摘要
本文用试验及有限元计算方法,获得了钢筋混凝土构件与被粘钢板接触面上的粘接应力分布规律。以此规律为基础,拟合成了用数学方程表达的粘接应力分布形态公式。应用弹性力学的基本方程,推导出了粘接应力波及的范围与钢板中应力的关系。建立了混凝土构件拔拉受力锚固长度的计算公式和弯曲受力锚固长度的判别公式。
In this paper, the distributing law of the adhesive stress on the contacting surface between the concrete structural members and the adhesive steel plates is obtained by using the methods of experiment and the finite element analysis. Based on this law, a distributing shape formula of the adhesive stress expressed by using a mathematical equation is also obtained. Using the equation of the elastic mechanics, the rala-tion between adhesive stress range and the stress in steel plate is derived. The computational formula of the anchor length of concrete structural members under the tensile force and the judging formula of the anchar length under the bent state are set up.
