Buildings and Structures under Extreme Loads

Exceptional loads on buildings and structures may have different causes including high-strain dynamic effects due to natural hazards man-made attacks and accidents as well as extreme operational conditions (severe temperature variations humidity etc.). All of these aspects can be critical for specific structural typologies and/or materials that are particularly sensitive to external conditions. In this regard dedicated and refined methods are required for their design analysis and maintenance under the expected lifetime. There are major challenges related to the structural typology and material properties with respect to the key features of the imposed design load. Further issues can be derived from the need for risk mitigation or retrofit of existing structures as well as from the optimal and safe design of innovative materials/systems. Finally in some cases no appropriate design recommendations are available and thus experimental investigations can have a key role within the overall process. In this Special Issue original research studies review papers and experimental and/or numerical investigations are presented for the structural performance assessment of buildings and structures under various extreme conditions that are of interest for design.
