摘要
在圆形截面构件承受的轴力很小而承受的弯矩很大的情况,混凝土的受压区为弓形,偶尔还可能出现混凝土的受压区为三角形的情况。虽然上述情况不如矩形受压区常见,但上述问题的解决却有工程实际意义。提出了上述两种情况下的正截面受弯承载力的设计方法,通过试算可以看出,两种情况下的运算均较简便,通过简单的手算即能使问题得到解决。
Sometimes the circle-section element bears bigger moment with less axial force in a project. In this condition, the compressive region of the concrete will be arched, occasionally will be triangular for sometime. Although the above two situations are not so common as the situation of rectangular pressed, the solutions are still have certainly realistic meaning to the project. This article describes the design method of the positive section bent bearing capacity under the above two situations. According to the test, the operation under the two situations is quite simple and convenient. Problems can be solved by simple calculation with hand.
