摘要

为了研究活性粉末混凝土(RPC)层对混合深梁结构性能的影响，设计了12根钢筋混凝土简支深梁，并对其进行了两点荷载试验。结果表明，加RPC层的混合深梁增加了初始开裂荷载和极限荷载。受拉区RPC混合梁的极限荷载大于受压区RPC混合深梁的极限荷载。随着剪跨/总深度(a/h)比的减小，梁的首次开裂和极限荷载增大。载荷-挠度曲线随着a/h比的减小而变硬。

Effect of the location of reactive powder concrete layer on the behaviour of hybrid deep beams

In order to investigate the location effect of reactive powder concrete (RPC) layer on the structural behaviour of the hybrid deep beam, 12 reinforced concrete, simply supported deep beams were designed and tested under two-point loading. The beams were divided into three groups A, B and C. The results showed that the hybrid deep beams with RPC layer increases initial cracking and ultimate loads. The ultimate load in hybrid beams with RPC in the tension region was greater than the ultimate load in hybrid deep beams with RPC in the compression region. The first cracking and ultimate loads in the beams has increased with the decrease in shear span/overall depth (a/h) ratio. Load-deflection curve become stiffer as the a/h ratio has decreased.
