Pretensioned caps investigate the spacing of shear spacing, use of voids, and void detailing. Pretensioned caps exhibit significantly reduced flexure cracking, with the ability to fully close upon removal of live load. Bent caps with voids were susceptible to minor shear cracking under design loads, with minimal impact of void detailing.
The use of curved, precast, pretensioned concrete girders has many advantages as an alternative to curved, post-tensioned concrete girders and curved steel girders. This paper summarizes the current practice of horizontally curved bridge construction. A curved, precast, pretensioned concrete I-girder has the
The stress corrosion behavior of ungrouted pretensioned steel was assessed by using various electrochemical techniques such as electrochemical noise, open-circuit potential measurement, AC impedance, and potentiodynamic polarization measurements.

2020-04-11 · Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" during production, in a manner that strengthens it against tensile forces which will exist when in service.: 3–5 This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service.

When raft foundation is founded on sand, differential settlement governs the design but this is determined by the strength and stiffness of the raft structure and is very difficult to assess. Accurate estimations of all types of loads, moments, and forces are needed for the present as well as for future expansion.
