| 摘 要： | 土木建筑工程中有许多双向受弯构件,如承受风荷载的墙梁、框架的边梁等.目前对于双向受弯构件斜截面抗剪强度的研究尚涉及不多.本文对12根在集中荷载作用下的矩形截面无腹筋双向受弯约束梁进行了斜截面抗剪试验研究,探讨了其抗剪机理和抗剪性能.着重分析了四个影响抗剪强度的主要因素：荷载斜弯角、剪跨比、弯矩比、纵筋配筋率,提出了适用于矩形截面无腹筋双向受弯约束梁抗剪强度的计算方法.

| Abstract: | As is known to all,there are many biaxial flexural members on the civil engineering.For example,the wall-beam supporting wind loads,the border-beam of form.Now there is little on the research of the shear strength of concrete rectangular beams under biaxial bending.In this paper,twelve restrained concrete rectangular beams without web reinforcement subjected to biaxial concentrated loads were tested so as to explore their shear mechanism and their behavior.Four main factors affecting the shear strength were analyzed:load inclination,the shear span-ratio,the ratio of maximum negative moment to the maximum positive moment,longitudinal reinforcement ratio.The formula for calculating the shear strength of restrained concrete rectangular beams without web reinforcement under biaxial bending is presented in this paper. |
