摘要: 分析了均布交变载荷作用下两跨连续梁的自动适应 ,求解了自动适应极限载荷 ,它是弹性极限载荷的146倍 ,文中分析对多跨连续梁建立自动适应算法有参考价值

关键词: 自动适应, 残余弯矩, 连续梁

Abstract: The shakedown of the continuous beam with unifromly distributed load subject to alternating is analyzed in detail and maximum loads of the shakedown have been determined.It is 0 46 times more than elastic maximum load.It makes a point that the analysis is applicable to continuous beam with many supports.

Key words: shakedown, residual moment, continuous beam
