本文对钢筋砼高剪力墙中跨高比小于2.5的连系梁提出了一种新的抗震方案:用纵向水平缝把连系梁分为上、下两个相同构件,但它们在跨中却有砼键连系着。本文介绍了这种抗震连系梁试验的主要结果、承载力和截面抗弯刚度的汁算公式以及延性与耗能的性能,并提出了设计建议。
In this paper, a new anti-seismic scheme is proposed for connecting beams with a mid-span height ratio of less than 2.5 in reinforced concrete high shear walls. Vertical horizontal joints are used to divide connecting beams into upper and lower two identical components, but they are in the middle. There is a link between the keys. This paper introduces the main results of this kind of anti-seismic linkage beam test, the bearing capacity and the formula for the calculation of cross-section bending stiffness, as well as the properties of ductility and energy dissipation, and proposes design suggestions.
