The curve of interaction between ultimatemoment and ultimate torque .
极限扭矩与极限弯矩之间的相关关系。
2
This means that no matter how we think, the ultimatemoment is not fully predictable.
也就是说无论怎样思考，最终的一瞬都是无法完全预见的。

Calculating methods of cracking moment, ultimatemoment, stiffness of the beams strengthened by steel plate are offered according to the non-linear relationship between stress and strain of concrete.
