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 employed the method of alternating joints between Reinforcement
Chords 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 braced frame and panels is fixed through bridging
so as to prevent the whole bridge from side bending. After the
erection, there will be a pre-arched degree over the span of the
bridge. Besides it can be assembled into single-lane bridges. The compact 200 panel bridge can also be assembled into double lane bridge, hence it broadens
its application range. It is suitable for the load designs of
HS-15, HS-20, HS-25 and pedrail-50 etc.
