蜂窝状钢骨混凝土L形截面异形柱的抗剪性能分析

SHEAR BEHAVIOR OF L-SECTION HONEYCOMB STEEL-REINFORCED CONCRETE COLUMN

为了探讨蜂窝状钢骨混凝土L形柱斜截面受力性能,利用有限元软件ANSYS,分析腹板肢偏移系数、轴压力系数、剪跨比、混凝土强度、配箍率、型钢强度、配钢率、腹板肢钢骨腹板开洞率、钢骨腹板高厚比等因素对蜂窝状钢骨混凝土L形柱斜截面受力性能的影响。结果表明:轴压力系数、剪跨比、混凝土强度、型钢强度、配钢率、腹板肢钢骨腹板开洞率、钢骨腹板高厚比等对蜂窝状钢骨混凝土L形柱的抗剪承载力影响较大;而腹板肢偏移系数、配箍率对柱子的抗剪承载力影响有限。

To investigate the bearing performance of oblique section of honeycomb steel -reinforced concrete L-shaped column, the software ANSYS was used for the analysis of the influential factors such as offset coefficient of web , axial compression ratio, shear span ratio, concrete strength, hooped reinforcement ratio , steel strength, steel ratio, opening holes ratio of steel web and height-thickness ratio of steel web on the bearing performance of oblique section of honeycomb steel-reinforced concrete L-shaped column .The results indicated that axial compression ratio , shear span ratio, concrete strength, steel strength, steel ratio, opening holes ratio of steel web and height-thickness ratio of steel web had great influence on the shear strength of the honeycomb steel reinforced concrete L -shaped column .But the offset coefficient of web and hooped reinforcement ratio had a limited effect on the shear capacity .
