The HD200 bailey bridge is similar to the HD100 bailey bridge and 321-Type panel bridge from their appearance. The difference is its increased panel height to 2.134m. For some bridge with longer spans, lt 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. Sway Brace is made of integral type and connected with the transom to improve the overall stability of the assembled steel bridge. 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,HL-93 and pedrail-50 etc.

ALLOWABLE STRESS OF PANEL
Material yield strength of panel σS=345MPa
Material allowable stress [σ]=0.8×σS=276 MPa
Allowable bearing stress [N]= [σ]×F×φ=276×2548×0.751=528kN=54t
Stability factor of chord SSφSS=0.751;DS φDS=0.897
Allowable moment of panel [M]= [N]×h=528×2.134=1127kN·m=115t·m
