Abstract: The aim of the research in the present article is to access the working of Girder Pin connection when placed between bottom of fully loaded Girder and top of column in Boiler Supporting Structure. The analysis is done using ANSYS analytical software. The deflections and end reactions of various girder sizes with appropriate span length used in boiler structure are considered and the results are obtained. The end reactions obtained are further applied on girder pin. Current paper presents the contact stresses and deflection developed at the Girder pin due to the compressive loads from Girder. Further using stress values obtained it is compared with maximum allowable stress of plate and thereby selecting appropriate plate and rod thickness i. e optimising the components used in Girder pin connection.
