摘要
导出了求解钢筋混凝土梁变形的单元刚度矩阵；用有限元法求梁的挠度时，考虑了混凝土的徐变与收缩的影响．将梁１半跨取为１个单元、梁２半跨取为１个、２个、３个单元求解出的梁跨中挠度值与试验结果非常接近．
This paper describes a finite element method for the deflection of reinforced concrete beam due to loads,creep and shrinkage.The element stiffness matrix is derived.The test dada of two beams are compared with those computed by means of this method.
