Failure Of Prestressing Steel Induced By Crevice Corrosion In Prestressed Concrete Structures
The application of prestressed concrete technology in civil structures is relatively recent. Therefore, the existing prestressed concrete members in such structure are still relatively young, and the corrosion and the concrete deterioration problems associated with this type of concrete members have became clearly evident only in the early 1980s. Damage during service, frequently appearing afte...
متن کاملPull-Out Strength and Bond Behavior of Prestressing Strands in Prestressed Self-Consolidating Concrete
With the extensive use of self-consolidating concrete (SCC) worldwide, it is important to ensure that such concrete can secure uniform in-situ mechanical properties that are similar to those obtained with properly consolidated concrete of conventional fluidity. Ensuring proper stability of SCC is essential to enhance the uniformity of in-situ mechanical properties, including bond to embedded re...
متن کاملEstimation of Prestress Force Distribution in the Multi-Strand System of Prestressed Concrete Structures
Prestressed concrete (PSC) is one of the most reliable, durable and widely used construction materials, which overcomes the weakness of concrete in tension by the introduction of a prestress force. Smart strands enabling measurement of the prestress force have recently been developed to maintain PSC structures throughout their lifetime. However, the smart strand cannot give a representative ind...
متن کاملEstimation of Tendon Force Distribution in Prestressed Concrete Girders Using Smart Strand
The recently developed smart strand offers the possibility of measuring the prestress force of the tendon from jacking and all along its service life. In the present study, a method estimating the force distribution in all the tendons of a prestressed concrete (PSC) girder installed with one smart strand is proposed. The force distribution in the prestressed tendons is formulated by the frictio...
متن کاملInfluence of changes in the prestress force on dynamic specifications of the prestressed concrete beam
Pre-stress techniques tend to increase cross-sectional capacity and optimize design. Such features have made these techniques rather popular. Over time, these structures tend to fail, and the reduction of pre-stress force over the lifetime of the structure is said to be one of the most significant destructive factors in these structures. This decrease in force occurs due to various reasons. In ...
