Over the past few years steel structures are becoming a common feature in all manufacturing industrial buildings. Steel structures is particularly suitable for all buildings or industrial sheds. In some of manufacturing industries for conversion of raw material to usable material some machine operations are required in that processes, increases in the temperature will affect the steel frame structure. In order to study the performance of steel structures, different models were developed in STAAD Pro software by varying the types of bracings in structures. In which the horizontal beams connecting vertical elements are assumed as pinned connecting medium having equivalent distributed stiffness properties. Here the structure is analyzed for wind load and static analysis for different models by varying the temperature and the output of the models are evaluated to have a comparative study of their performance for thermal stresses. From the analysis results by compared to structures with other bracing configuration it is found that due to variation in temperature thermal stresses is less in Single diagonal bracing structure. Hence Single diagonal bracing structure are good type of bracing in resistivity of the structure.
