Analytical Study of Reinforced Concrete deck slab bridge with varying Span & Thickness

A bridge is a building that creates a safe path over a
river or valley while also removing an obstruction from the
way and providing passage without collapsing. A passageway
may also be necessary for a viaduct, a railroad, a crossdrainage structure like a canal or an aqueduct, among other
things. The length of bridges ranges from a few metres to
several kilometres. They are among the biggest systems ever
created by humans. The demands on materials and design are
way too high. A bridge needs to be strong enough to support
both its own weight and the weight of the people and vehicles
that cross it. The building must also withstand a number of
natural disasters, such as earthquakes, powerful winds, and
temperature changes. In this paper, we completed our work on
a two-lane, three-span bridge. T beams were taken into
consideration as integral components of the slab, as well as the
span's length and the thickness of the deck slab, for parametric
analysis. The deck thickness ranges from 150mm to 300mm
with a 50mm space in between, and the span lengths are 10, 15,
and 18 metres. For IRC Class AA loading, which is tracked
vehicle loading, a total of 12 bridge models were created and
examined. The outcome is formed by node displacement, slab
deflection, stresses in the deck slab, stresses and bending
moments in the longitudinal and cross girders
