Bent waveguide is an indispensable unitofstructure used in PLC (Planar Lightwave Circuit).
弯曲波导是平面光波导器件中不可缺少的结构单元。

A new unitofstructure Multi-rib Wall is introduced. The hysteretic model and the damage model of Multi-rib Wall are given which based on experiment of 26 Multi-rib Walls.
By analysed on vibration theory we knew that the load js a static load in mechanics of materials, when the loaded time is 6-8 times as much than the natural vibration period of the unitofstructure.
