Abstract: An analytical model for load-displacement curves of concrete beams is presented. The load-displacement curve is obtained by combining two simple models. The fracture is modeled by a fictitious crack in an elastic layer ...

Abstract: In this note, modal parameter and wave load identification by calibration of ARMA models are considered for a simple offshore structure. The theory of identification by ARMA calibration is introduced as an identification ...

Abstract: This article deals with the dynamic behavior of a reinforced and posttensioned concrete structure for applications in wind turbine towers. Measurements were performed using triaxial accelerometers in a 30 m high tower ...
