Masonry walls retrofitted with natural fibers under tsunami loads

Abstract In the last decades, several tsunamis hit international coasts and engaged scientific awareness to retrofit of coastal buildings against tsunami loads. Structural design under loads is difficult due high uncertainties phenomenon. Local collapse mechanisms masonry walls, like as out plane mechanisms, have an probability flexural actions; a higher capacity can be reached using specific systems; in particular, this paper aims deepen behavior walls retrofitted with innovative systems natural fibers applied inorganic mortar matrices. The structures actions could research topic for community dealing located areas characterized by risk. Recent engineering applications demonstrated strengthening effective existing buildings. These are great interest practical low costs their sustainability. fact, lower compared synthetic allow diffusion emerging countries. first part impact constituents on structural elements strengthened has been discussed. Important results provided order improve knowledge encourage development these many applications. Finally, effects will discussed terms critical inundation depth variations before after interventions.
