连续梁内力计算问题是工程设计中经常遇到的一个问题。特别是以钢筋混凝土为建筑材料的连续梁,在水利工程中被广泛采用。由于连续梁是超静定问题,计算较费时,所以,为了节省时间。提高效率,下文将简述“三弯矩方程”原理,并编制程序,以供读者参考。现有—N+1跨刚性支座上的连续梁,如图a Continuous beam internal force calculation is one of the most frequently encountered problems in engineering design. In particular, continuous beams made of reinforced concrete as building materials are widely used in water conservancy projects. Since continuous beams are statically indeterminate, calculations are time-consuming, so in order to save time. Improve efficiency, the following will be briefed on the “three-moment equation” principle, and the preparation of procedures for readers reference. Existing continuous beam N +1 cross-rigid support, shown in Figure a
