(一) 钢筋混凝土整体楼盖交叉梁系的精确分析是一个比较复杂的问题,在实际工程中常采用简化计算方法,如在肋形楼盖中将主梁作为次梁的不动铰支承。实际上主次梁是整浇在一起的,支座并非是一个铰,主梁对次梁有弹性约束作用;其次,主梁总会产生一定的变形,因此也不是一个不动铰,而是弹性支承。在楼盖设计中怎样使其支座接近不 (1) The accurate analysis of the cross-beam system of the reinforced concrete integral floor is a more complicated issue. In practical engineering, simplified calculation methods are often adopted, such as the use of the main beam as the fixed hinge support of the secondary beam in the ribbed floor. In fact, the primary and secondary beams are cast together, the bearing is not a hinge, the primary beam has elastic restraint effect on the secondary beam, and secondly, the primary beam will always produce a certain deformation, so it is not a non-moving hinge, but Elastic support.
