Abstract:
Computer-based analysis procedures and software are finding increasing use in assessments of the strength, safety and performance of reinforced concrete structures. By capturing and applying advanced behaviour models for material and structural responses, they provide much-needed capabilities in the evaluation of damaged, deficient or deteriorated structures, or in the evaluation of structures subjected to new uses, loads, or design specifications. These capabilities are illustrated in several case studies, two of which involve forensic analyses of failed structures. However, the results from various international prediction competitions, as well as from experimental verification studies, show that currently available software tools can often be inaccurate or unreliable; as well, they are prone to misapplication in situations for which they were not intended, and misuse in general. Various cultural and technological factors have combined to create a climate change towards the adoption and use of computer-based analysis and design software; use is increasing at a precipitous rate. Nevertheless, reasons for caution in their use are numerous, and a refocused effort is required from researchers and from the developers of such software.
