通过文献资料[1…3]的研究证明:纵向压力对构件斜截面的强度有很大影响。当纵向压力作用于截面形心时,它对横向受力构件的强度起保护作用;当纵向压力偏离截面的形心时,它影响构件斜截面的强度,显然,斜截面的强度不仅与纵向压力,而且还与相应偏心距的正负方向和数值大小有关。为了揭示各种因素对构件斜截面强度的影响程度,对矩形截面钢筋混凝土梁式构件进行实验,该梁
The study of literature [1...3] shows that longitudinal pressure has a great influence on the strength of the oblique section of the member. When longitudinal pressure acts on the cross section centroid, it protects the strength of the transverse force member; when the longitudinal pressure deviates from the centroid of the cross section, it affects the strength of the oblique section of the member. Obviously, the strength of the oblique section is not only the vertical pressure but also the longitudinal pressure. , but also related to the positive and negative direction and magnitude of the corresponding eccentricity. In order to reveal the degree of influence of various factors on the strength of the oblique section of the member, an experiment was conducted on a rectangular section reinforced concrete beam member.
