Abstract


Beam string structure is developed in recent years and the rise of a new kind of spatial structure . Most domestic Beam String Structure Research in force structure performance and stability such as its fire resistant performance aspects almost is blank , with the beam string structure in large span space structure increasingly widely , its in fire case of structural properties of the growing number of structural engineers important , it is necessary to conduct in-depth analysis . Application of large span chord truss engineering Chaozhou Stadium as an example , ANSYS finite element analysis software to establish the Zhang chord beam of finite element model , by changing the material parameters and applying a temperature load of to consider the temperature on the structure , and consider the geometric the nonlinear material nonlinearity to simulate the response characteristics of the structure under different temperature , and pointed out the weak parts of the fire resistance of the structure , simulation truss string structure fires destroy the whole process . This article discusses the impact of beam string structure parameters change its fire resistance , and provide a reference for fire resistant design of beam string structure .
