| 摘 要： | 运用有限元理论和增量迭代方法对预应力连续钢梁在弹性及弹塑性阶段的受力性能进行了分析，探讨了施加预加应力以及由此产生的次弯矩对连续梁的内力分布，刚度以及变形的影响，并编制了相应的计算程序，通过对两根预应力双迭连续梁的试验研究，验证了理论分析的可靠性。

| Abstract: | Appling the finite element theory and incremental iterative method,the behavior of aprestressed-steel continuous beam in elastic and elastic-plastic range is analyzed,The effects ofprestressing and secondary moment due to prestressing upon the distribution and change of the momentand stiffness of the member are studied .On this basis a computer program is developed .Thereliability of the theoretical analysis is verified by the experiment research of 2 two-prestressed steel beams. |
