Slab and girder bridges are used when the economical span limit of solid slab bridges is exceeded.
Slab on girder bridge. Slab and girder bridges are used when the economical span limit of solid slab bridges is exceeded. For simply supported spans this limit is generally found to be nearly 10 metres and for continuous or balanced cantilever type structures this limit is 20 to 25 metres. The deck slab of a slab and girder bridge spans transversely over the girders.
An ultimate load test on a shortspan simply supported bridge having six rolledsteel girders and a noncomposite deck slab is described. The main conclusions drawn from the test are as follows. 1 The bearing restraint forces reduced the bending moment at midspan by a minimum of 11.
2 the transverse load distribution pattern of the bridge improves by a relatively small margin as the. Top PDF Slab-on-girder bridge. Load Distribution Factors for Skewed Composite Steel I-Girder Bridges This section presents an extensive parametric study in which more than 3200 composite straight and skewed slab -on- girder bridge prototypes were considered for three limit states ULS SLS and FLS using three-dimensional finite element analysis.
GIRDER AND SLAB BRIDGES Girder and slab bridges are known as beam bridges. And carry the loads which come upon them by their resistance to bending. They are extensively used for short spans and low shal low crossings.
These bridges are very interest ing as examples of the advantages of reinforced concrete construction because it is only the use of the steel reinforcement which makes it. Modelling the bridge structure. A typical slab-on-girder bridge is simply supported on columns piers or abutments Fig.
The focus of this study is on developing the SHDFEA based on the bridge structure-traffic dynamic interaction and exploring the effects of columns reinforcement corrosion damage on the dynamic behaviour of the bridge. Hence it is essential to. Under lateral load concentrates at the end diaphragms of steel slab-on-girder bridge superstructures and that the presence ofintermedi-ate cross braces does not affect the seismic behavior of these bridges and can be neglected.
This demonstration leads to a sim-plified structural model to simulate the system behavior. A simplified method for two-lane slab-on-girder bridges in Hong Kong was presented by Chan et al. This was based on HB loads that are popularly used for bridge design in the UK.
The HB loading comprises four axles with four wheels in each axle. The weights of the wheels are governed by the units of the HB loading. In Great Britainwe have 30 units 375 and 45 units of HB.
Each unit of HB is equal to 10 kN. For instance for 45 units of HB. Are girder splices required.
Splices are generally required for girders that are too long to be transported to the bridge site in one piece.

Skewed Slab-on-Girder Steel Bridge Superstructures with Bidirectional-Ductile End Diaphragms. Skewed Slab-on-Girder Steel Bridge Superstructures with Bidirectional-Ductile End Diaphragms Journal of Bridge Engineering May 2010 Impact of Diaphragms on Seismic Response of Straight Slab-on-Girder Steel Bridges. Composite steel girder bridges in the state of Tennessee.
He else displays the details of the link slab continuity for composite load details and continuity for dead load slab and composite load details. 13 Performed an analytical study of the load-deflection response of this jointless bridge. Form work of Deck slab is in progress.
Concrete composite slab-on-girder bridge superstructure for use on secondary highways by making use of glued-laminated glulam girders an ultra-high performance fibre-reinforced concrete UHPFRC deck slab and external unbonded prestressing 1. This superstructure is referred to as. Composite slab-on steel I-girder bridges are among the most common short-to-medium span bridges built in the North America 1.
Compared to concrete solid slab as well as slab-on-concrete girder bridge type composite steel bridges are lighter and having better load carrying capacity since concrete cracking does not exist in girders 2.
