Structural Safety Study of an Existing Wooden Roof Structure

During the use of the wooden roof structure, different degrees of damage are caused by corrosion, substructure damage, uneven foundation settlement and other diseases, so the structural safety appraisal of the existing wooden roof structure has become one of the main problems to be solved. By taking the safety of the wooden roof frame of a silver company club in Silver City, Gansu Province as the research object, the structural safety research of the roof frame structure is carried out by the method of combining theoretical calculations and finite element calculation technology, and it is found that the theoretical calculation values of pine beams, tie bars, vertical rods and profiles near the supports are slightly larger than the finite element calculation results; the theoretical calculation results of pine beams, tie bars, vertical rods and profiles far away from supports are slightly smaller than the finite element calculation results; and the theoretical calculation results of pine beams, tie bars, vertical rods and profiles far away from supports are slightly smaller than the finite element calculation results. The theoretical calculation results of pine beams, tie bars, vertical bars and steel sections away from the support are slightly smaller than the finite element calculation results; the strength of some bars exceeds the permissible value, and the results of the study can be used as a reference for similar projects.
