Abstract:
A three-segment simplified model was presented for describing the lateral displacement of steel staggered-truss framing system subjected to high temperature according to the structural attributes. Both the structural lateral displacements and the additional overturning moment induced by high temperature were analyzed, and the corresponding calculation methods were proposed. Furthermore, associated with the finite element method, a case was given for clarifying the above method. Results show that the proposed simplified model can describe the lateral deformation of steel staggered-truss structure under lateral force and high temperature well. The calculation methods for the lateral displacement of structure and the additional overturning moment are relative simple, feasible, and have considerable precision.
