hinged girder meaning in Chinese

铰接梁

In allusion to section modality and transverse joint of common span bridges , we choose two kinds of calculating theories in transverse distributing calculate process : the theory of rigidity crossbeam and the theory of hinged girder and slab . making the use of the theory of optimized design , i constitute mathematics model and choose appropriate calculated method . and find the form and detail dimension of section when beams of the bridge satisfy bending moment ^ shearing force and torsional moment
在用横向分布理论计算单梁扭矩过程中，针对现有常用跨径桥梁的截面形式和横向连接状况，选取了两种计算理论：刚性横梁法和铰接梁(板)法，利用结构优化设计原理，建立主梁承载力的数学模型，选择合适的优化计算方法，得出在满足弯剪扭承载力要求时主梁的细部尺寸。
