The behavior of reinforced-concrete structural elements under moving loads involves many complex parameters related to material properties, vehicle loading, environmental changes and structural response. It is difficult to generate the real conditions of l ...
New methods are required for sustainable and economical management of bridges. Efficient management can be achieved by a detailed understanding of bridge behavior through monitoring and model-based data interpretation. This paper presents a methodology to ...
L'avion fait croître les émissions de CO2 imputables aux Suisses. La politique envisage une taxe sur les billets. Cet article documente l'évolution des émissions, examine les solutions envisagées et en propose une autre: l'attribution d'un budget à chaque ...
The strengthening of existing steel structures against high-cycle fatigue (HCF) loading has become one of the most important topics of interest in structural rehabilitation. Apart from the conventional strengthening techniques that incorporate bulky and he ...
The fatigue safety of the reinforced concrete (RC) deck slab of a sixty-year-old steel-concrete road viaduct is questioned based on the results of code-based "re-calculation". Since strengthening intervention would lead to major costs, detailed investigati ...
The fatigue safety of the reinforced concrete deck slab of a sixty-year-old steel-concrete road viaduct as well as the riveted steel girders of a 130 year old railway bridge was questioned based on the results of conventional assessment consisting in "re-c ...
Bonded fiber reinforced polymers (FRPs) reinforcement systems have traditionally been found to be an efficient method for improving the lifespan of fatigued metallic structures and have attracted much research attention. Nevertheless, the performance of a ...
At the end of the 1980’s, a series of existing bridges in Switzerland were equipped with a network of hydrostatic leveling devices, with the aim of following their longterm behavior. Some of the bridges were known to exhibit a steady increase in their defo ...
