实际工程中，由于荷载偏心等影响，使得钢梁常常同时承受弯矩和扭矩的联合作用。
Steel beams are often suffering combined bending and torsion as the influence of eccentric load in actual projects.
扭矩以推力与曲柄偏心距或旋转轴心至推力作用点的距离相乘计算。
Torque is calculated by multiplying the push by the crank offset, or the distance of the push from the rotating shaft.
最后介绍了预应力混凝土连续曲线箱梁桥的设计，重点讨论了总体设计，钢束预应力的损失的计算，预设支座偏心调整扭矩等设计中的关键问题。
Lastly design of P. C. continuous curved girder bridge is discussed in the paper, in especial prestress reinforcing steel bar's loss and bearing design.
