Reconstruction of timber girder floor structure with composite timber-concrete structure

This paper analyzes the reconstruction of old timber girder floor structures. Since timber girders were in good condition a new relatively thin concrete slab has been placed on them, and the two materials have been coupled using sleeper screws. This paper also explores the application of lightweight aggregate concrete instead of normal-weight aggregate concrete for timber-concrete composite structure. Finite element method was used for modelling of composite structures using ABAQUS and COSMOSM software. The aim of this study was to determine the advantages of using timber-lightweight aggregate concrete composite structure, compared to solutions in which timber-conventional concrete composite structure or reinforced concrete slab are used.
