Besides , on the basis of the test data under bending and torsion and the theoretical analysis on the tubular , the relative relationship between the bearing values is derived . second , based on the elastic theory , this paper deduces the rules of stress distribution and main physical and geometric parameters by analyzing the elastic stress distributions when the tubular is under such conditions as torsion , bending , shearing , combined bending and torsion , and combined shearing and torsion ; additionally , taking the strength criteria of concrete and steel as reference , the paper proposes a set of theoretic equations for the relative relationship between the bearing values 本文利用弹性理论对扭转、弯曲、剪切、弯扭联合作用、剪扭联合系列作用下的构件弹性应力分布进行了研究,得出应力分布与主要物理和几何参数的规律;同时引入混凝土及钢的强度准则,得出了弯扭、剪扭复合应力作用下的承载力相关关系的理论方程,可供工程设计使用。
