Abstract

Reconstructing impact forces can improve considerably structural health monitoring as the extent of damage can be better made out. In this work an inverse problem formulation to identify the pressure generated by a non punctual impact is investigated. Considering the case of linear elastic layered composite structures, reconstruction of impact pressure is performed through a finite element model of the structure and impulse response functions between the impact zone and sensors placed at known positions. Assuming that the pressure is uniform, reconstruction is carried out by regularized deconvolution based on generalized singular value decomposition. The infl uence of mesh size, modal truncation and time sampling on the reconstructed pressure is discussed.

The paper presents procedures of the slip calculation in steel and concrete composite structures under quasi-long-term load with flexible stud connectors. To describe the slip relation s = s (P), exponential functions are used as appropriate for using in engineering practice. The former already existing expressions for calculating the slip for short-term loads were generalized. The values of factors for the formula were determined on the basis of the experimental investigation.

Abstract

Nowadays, due to savings requirements, the heights of floor systems in multi-story buildings are reduced. To ensure passage of installation within a floor depth, a solution considering web openings is usually adopted in steel-concrete composite structures. Owing to the presence of web openings, the structural performance of a bearing member is affected not only in the final stage but also during the construction. Hence, the main purpose of this research is to evaluate the impact of web openings on the lateral-torsional buckling resistance of the steel part of composite girder in the erection stage. Comparison of lateral-torsional resistance of the steel girders with web openings derived by the analytical approach with results obtained by numerical model is presented and discussed.

Nowadays the most modern and economical bridges are designed as composite structures with orthotropic plates. In a traditionally designed composite bridge the trapezoidal, longitudinal stiffener is attached, welded to the cross girder web and to the bottom flange of the main girder. However in recent composite bridges with orthotropic plates designed by the UVATERV Co. the cross girder web and the trapezoidal, longitudinal stiffeners are not connected. This is a very important improvement, since in this way the amount of cutting and welding work can be reduced, however more importantly there is no need to consider the fatigue of the welds between the longitudinal stiffener and the cross girder web. On the other hand the disadvantage of this design that the plate-buckling phenomenon of the free edge must be taken into account. This paper studies the new orthotropic plate by the experimental tests.
