Abstract:

The proposed steel–wood composite bridges incorporate longitudinal steel girders which are composite with wood deckings consisting of longitudinal laminates. The laminated decking is usually transversely prestressed. By orienting the laminates longitudinally, advantage can be taken in longitudinal bending of the dominant modulus of elasticity of wood. The paper shows that the load-carrying capacity of an existing slab-on-girder bridge with steel girders and deteriorated noncomposite concrete deck slab can be considerably enhanced by using the proposed system. The paper presents results of stat

This article discusses the non-linear analysis and design of highway composite bridges with profiled steel sheeting. A three-dimensional finite element model has been developed for the composite bridges, which accounted for the bridge geometries, material non-linearities of the bridge components, bridge boundary conditions, shear connection, interactions among bridge components and bridge bracing systems. The simply supported composite bridge has a span of 48 m, a width of 13 m and a depth of 2.3 m. The bridge components were designed following the European code for steel–concrete composite br

Abstract:

During the past decade, composite steel-free deck bridges came to reality in Canada through the construction of five bridges. The new structural system enables the construction of a concrete deck that is totally devoid of all internal steel reinforcement. Traditionally, reinforced concrete bridge decks are designed to sustain loads in flexure. The steel-free deck bridge system develops internal compressive forces "internal arching," which leads to failure by punching shear at substantially higher loads than the flexural design load. The fibre-reinforced concrete deck is usually attached to the

Abstract:

The dynamic performance of large-span steel-concrete composite bridges with external tendons is investigated by deriving the formula of equivalent damping ratios of composite bridges, and by considering the influence of shear connectors stiffness of composite girders, external tendons, and pile-soil dynamic interactions on the dynamic properties of steel-concrete composite bridge. Finite element analysis indicates that the equivalent damping ratio has a significant influence on the dynamic response and damping coefficient adjusted must be conducted in structural dynamic analysis.

Abstract Steel-concrete composite structures have been used in bridge engineering from decades. This is due to rational utilisation of the strength properties of the two materials. At the same time, the reinforced concrete (or prestressed) deck slab is more favourable than the orthotropic steel plate used in steel bridges (higher mass, better vibration damping, longer life). The most commonly found in practice are composite girder bridges, particularly in highway bridges of small and medium spans, but the spans may reach over 200 m. In larger spans steel truss girders are applied. Bridge compo

The steel box girder bridge has excellent applicability to curved bridges owing to its large torsional rigidity. In addition, because the weight of the segments is smaller than that of concrete bridges, it also has many applications for medium-range bridges. However, when a bridge with a span greater than 70 m is constructed, the height of the steel box girder increases, which is disadvantageous for the manufacture and transportation of girders and for bridge construction.

The presence of a crack in civil structures has a significant effect on their vibrational characteristics. The objective of the current research is to investigate the effect of crack on vibrational characteristics of bridges using FE simulation. The CAD modeling and modal analysis are conducted using ANSYS software. The natural frequencies are computed and mode shape is generated for each frequency. Then I shaped a girder with the crack that has lower natural frequencies as compared to bridge design without crack. The deformation obtained for bridge deck with cracked I-shaped girder beam is hi

Abstract:

In Austria last years sequenced according modern technology successfully bridges were made from UHPC or UHPFRC [1], [2], [3]. A couple of well-done examples of these bridges I presented on the occasion of Prof. Sparowitz birthday publication in 2017 [2]. Recently in Austria another example of a railway bridge consisting innovative material UHPFRC - created as a composite construction - was projected by ZKP ZT GmbH by order of Austrian Railway Company ÖBB. Innovative and new is the application of Ultra-High Performance Concrete in combination with Steel S355J2+N creating a composite action in

Abstract:

In order to take into account the dynamic effects of moving vehicles, bridges are designed to carry static loads that are increased by dynamic impact (IFs) factors (or dynamic amplification factors) that are a function of either the span or the first flexural natural frequency of the bridge. However, this approach tends to produce very conservative designs as the IFs are calculated based on a relatively few general parameters, ignoring many significant bridge and truck dynamic characteristics. This paper presents a method for determining more realistic dynamic impact factors for skewed composi

Abstract:

Most large-diameter concrete-filled steel tube (CFST) arch bridges adopt spiral-welded steel tubes for technical and economic reasons. However, during the steel tube manufacturing process, the welding temperature and other factors lead to a decreased spiral-welded seam (SWS) strength initially. Furthermore, for the CFST arch bridges using ordinary concrete, the laitance and air void defects inevitably appear, especially 20 years ago when there was no air-entraining agent in China. This paper presents a group of scale model experiments and finite element model analysis of the bearing capacity o

Abstract:

The present work aimed to study the effects of temperature changes and concrete creep on I-shaped steel–concrete composite continuous girder bridges during construction and operation processes. This study combined structural health monitoring data, an ANSYS finite element simulation, and the age-adjusted effective modulus method to obtain the variation laws of temperature and internal force in composite girders. Moreover, a temperature gradient model was proposed that is suitable for bridges in Hebei, China. In addition, a concrete creep experiment under unidirectional axial compression was pe

Abstract:

Currently, the seismic designs of reinforced concrete (RC) bridges with tall piers are often accomplished following the ductility-based seismic design method. Though the collapses of the RC bridges with tall piers can be avoided, they are likely to experience major damage and loss of functionality when subjected to strong near-fault ground motions. The objectives of this study are to put forward an innovative design concept of a tall-pier system and its application in tall-pier bridges. The concept of the innovative tall-pier system is derived from the principle of earthquake-resilient structu

Abstract:

The objective of this work was to apply heuristic optimization techniques to a steel-concrete composite pedestrian bridge, modeled like a beam on two supports. A program has been developed in Fortran programming language, capable of generating pedestrian bridges, checking them, and evaluating their cost. The following algorithms were implemented: descent local search (DLS), a hybrid simulated annealing with a mutation operator (SAMO2), and a glow-worms swarm optimization (GSO) in two variants. The first one only considers the GSO and the second combines GSO and DLS, applying the DSL heuristic
