本文就一榀转换梁1/4缩尺模型在垂直荷载和水平荷载作用下的试验和有限元分析结果,对非满跨错位剪力墙框支转换梁的受力性能进行的研究表明,非满跨错位剪力墙不但降低了转换梁的剪跨比,改变了梁端约束状态和梁的受力状态,而且因错位剪力墙的受力特性与剪力墙错位,使梁处于拉、弯、剪、扭的复杂受力状态,从而导致梁在剪跨比较小区段出现剪切破坏。
In this paper, the results of tests and finite element analysis of a 1⁄4 scale model of a converted beam under vertical and horizontal loads are performed. The results of a study on the mechanical behavior of a converted beam of a non-full-span dissimilar shear wall frame beam show that The full-span misalignment shear wall not only reduces the shear-to-span ratio of the converted beam, but also changes the constraint state of the beam end and the force state of the beam, and the force characteristics of the misaligned shear wall and the misalignment of the shear wall cause the beam to pull, The complex stress states of bending, shearing, and twisting cause the beam to shear shear at a relatively small section of the shear.
