Examination engineering (short: "Examineering") of existing bridges comprises accurate determination of structural behavior and targeted use of advanced materials for improvement of structural behavior with the ultimate goal of limiting construction interv ...
A methodology inherent to existing structures is presented for the fatigue safety verification of riveted bridges. The suggested approach allows for the determination of updated action effects explicitly considering data from long term monitoring. Data fro ...
Ferroelectrics are usually defined as polar materials that display polarisation hysteresis. This is a functional definition. A structural definition exists too, based solely on symmetry arguments. The structural definition, useful e.g. for design of new ma ...
Road traffic loading is a highly variable process with a wide range of complex variables to consider. Consequently, various simplifying assumptions are required to efficiently model heavy traffic events for bridge safety verification, which reduce the accu ...
Experience has shown that when the models and methods that have been developed for the design of new structures are âblindlyâ used for the examination of existing ones, the management of civil infrastructure lacks substantially in financial efficiency ...
Tensegrity structures are spatial, reticulate and lightweight systems composed of struts and cables. Stability is provided by a self-stress state between tensioned and compressed elements. Tensegrities have received interest among scientists and engineers ...
This paper explores the system of laminated annealed glass beams post-tensioned through stainless steel tendons bonded to the lower glass edge. The tendons are first pre-tensioned and then adhesively bonded to the glass. The compressive pre-stress applied ...
With the occurrence of higher and more frequent axle loads on roads, in particular bridge deck slabs are more severely solicitated by fatigue loading. To avoid heavy interventions for strengthening of bridge deck slabs, an improved building material is use ...
Long term monitoring of structural elements of a 115 years old riveted railway bridge structure of high value as cultural heritage has been conducted. Monitored values were exploited by Rainflow analysis and served as the basis for the fatigue safety verif ...
Many stone masonry structures that were constructed in the past centuries are now counted towards the cultural heritage. The low strength and brittle behavior make these heterogeneous structures very vulnerable to various natural or man-made disasters such ...
