摘要
通过对 4个足尺试件在低周反复荷载作用下的对比性试验研究 ,分析了框架梁内纵筋和外贴钢板应变情况 ,并分阶段比较了粘钢板与钢筋混凝土的共同工作情况 ,初步给出了整体工作系数 φ值 ,建立了组合受弯承载力公式。
By comparing tests of low cyclic reversed loading on four full- size members,the strains of steel plate- sticking reinforced frame beam are analysed and co- working conditions of the steel plate- sticking and reinforced concrete are compared.The integral working coefficient φ is also given primarily and bending resistance equations are set up.
