【摘要】 本文对钢筋混凝土迭合梁在均布荷载下的抗剪性能进行了试验研究和理论分析。 首先介绍了迭合梁的试验过程和结果分析,分析表明,迭合梁的受力性能与相应的整体梁比较具有较大的不同。然后,采用有限元非线性分析方法对均布荷载下的整体梁和迭合梁的抗剪强度进行了分析,提出了抗剪强度的计算公式,并和试验结果进行了比较。更多还原

【Abstract】 This paper presents an experimental and analytical study of shear behavior of reinforced conerete composite beams with two-stage uniformly distributed loadling.The test results indicate that the composite beams have some drfferenles in shear behavior compared with general integral beams. Analyses are made on shear strength of eintegral and composite beams subiected to distributed loading by the nonlinear finite element method in IBM-PC. The formula of shear strength are given and they are good agreeable with the tost results.更多还原
