［摘要］以鋼筋混凝土門形框架結(jié)構(gòu)為研究對象，在橫梁與立柱的交界部位使用橡膠混凝土，通過模型試驗，測試了結(jié)構(gòu)承載力、跨中應變、立柱應變、跨中位移隨橡膠混凝土使用量的變化規(guī)律。研究結(jié)果表明，橫梁的跨中應變決定了框架結(jié)構(gòu)的承載力；橡膠混凝土在橫梁與立柱交界部位的使用對結(jié)構(gòu)的變形有較大的影響；橡膠混凝土的合理使用，可以不降低甚至小幅提高框架結(jié)構(gòu)的承載力；橡膠混凝土在鋼筋混凝土框架結(jié)構(gòu)中推廣應用是可行的。

Abstract:Taking reinforced concrete portal frame structure as the research subject, rubber concrete was used at the boundary part between the beam and the column. The model test was conducted to study the change law of the structural bearing capacity, midspan strain, column strain and midspan displacement with the usage of rubber concrete. The research results show that the midspan strain of the beam determines the bearing capacity of the frame structure; the use of the rubber concrete at the boundary part between the beam and the column has a great influence on the deformation of the structure; the reasonable use of the rubber concrete will not reduce the bearing capacity of the frame structure,some slightly improved; the application of rubber concrete in the reinforced concrete frame structure is feasible.
Keywords:rubber concrete; frame structure; bearing capacity
