摘要
研究与钢筋混凝土承载能力相关的滞回特性、刚度退化特性、强度衰减特性、耗能能力。结果发现剪跨比、轴压比、体积配箍率三个指标对承载力有很大影响;在反复荷载作用下,钢筋混凝土主要表现为剪切斜压破坏、弯曲破坏这两种破坏形态;轴压比可大大提高钢筋混凝土在地震作用下的耗能要求和延性。
Based on the seismic performance of reinforced concrete column test, in-depth study the hysteresis characteristics associated with reinforced concrete bearing capacity, stiffness degradation, strength attenuation characteristics and energy dissipation capacity. From the results of the study found that shear span ratio, axial compression ratio, stirrup ratio volume has a great influence on the bearing capacity of the three index. Under repeated load, the reinforced concrete main performance for bending shear baroclinic destruction, destruction of the two failure pattern. Axial compression ratio, it may improve the energy requirements of reinforced concrete under the action of earthquake and ductility. Finally, recommended shear baroclinic destruction, respectively in bending the corresponding formula for calculating the ultimate bearing capacity.
