Dynamic experiments were conducted on an all-FRP composite pedestrian bridge. The structure was excited by impact and human-induced vibrations. The peak-picking method and stochastic subspace identification method were used to extract structural dynamic ch ...
Reinforced concrete bridge deck slabs without shear reinforcement can be subjected to concentrated or distributed loads of important magnitude. Under these loads their structural response is not always ductile. In particular under concentrated loads their ...
So-called “non-load bearing” parts of (railway) bridges increase the stiffness and decrease the stresses in short span bridge structures. The rail track, consisting of ballast, sleepers and rails, has a non-linear behaviour and its rigidity depends on the ...
Herein, a probabilistic model for predicting the effect of post-weld treatment on the fatigue performance of the welded joints in tubular truss bridges is described. Specifically, a probabilistic LEFM-based model is first developed for the fatigue analysis ...
Bridges suspended by prestressed steel tubes. The structural system of suspended girders was used for bridge structures as early as the beginning of the 19th century. Because of the technological advancements in the field of prestressing and due to the hig ...
It has been known for more than 150 years that action effects in bridges due to traffic action are higher than it has to be expected for purely static loads. In the design of road bridges, this difference is considered by multiplying static traffic loads w ...
This paper reports on the composite action developed between pultruded FRP bridge deck systems and the supporting main girders for road bridges. Presented are requirements that an FRP deck must satisfy in order to function as part of the upper chord of the ...
The presence of post-tensioning tendons in webs decreases the load-carrying capacity of the compression struts that are necessary to transfer shear forces. This effect has been known for a long time, but was initially not included in design codes. In parti ...
Due to their aesthetic and structural advantages, tubular space truss structures are enjoying increasing popularity in modern bridge construction. The use of cast steel nodes for the joints between the circular hollow section members is also becoming incre ...
Up until today reinforced concrete has been used in most cases for the manufacturing of bridge decks. Depending on the quality of the work carried out, defects can already occur after only a few years. These defects mostly appear in the form of corrosion o ...
