摘要
本文通过两个对比组共六个试件的试验研究指出,配置在孔间纵肋内的箍筋对横孔板受剪承载力影响甚微,可以忽略不计；沿垂直于孔道间纵肋的方向设置横肋则可以显著提高横孔板的受剪承载能力,从而减小圆筒芯空心楼盖在两个方向抗剪能力的差距,使现浇空心楼盖的设计更趋合理。
Through the study on two contrast groups and six specimen, this article indicated that stirrups placed in the longitudinal ribs between the ducts would cause little effect on the carrying capacity of cross bore slabs, which could be negligible. Installing lateral ribs perpendicularly to the longitudinal ribs between the ducts may improve the carrying capacity of cross bore slabs markedly, so as to reduce the difference of the circular hollow floor at two directions for more reasonable design.
