摘要
通过3榀框架的模型试验与40榀框架的全过程分析,讨论了装配整体式框架塑性内力重分布的特点,提出了在竖向荷载作用下,由预应力迭合梁构成的装配整体式框架节点弯矩最大调幅值;指出允许调幅值大小与施工阶段荷载有关,并小于同类型现浇框架的节点允许调幅值。
Through the test of three frame models and the full range analysis of forty frames, the peculiar properties of the stress redistribution in plastic stage in composite prestressed concrete frame has been discussed and the maximum allowable adjusting extent of moment in joint of such frame under vertical loading is suggested. It has been found that the allowable adjusting extent has a close connection with the magnitude of the loading applied during the constructional stage and that the maximum adjustable momentof composite frame is less than that of monolithic frame.
