蜂窝状钢骨混凝土L形截面异形柱的抗剪性能分析

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。

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

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.
