摘要: 介绍一个装配整体式钢筋混凝土框架中柱节点与另一个现浇钢筋混凝土框架中柱节点的对比试验。试验结果表明,梁柱间采用齿槽接头,梁的主筋采用滚轧直螺纹接头的装配整体式梁柱节点的受力性能是可靠的;试验还表明,节点处楼板内的钢筋对梁负弯矩承载力的贡献是很大的,不容忽视,否则就不能满足强柱弱梁的要求。

Abstract: The contrast tests of one precast monolithic R. C. frame in terior column joint and one cast-in-situ R. C. frame interior column joint are presented. The test results indicate that it is reliable that the rolled parallel thread splicing of rebar is adopted in the rebar of beam in alveolus connection; and that the effect of rebar in the slab on bending moment capacity of the beam negative moment is remarkable and can't be neglected, or the principle of strong column, weak beam can not be satisfied.
