126. Post-Tensioned Anchorage Zone Concrete Failure During Construction (I-12-SMAS-089-A)
Despite careful material selection, many unexplained catastrophic failures have been observed at anchorage zones. The current empirical models in the standard design guidelines are outdated and inadequate as they are based on properties of hardened concrete. The proposed research project is aimed at developing a novel approach to the design of post-tensioning anchorage zones for early age concrete. Post-tensioning technology is commonly used in construction industry with advantages such as reduction in usage of materials and increase in efficiency of structural systems. A more reliable design approach would benefit the construction and consulting industries and encourage the adoption of high-performance and sustainable materials.
