Modern Concrete Structures: Modelling and Assessment

点击翻译按钮获取中文摘要

Reinforced concrete structures comprise much of the critical infrastructure in Canada, ranging from bridges to nuclear power plant structures, hospitals to multi-storey buildings. This infrastructure is at a mature stage, with many structures having aged and being in need of repair. In some cases, critical concrete buildings and bridges are vulnerable to loss of use or even catastrophic failure, owing to a number of factors but mostly due to inadequate maintenance over their lifetime. With governments currently facing severe economic constraints, and with the inventory of deficient concrete structures requiring repair amounting to hundreds of billions of dollars, engineers require advanced assessment tools. These tools would enable them to assess the safety and serviceability of current structures, decide which require repair, determine the most economical and effective means of repair, and properly model the performance of structures employing new innovative materials.
