| 摘 要： | 为比较准确地确定钢筋混凝土连续梁纵向各点的挠曲变形 ,在总结工程实践中计算梁跨中挠度方法的基础上 ,提出计算连续梁纵向挠曲线的共轭梁法 ,此方法考虑了连续梁刚度沿梁长变化及相邻跨荷载对挠曲线的影响。与单位力法相比 ,基于计算机的共轭梁法一次就能够求得连续梁的挠曲变形分布曲线 ,并能迅速得到其最大挠度

| Abstract: | In order to ascertain the bending deflection of reinforced concrete continuous beams accurately, a conjugate-beam method to calculate the longitudinal deflection curve is presented based on the analysis of the calculation methods for midspan defection of beams in practice. The influence of the beam stiffness varying along the beam and the load of adjacent spans is considered. In contrast to the unit load method,the longitudinal deflection curve of the whole continuous beam can be derived at a time and the maximal defection obtained rapidly by using the presented method with the aid of the computer. |
