This project aims to design post-tensioning anchorage zones for early age concrete. Post-tensioning of concrete is a common construction method in Australia and worldwide. Despite careful material selection, many unexplained catastrophic failures happen at anchorage zones. Current empirical models in the standard design guidelines are outdated and inadequate, because they are based on the properties of hardened concrete. A more reliable design approach is expected to benefit the construction and consulting industries, encourage the adoption of high-performance and sustainable materials, improve community safety, and reduce the environmental effect.

本项目旨在为早龄期混凝土设计后张法锚固区。混凝土后张法在澳大利亚和世界各地都是一种常见的施工方法。尽管对材料进行了仔细的选择，但锚固区仍发生了许多无法解释的灾难性故障。目前的标准设计指南中的经验模型是过时和不足的，因为它们是基于硬化混凝土的特性。预计更可靠的设计方法将使建筑和咨询行业受益，鼓励采用高性能和可持续材料，改善社区安全，并减少对环境的影响。
