In the design of tubular truss bridges, engineers have found the fatigue performance of the joints to be a critical aspect. In looking for ways to improve this performance, the use of residual stress-based post-weld treatments has been suggested. Although ...
The cities of Porto and Gaia have grown exponentially towards the seaside, but mainly to the inland. The river Douro, being the sheer existence of the two cities, has been left to an absolute state of lethe. The Douro River has become an amorphous element, ...
Dynamic energy due to ultimate limit state relevant traffic scenarios may completely be dissipated by plastic deformations without failure of the bridge element. If the structure shows significant strain hardening behaviour, the maximum static effect is al ...
This article examines the extent to which post-weld treatment by needle peening can improve the fatigue performance of tubular truss bridges. To do this, the various potential crack sites on several variants of a typical bridge are analyzed using a probabi ...
Direct load transmission experiments on hybrid short-span beam specimens for a novel bridge deck were performed. The sandwich construction consists of three layers: a fiber- reinforced polymer composite (FRP) sheet with T-upstands for the bottom skin, ligh ...
Assessment of existing steel structures: recommendations for estimation of remaining fatigue life. The growing importance of sustainability affects new markets for the construction industry; the rehabilitation and refurbishment of existing buildings and ci ...
A critical aspect in the design of tubular bridges is the fatigue performance of the structural joints. Economic viability depends on it. Lower fatigue strength for joints with thicker failing members was observed in welded joints typical to the bridge app ...
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 ...
The conservation of historical monuments and especially natural stone masonry arch bridges is an issue which is becoming increasingly important. The prerequisite for any analysis of the load carrying capacity of such stonework is a precise knowledge of its ...
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 ...
