摘要
运用大型通用有限元软件ANSYS,对沿跨度方向受竖向均布荷载的抛物线拱进行平面外稳定性分析,从含钢率、混凝土强度等级、钢材等级、面外长细比以及矢跨比参数等方面,分析了影响钢管混凝土抛物线拱平面外稳定性的主要因素,并通过数据整理拟合,得出了钢管混凝土抛物线纯压拱平面外的简便算法。
The element model of out-of-plane buckling of slender parabolic concrete-filled steel tubular arches with uniform compression was analyzed by ANSYS software. A parametric analysis was studied the influcense of out-of-plane buckling of slender parabolic concrete-filled steel tubular arches,such as the ratio of steet area to concrete area,concrete strength,steel strength,rise-to-span ratio and slenderness ratio. Then obtained by data fitting parabolic to get the simple algorithm of out-of-plane buckling of slender parabolic concrete-filled steel tubular arches with uniform compression.
