Notes:
This paper describes a dynamic test carried out on intact and damaged FRP compositebeams with fixed-fixed boundary condition. Hammer excitation is used to excite the beam at fixedlocations. The modal parameters are extracted from the time response using a time domain analysis,i.e. the stochastic subspace identification technique. In order to introduce damage, two sections ofthe beam are bonded together using an epoxy adhesive, and then a static test is carried out. For thestatic test, a 3-point bending -configuration is used, i.e. the beam is fixed at both ends and a staticload is gradually applied in the middle of the beam using a screw jack. Different static load steps,and in turn different damage stages, are considered. After each load step, dynamic measurementsare carried out. The results obtained from both tests are presented and analysed
