In prestressed concrete, a prestress force is applied to a concrete member and this induces an axial compression that counteracts all, or part of, the tensile stresses set up in the member by applied loading.

Prestressed concrete is that concrete in which internal stresses are so induced by the application of some special technique that the stresses so developed are of opposite nature to those produced by the external loads such as dead and live loads which the member is to carry and for which the member is to be designed.

An experimental program is described in which the punching shear behavior of externally prestressed slabs is investigated, both with plain and fiber-reinforced concrete specimens. Results indicate that significant improvements in strength, ductility, energy absorption and nonbrittleness of failure can be achieved with fiber reinforcement.
Prestressed Concrete Girder Design for Bridge Structure punching resistance of prestressed concrete slab bridges book. post tensioned simply supported prestressed concrete (PC) I-girder bridges are widely used bridge system for short to medium span (20m to 50m) highway bridges due to its moderate self Slab.
Punching shear of concrete slabs, which are subject to in-plane compression, is a design issue primarily for posttensioned flat slabs and for bridge decks. With flat slabs, the compression results from the prestress, while with bridge decks, it arises from the deck’s action as a compression flange or a local compressive membrane action.

Comprehensive Design Example for Prestressed Concrete (PSC) Girder Superstructure Bridge Design Step 4 Deck Slab Design Design Step In addition to designing the deck for dead and live loads at the strength limit state, the AASHTO-LRFD specifications require checking the deck for vehicular collision with the railing system at the extreme event limit state.

The shear resistance of the critical section without shear reinforcement is given by: (3) v c = ( / γ c) k ( ρ f ck) 1 / 3 + σ cp ⩾ v min where f ck is the characteristic concrete strength in MPa; ρ is the flexural reinforcement ratio given by ρ = (ρ z ρ y) ⩽ ; and Cited by: Bridges are important structures in modern highway and railway transportation systems, and generally serving as “lifelines” in the social infrastructure systems.
Bridge engineering is a field of engineering (particularly a significant branch of structural engineering) dealing with the surveying, plan, design, analysis, construction. However, a problem concerning the punching resistance of prestressed concrete slabs still exists, with many codes of standards reflecting different results.
An examination carried out to determine the results pertaining to Eurocode 2 and ACI code of standards show both codes producing considerably comparable results.

to cracking in post-tensioned concrete box girder bridges and have been en-countered in both Europe and the United States. These problems are not limited to those of prestressed box girder bridges, but may occur in other types of struc-tures with similar conditions and de-tails.
Problems are generally attributed to poor quality control. Advantages of Prestressed Concrete: The development of prestressed concrete has opened new vistas in the construction of highway bridges.
Prestressed concrete bridges have many advantages over the reinforced concrete ones and therefore, majority of long span concrete highway bridges are now-a-days being constructed of prestressed concrete.
