- 影响预应力预制梁(板)上拱值的因素分析
摘要:预制梁(板)预应力筋张拉后发生向上的上拱变形,上拱值直接反映了张拉力效应,是预应力张拉施工中的一个重要的力学指标。本文针对目前高速公路建设中梁(板)实际上拱值比理论上拱值偏低的现象,对影响梁(板)上拱值的多种因素进行分析和讨论。
关键词:预应力构件;预制梁板;上拱值;先简支后连续桥梁。
Analysis on Factors Effecting Upward Deflection Values of
Prestressed Precast Beams(Slabs)
Liu Dekun
Abstract: The upward deflection occurs after the prestressed reinforcing bars of precast
beams (or slabs) are tensioned, the value of which represents the effect of tensions
directly and is an important mechanical index in the ....
