Various Elements Of Bridge Structures

A bridge refers to a structure that arranges a passage over a hurdle devoid of closing the way underneath. The necessary passage will be intended for a road, a railway, pedestrians, a canal or a pipeline. The hurdle to be spanned may be a river, a road, railway or a valley.

Categorization of Bridges

Category of Bridges (based on form (or) type of superstructures)

1. Slab bridge

2. Beam bridge

3. Truss bridge

4. Arch bridge

5. Cable stayed (or )suspended bridge

Category of bridges (based on construction material of superstructure)

1. Timber bridge

2. Concrete bridge

3. Stone bridge

4. R.C.C bridge

5. Steel bridge

6. P.C.C bridge

7. Composite bridge

8. Aluminum bridge

Category of bridges (As per inter-span relationship)

1. Simply supported bridge

2. Cantilever bridge

3. Continuous bridge

Classification of bridges (Following the placing of the bridge floor compared with superstructures)

1. Deck through bridge

2. Half through or suspension bridge

Categorization in terms of method of connection of various part of superstructures

1. Pinned connection bridge

2. Riveted connection bridge

3. Welded connection bridge

On the basis of length of bridge

1. Culvert bridge(less than 6 m)

2. Minor bridge(less than 6 m-60m)

3. Major bridge(more than 60 m)

4. Long span bridge(more than 120 m)

On the basis of function

1. Aqueduct bridge(canal over a river)

2. Viaduct(road or railway over a valley or river)

3. Pedestrian bridge

SAFI Bridge is a useful construction program to Analyze & design 2D and 3D bridge models

The SAFI Bridge program is very useful for engineers to study, validate, assess, generate and design large and complicated 2D and 3D bridge models having different types and sizes on the basis of standard or non-standard moving loads. With this construction program, the engineers can validate and design steel, composite, reinforced concrete, bridges together with pre-stressed bridge girders.

The SAFI bridge analysis component of the program is based on the autonomous and customary code and it contains incomparable graphical user interface.

The SAFI Bridge program contains the following features :-

• The program accomplishes numerous simultaneous or non simultaneous standard and non standard moving  loads analysis with plain and complicated procedures.

• The program consists of a wide-ranging library containing more than 25 standard trucks and a moving load    editor for user defined trucks and trains.

• The moving loads can be transmitted to selected elements of the model.

• Impact factors are assigned for a whole truck load or following a per axle basis along with lane loads. Axles can    be expanded on the basis of some bridge design codes like the CAN/CSA S6-06 code

• Lateral distribution factors toward moment, shear and deflection are substantiated.

• Envelopes of response are procured with the integration of moving loads, lane loads and non moving loads.

• Incremental analysis is performed considering staged constructions.

• Load factors are established automatically by the program while analyzing a subsisting bridge.

• The advanced query engine is applied to determine the relevant forces and utmost values at any point of the      structure

• SAFI Bridge facilitates the query analysis results and associated results at any point of the structure

• SAFI Bridge can assess and design steel, composite, reinforced concrete, bridges together with pre-stressed bridge girders.
