Heavy Steel Structure Box Girder Bridge Modular Bridge Compose Of Steel Frame And Concrete

Description

A steel box girder bridge is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises either prestressed concrete, structural steel, or a composite of steel and reinforced concrete. The box is typically rectangular or trapezoidal in cross-section. Steel box girder bridges are commonly used for highway flyovers and for modern elevated structures of light rail transport. Although normally the steel box girder bridge is a form of beam bridge, box girders may also be used on cable-stayed bridges and other forms.

Specification

It is a simple through-type bridge, that is to say a bridge with a roadway carried between two main load carrying lattice girders (trusses). The lattice girders are built-up from a number of identical panels connected end to end by pins to form a continuous stiff girder from bank to bank. Road bearers, called transoms are laid across the bottom chords of the truss panels, connecting and spacing the main girders apart and at the same time carrying stringers (secondary members) to support timber decking.

Application
Spans from 3.6m to 31m and more - for highways, railways, pathways, bicycle racks, landscaping, etc
Standardized designs - as per Indian BIS a. RC standards and codes
Heavy live loads with high overfills - capable of supporting heavy freighter aircraft and mining haulers
Smooth approaches - from earth embankments due to soil overfill, does not require any approach slab
Low life cycle costs - traffic runs on overfill and not over an exposed bridge deck
Aesthetic structures - the true arch form is accentuated.

Cost effective
Greater strength per unit area of concrete
Quality assurance, as precast girders are made off-site

Construction
For steel box girders, the girders are normally fabricated off site and lifted into place by crane, with sections connected by bolting or welding. If a composite concrete bridge deck is used, it is often cast in-place using temporary falsework supported by the steel girder.

Either form of bridge may also be installed using the technique of incremental launching. Under this method, gantry cranes are often used to place new segments onto the completed portions of the bridge until the bridge superstructure is completed.
