中文摘要:

实验研究了再生砖骨料混凝土梁斜截面的抗剪极限承载力、破坏形态和裂缝开展等情况,并与普通混凝土梁进行对比。分析再生砖骨料混凝土梁的抗剪机理,提出了适用于再生砖骨料混凝土梁的抗剪承载力公式。实验与分析结果表明:再生砖骨料混凝土梁和普通混凝土梁的破坏形态和裂缝开展情况相似,但再生砖骨料混凝土梁的抗剪极限承载力低于普通混凝土梁。采用提出的抗剪承载力公式计算再生砖骨料混凝土梁的抗剪极限承载力是可行的,有一定的安全储备。

英文摘要:

The paper studied the ultimate bearing capacity, the fracture morphology and the crack development situation of diagonal section of the recycled brick aggregate concrete beam, and contrasted the beam with common concrete one. By analyzing the shear mechanism of the recycled brick coarse aggregate concrete beams, this paper provided a formula related to the shear capacity of recycled brick aggregate concrete beams. The results show that the fracture morphology and crack development of the recycled brick coarse aggregate concrete beam is similar to common concrete beam, but the ultimate bearing capacity is less then that of the common concrete beam. The formula can be used to calculate the bearing capacity of the recycled brick coarse aggregate concrete beam and contains a certain security reserve.
