| 摘 要： | 通过4个不同钢纤维体积率的钢筋混凝土连梁在低周反复荷载作用下的试验,测试了连梁在低周反复荷载作用下钢筋应变和侧向位移,分析了钢纤维对连梁中钢筋应变和侧向位移的影响规律.研究结果表明:钢纤维对连梁的纵向钢筋应变、箍筋应变和侧向位移影响明显;随着钢纤维体积率的增大,钢筋的极限应变和连梁的极限位移都显著增大.

| Abstract: | Through the test research on the 4 reinforced concrete coupling beams with different volume fractions of steel fibers under the low cyclic reverse load,the strain of reinforcements and the horizontal displacement of the coupling beams with different volume fractions of steel fibers were tested,and the effects of different volume fractions of steel fibers on the strain of reinforcements and the horizontal displacements of the reinforced concrete coupling beams were analyzed.The results indicated that the effects of volume fractions of steel fibers on the strain of longitudinal reinforcements,the strain of transverse reinforcements and the horizontal displacements of coupling beams are obvious,which with the increase of volume fractions of steel fibers,the ultimate strains of reinforcements and the ultimate displacements of coupling beams increased significantly. |
