How To Assess The Load-bearing Capacity Of The Construction Of Bailey Steel Bridge?

It is necessary to know the strength index of the bridge structure, including flexural strength, shear strength and compressive strength, to evaluate the load-bearing capacity of the construction of Berei steel bridge. These indicators are usually obtained by calculation or experiment. For the special structure of bailey steel bridge, it is also necessary to consider its special shape and connection modeviley steel Bridges are usually made of steel and truss structure is their main feature, so it is necessary to assess the strength of their various key parts.

Secondly, it is necessary to consider the design load to evaluate the bearing capacity of the construction of bailey steel bridge. The construction of bailey steel bridge usually needs to bear a variety of loads such as self-weight, driving load, wind load and so on. Among them, the dead weight is the gravity of the bridge itself, the driving load is the load imposed by the vehicles running on the road bridge, and the wind load is the wind force caused by the cross section and shape of the bridge. When assessing the load-bearing capacity of Bridges, it is necessary to determine the characteristic value of each load according to the design code and carry out the corresponding calculation.

Structural analysis is also needed to assess the load-bearing capacity of the constructed bailey steel bridge. Through structural analysis, we can get the internal force and deformation of each key part of the bridge, as well as the stress state of each member. For the special structure of bailey steel bridge, the common analysis methods include finite element analysis and elastic theory analysis. Through structural analysis, we can evaluate the stress of each key component of the bridge and the bearing capacity of the whole bridge structure.
