摘要

摘要: 为解决普通钢筋混凝土电力管道的电磁屏蔽问题,提出一种新型正弦波纹钢骨混凝土圆管。将圆管顶部受弯段作为研究对象,设计并制作了12根梁试件,开展了三点受弯加载试验。通过试验得到了梁试件的弯矩-挠度关系和破坏形态,试验结果表明梁受弯承载力与波纹钢骨的波长和波高呈反比,且与波纹钢骨的位置有关。采用ABAQUS建立了考虑波纹钢骨材料力学性能和混凝土损伤的精细数值模型,对波纹钢骨混凝土梁的受弯性能进行模拟,有限元分析得到的梁破坏形态和受弯承载力与试验结果吻合良好,验证了有限元模型的准确性。

Abstract: A novel type of sinusoidal corrugated steel-reinforced concrete circular pipe was proposed to present the solution to the electromagnetic shielding problem of ordinary reinforced concrete power pipelines. The segment at the top of circular pipe under bending was selected and studied, and a total of 12 beam specimens were designed and fabricated. Three-point bending tests were performed to acquire the relations between moment and deflection, as well as the failure modes of the beam specimens. It was revealed that the moment resistance of beam specimens decreased as the wavelength and wave height of the encased corrugated sheet increased, and the moment resistance was closely related to the position of the encased corrugated sheet. A fine numerical model accounting for the mechanical properties of encased corrugated sheet and the damage development of concrete was developed by using ABAQUS. The flexural performance of the tested corrugated steel reinforced concrete beams was carefully simulated, and it was shown that the numerically obtained failure modes and moment resistances were in good agreement with the experimental results, thus verifying the accuracy of the developed finite element (FE) model.
