Summary
The effects of extreme loads like fire and blast on RC structures is described and analyzed with different models and approaches. The course will enable the students to use simplified methods in the thermo-mechanical analysis of RC structures under blast and fire loading, taking care of the field of applicability of each method.
Description
Both basic and advanced topics concerning fire and blast effects on reinforced concrete (RC) structures are treated in this course, which is organized in two modules.
The first module deals with fire in RC structures, through an overview of significant real fires and of reduced or full-scale fire tests, with an in-depth discussion on materials behaviour at high temperature.
The main differences between the standard and advanced approaches in modelling the fire scenario are discussed as well. Then, the steps required by the thermo-mechanical analysis of RC structures are covered for different levels of approximation with an application to a case study.
The second module is focused on the behaviour of reinforced concrete members under blast loading. The steps necessary to build up a reliable nonlinear dynamic model are analysed, considering the possible collapse scenarios and particularly flexural failures. The numerical methods necessary to solve the problem are. presented with a detailed analysis of the algorithms, inclusive of their implementation. A comparison between simplified and advanced models is provided as well, to highlight the advantages and disadvantages of the various approaches.
The course will enable the students to use simplified methods in the thermo-mechanical analysis of RC structures under blast and fire loading, taking care of the field of applicability of each method.
A final test is required for students who need the formative credits.
