析得到的受弯破坏模式、荷载-变形曲线与试验测试结果吻合较好,极限荷载模拟值与试验值的相对误差为 4.52%,文中采用的有限元模拟方法能够准确模拟钢筋混凝土T梁的受弯行为.
To investigate the bending performance of reinforced concrete T-beams,a 3.6-meter-long T-beam experimental model was designed and analyzed by using both model testing and finite element analysis techniques.The findings indicate that the bending failure mode of concrete T-beams differs from that of concrete rectangular beams,primarily due to steel bars yielding and the absence of further load increase.When the T-beam is damaged,the concrete in the compression…查看全部>>
