(2012-06)A common method of collecting traffic loading data across a large road network is to use a network of permanent pavement-based WIM systems. An alternative is to use one or more portable Bridge Weigh-In-Motion systems which ...

(2010-09-02)Increasingly buildings and their occupants are negatively impacted by traffic–induced vibrations. The continuous application of vibrations is particularly detrimental for historic masonry buildings and for very modern ...

(2012-12)When collecting truck loading data on a primary road network a common, approach is to install a large network of permanent pavement based Weigh-In-Motion systems. An alternative to this approach would be to use one or more ...

(Faculty of Engineering, University of Porto, 2012-07-22)Bridge structures are subject to continuous degradation due to the environment, ageing and excess loading. Monitoring of bridges is a key part of any maintenance strategy as it can give early warning if a bridge is becoming ...

(2012-10)The axle forces applied by a vehicle through its wheels are a critical part of the interaction between vehicles, pavements and bridges. Therefore, the minimisation of these forces is important in order to promote long ...
-
(2012-09)In the past decade there has been a considerable increase in the number of bridges being instrumented for the purposes of vibration based monitoring, typically to monitor dynamic parameters such as frequencies and mode ...

(2012-09)The structural response of a material to a load that is applied rapidly (dynamically) or applied very slowly (statically) can be considerably different. A vehicle moving across a concrete bridge represents an example of a ...
-
(Taylor and Francis, 2012-07)Empirical mode decomposition (EMD) is used to detect and locate damage in a bridge using its acceleration response to the crossing of a vehicle. EMD is a technique that converts the measured signal into a number of basic ...

(2013-07-10)The translational restraints associated to pin and rocker bearings are typically idealized in the form of fixed and free conditions. However, elastomeric bearings need to be represented with springs to reasonably predict ...

(2015-05-14)Modal analysis characterizes the dynamic behaviour of structures, by means of their natural frequencies and mode shapes. Since these parameters are related to the flexural stiffness, many damage detection methods are based ...
