1987年《建筑技术》第4期《钢筋混凝土梁箍筋的合理计算方法》一文,就承受均布荷载的简支梁作了分析计算,对于降低钢筋消耗会起积极作用。然而,工程中这种梁仍属少数,普遍的是大量受到更为复杂荷载作用的简支梁、连续梁和框架梁。下面就这类梁分段配箍及简便计算作一探讨。 1.梁可以根据剪力大小分段配箍从工程实践及有关资料看,分段配箍的梁很少,大量的是一跨梁按最大剪力值通长配置等量箍筋。这一现象不能说都合理。
In the article “Reasonable Calculation Method for Reinforced Concrete Beam Stirrups” in the 4th edition of “Architecture Technology”, 1987, the analysis and calculation of the simply supported beam subjected to uniformly distributed loads is performed, which will play a positive role in reducing the consumption of reinforcing bars. However, this kind of beam is still in the minority in the project, and a large number of simple-supported beams, continuous beams and frame beams that are subjected to more complex loads are common. The following section discusses the distribution of hoop and the simple calculation of such beams. 1. The beam can be divided according to the size of the shear force. According to the engineering practice and related data, there are few beams with segmented hoops, and a large number of beams are configured with the same amount of stirrups according to the maximum shear force. This phenomenon cannot be said to be reasonable.
