在弯矩和剪力的作用区段内,有效的薄壁截面受弯构件的斜裂缝开展和抗裂性的研究,乃是钢筋混凝土结构计算理论发展中最迫切的课题之一。在预应力薄腹梁斜截面上的裂缝形成过程有其自己的特点。例如斜裂缝的出现及其沿截面高度的开展,通常较与构件轴线垂直
In the role of bending moment and shear force, the effective thin-walled cross-section of the bent member to develop oblique cracks and crack resistance is one of the most pressing issues in the development of computational theory of reinforced concrete structures. The crack formation process on the oblique section of the prestressed thin web has its own characteristics. For example, the occurrence of oblique cracks and their development along the height of the section are usually perpendicular to the axis of the member.
