摘要
本文利用随时间调整的有效模量法，结合有限元步进法，编制了钢—混凝土结合梁时效分析程序，以一座三跨连续钢—混凝土结合梁桥为例，分析了成桥到成桥后10年其截面应力和变形的变化情况。
Described in this article is a program for time - dependent analysis of steel - concrete composite beams developed using the age - adjusted effective modulus and the step - by - step finite element method. A three - span conctinuous steel - concrete composite beam bridge is analized of the variation of the sectional stress and deformation on completion of the bridge and ten years later.
