摘要
Abstract
An analysis was conducted on the overall stress-strain behavior of ultra long concrete structures under temperature stress,as well as the changes in the specific reinforcement of structural beams and columns.It was found that for the edge span of the structure,the maximum interlayer displacement was observed under temperature difference load,gradually decreasing upwards.At the same time,the main trend in the plane was that the stress on both sides was small,and the stress in the middle was large;The reinforcement of structural beams and columns mainly manifests as an increase in the top reinforcement of the frame beam in the Y-direction of the overlength direction of the lower floor,while the other changes are relatively small.The reinforcement of the frame columns remains unchanged.The increase in bottom reinforcement in the overlength Y-direction of the floor reinforcement is significant,with the roof and second floors being more prominent,with reinforcement values increasing by nearly 10％to 45％.关键词
