ON FINITE ELEMENT MODELLING AND MODEL UPDATING OF MULTI-STOREY TIMBER BUILDINGS

Abstract

The results of three case studies of timber and hybrid timber buildings have been reviewed. For each case study, experimentally obtained modal data was available. A detailed numerical finite element (FE) model of each building has been developed and used to carry out sensitivity analysis on the uncertain FE modelling parameters and model updating of the most influential input parameters. The importance of several modelling parameters and assumptions is discussed: perpendicular to the grain deformations of floor slabs, connections between cross-laminated timber panels, floor slab deformability, vertical foundation stiffness, and stiffness effect of the façade.
