Design of Prestressed Concrete Part 2 – Quiz and Interview Questions

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.  In the field of bridge engineering, the introduction of prestressed concrete has aided the construction of long-span concrete bridges. These often comprise precast units, lifted into position and then tensioned against the units already in place, the process being continued until the span is complete. Test your knowledge on design of concrete elements, Prepare for GATE , IES and other examinations. This test will also help graduate candidates appearing for interviews.

The cracking moment (Mcr) is defined as the moment due to external loads at which the first crack occurs in a prestressed flexural member. Considering the variability in stress at the occurrence of the first crack, the evaluated cracking moment is an estimate. Nevertheless, the evaluation of cracking moment is important in the analysis of prestressed members.
