Application of the compact standard 200 panel bridge:
Single lane: Bridge deck width: 4.2m.
Span length:
9.14-60.9m
Double lanes: Bridge deck width: 7.35m.
Span length: 9.14-57.9m
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.
