摘要
文章采用ABAQUS有限元软件中非线性弹簧单元SPRING2对钢筋与超高韧性水泥基复合材料粘结性能进行数值模拟,得到拉拔力与滑移量曲线以及钢筋应力和粘结力沿锚固长度方向分布情况。试验与模拟结果吻合较好,证明用SPRING2单元来模拟钢筋与UHTCC间的粘结滑移是可行的。
In this paper,the nonlinear spring element SPRING2 was adopted to simulate bond property between steel reinforcement and ultra high toughness cementitious composites（UHTCC） based on the finite element software ABAQUS.The load versus displacement relationships,reinforcement and bond stress distributions along the anchorage region are obtained.The agreement between calculated and measured results indicates that the SPRING2 element is feasible to simulate the bond-slip behavior between steel reinforcement and UHTCC.
