高强钢筋混凝土连续梁受弯性能的试验研究和有限元分析
Experimental Study and FEM Analyses of the Flexural Behavior of the Reinforced Concrete Continuous Beam with High-strength Steel Bar
摘要
Abstract
The flexural behavior of two reinforced concrete continuous beams with HRB500 bars and one RC continuous beam with HRB335 bars was experimentally studied.And the numerical analysis was also conducted by using the FEM software.Test results indicated that the crack progression,the sectional strain distribution,the sequence of plastic hinges and the failure mode were almost the same for all three specimens. But the yielding load at the midspan,the yielding load at the mid-support,the ultimate load and the ductility factor of RC continuous beams with high-strength steel bars had a 28.7%,22.8%,30% and 8.1% increase respectively than that of RC continuous beam with normal-strength steel bars.The predictions of finite element analysis were in good agreement with the test results and can satisfy the engineering use requirement.关键词
