Service Load Analysis of Timber Construction Truss

Abstract

This study aims to determine the service load capacity of existing truss construction using the wood material. Analysis and calculations were performed on tensile members, compression members,connection, and deflections that occur using the standard SNI 7973 : 2013. The existing truss construction needs to be analyzed for its overall strength so that the function of the building can be maximized. The results of the research on the existing truss construction obtained that the value of the truss construction capacity in carrying the service load was due to the strength of the connection with a service load of 350 kgf/m. The deflection that occurs is 35.5 mm, far beyond the maximum deflection of 7.14 mm, so it is necessary to repair the connection by increasing the number of connecting devices or replacing the connection tools using bolts.
