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 ...
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 ...
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 ...
This paper presents a new concept for a lightweight hybrid- FRP bridge deck. The sandwich construction consists of three layers: a fiber-reinforced polymer composite (FRP) sheet with T-upstands for the tensile skin, lightweight concrete (LC) for the core a ...
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 ...
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 present research on cut-and-cover tunnels gives a theoretical contribution to the understanding of the behaviour of these structures up to their ultimate limit state. A simplified method inspired on the convergence-confinement method is investigated an ...
This paper presents the theoretical basis and the main results of an analytical model that describes the pre– and post–yield response of bond in reinforced concrete, as well as its influence on the behavior of structural members. The model is based on a nu ...
The effect of wood fiber anisotropy and their geometrical features on wood fiber composite stiffness is analyzed. An analytical model for an N-phase composite with orthotropic properties of constituents is developed and used. This model is a straightforwar ...
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 ...
