The response of bridges subject to fire is an under researched topic despite the number of bridge failures caused by fire. Since available data shows that steel girder bridges are especially vulnerable to fire, this paper ...
The temporary supports erection method is a fast and economical way of building cable-stayed bridges. In this method the bridge deck is first erected on a set of temporary and permanent supports and then, the stays are ...

[EN] During a fire, columns on the perimeter of a building will be subject to moments induced by both a thermal gradient and the restraint of axial expansion by adjacent heated beams, which themselves develop axial load. ...
This paper proposes a new and innovative algorithm, the Direct Algorithm (DA), which introduces, for the very first time, the unstressed length of the stays concept into the modeling of the construction process of cable-stayed ...
[EN] This paper presents an overview of fire hazard in bridges. A detailed review of actual fire incidents, case studies related to fire hazards, and post-fire assessment and repair strategies in bridges is presented and ...
Traditionally the construction process of cable-stayed bridges is modeled according to the backward approach, as its calculation is much easier using an elastic analysis. In this approach the bridge is disassembled according ...
Linkages have been widely used in machines and deployable structures, but these mechanisms have rarely been employed in the design of movable bridges. This paper explores the use of linkages both to actuate the kinematic ...
