The compact 200 panel bridge: The compact 200 panel bridge is similar to the compact 100 panel bridge from their

appearance. The difference is its increased panel height to 2.134m. It adopted the method of alternating joints

between Chords Reinforcement and the joints between panels. This method can decrease inelastic deformation

caused by the oversized pinholes. Pre-arch method is used to additionally cut down mid-span and vertical deflection to

a larger degree. Bolt-connected components use the orienting sleeve- fixing method to increase accuracy of

connections. Shear is created in orienting sleeves and tension is developed in bolts, which increase the usage life of

the bolts and ensure the safety of panel bridges. Wind resistant brace is made to be composite type and is connected

to transom/girders to improve overall stability of panel bridges. 
       

The part between supporting frame and panels is fixed through bridging in order to prevent the whole bridge from side

bending. After the erection, there will be a pre-arched degree over the span of the bridge. The compact 200 panel

bridge can be assembled into both single and double lane bridge, so it broadens its application range. It is suitable for

the load designs of HS-15, HS-20, HS-25 and pedrail-50 etc.

It's consists of bailey panel (normal ,high shearing force), transom (single lane, double lane), chord reinforcement, 1050 mm steel deck and other components.
