项目摘要

The main objective of the collaboration between uOttawa and GHD is to explore the structural implications of corrosion-relatedissues in concrete parking garage structures and to simulate their behaviour using commercial structural design softwarepackages. This will include a critical assessment of limit states criteria under long-term conditions, prediction of the structuralresponse of deteriorated elements, and evaluation of structural repair and rehabilitation techniques for service life extension. Theoverarching goal of this project is to develop a practical engineering approach, based on sound fundamental and scientificprinciples, to simulate the effects of damage in reinforced concrete structures that is appropriate for use in consulting and design firms, while simultaneously contributing towards advancing the current state of the art in the academic research community.Hence, efforts will be made to take advantage of widely available design software to simplify and streamline employee training and facilitate knowledge transfer, while considering realistic damage scenarios and fundamental principles of mechanics with an understanding of the underlying causes of deterioration. Although these approaches will be initially developed for parking garage structures, they could conceivably be later modified to account for other structure types such as buildings, bridges, dams, and other infrastructure.

渥太华大学和GHD之间合作的主要目标是探索混凝土停车场结构中腐蚀相关问题的结构含义，并使用商业结构设计软件包模拟其行为。这将包括对长期条件下极限状态标准的关键评估，对恶化元件的结构响应的预测，以及对延长使用寿命的结构修复和修复技术的评估。该项目的总体目标是开发一种实用的工程方法，基于良好的基础和科学原理，模拟钢筋混凝土结构中损伤的影响，适用于咨询和设计公司，同时促进学术研究界的当前艺术状态。因此，将努力利用广泛可用的设计软件来简化和精简员工培训，促进知识转移，同时考虑到实际的损坏场景和力学的基本原理，并了解恶化的潜在原因。虽然这些方法最初将用于停车场结构，但可以想象，它们以后可以修改为考虑其他结构类型，如建筑物，桥梁，水坝和其他基础设施。
