【摘要】 蜂窝状钢骨混凝土T形柱,是一种很适合于当今钢结构住宅建筑的新型异形柱。为了比较全面地探讨该新型构件的斜截面抗剪能力与变形特性,本文利用ANSYS有限元分析软件对T形截面柱进行非线性有限元分析,研究轴压力系数、剪跨比、配钢率、配箍率、混凝土强度等主要参数变化对该新型构件斜截面抗剪性能的影响及其规律,并提出相应的设计建议。研究表明,该新型柱的斜截面极限抗剪承载力随轴压系数、配钢率、配箍率、混凝土强度的增加而增加,但随剪跨比的增加而降低;其中剪跨比和轴压系数是影响T形柱斜截面抗剪性能的比较敏感的因素。更多还原

【Abstract】 The honeycomb steel reinforced concrete(SRC) T-shaped column is a new special-shaped column,which is very suitable for today’s steel structure resident house.The paper carried on the non-linear finite element analysis on the honeycomb SRC T-shaped column with multi-parameter by the ANSYS procedure to inspect the influence of main factors,such as axial pressure ratio,shear span ratio,the steel ratio,the reinforcement ratio,the concrete strength and so on,on the oblique section shear capacity and their laws.Based on these,some suggestions for design were given.As the study shown,along with the increasing of the axial pressure ratio,the steel ratio,the reinforcement ratio and the concrete strength,the ultimate shear capacity of the new column increases,but it will drop with the increasing of the shear span ratio;the axial pressure ratio and the shear span ratio are extremely sensitive to the oblique section shear performance of T-shaped column.更多还原
