Therefore, it is vital to assess the quantitative damage in order to estimate the residual seismic capacity of the structure and to identify actions to be taken regarding the damaged building. In countries like Japan or the United States of America there are recommendations issued by public organisations, such as the Architectural Institute of Japan and the Applied Technology Council (ATC 40) of the USA, about seismic assessment and retrofitting of concrete buildings and the estimation of the residual seismic capacity of a structure. In Argentina the present standards do not provide judgement criteria or suggestions about this matter. In addition, there is no research work that can relate experimental results with quantitative methods in order to assess the remaining seismic capacity of a structure after the seismic event. The general objective of this project is to propose a post-seismic assessment methodology of concrete buildings in order to quantify objectively the residual seismic capacity of structures after a destructive earthquake, thus providing engineers a tool to decide whether it is safe to continue using the damaged building or not (evaluating the necessity of retrofitting). The specific objectives are: to develop an in-situ form for a quick damage and safety assessment of buildings after an earthquake. To develop a post-seismic assessment methodology of concrete structures. To develop and adjust hysteretic models using experimental results in order to predict the behaviour of different types of structures (shear walls, reinforced concrete frames and masonry infilled RC frames). To determine the reduction factor of the seismic capacity of concrete elements and masonry panels according to the remaining seismic capacity and the initial seismic capacity. To determine the existing relationship between the maximum crack width (measured in-situ) and the residual deformation or drift in order to estimate the reduction factor. To calibrate a nonlinear numerical model that allows to predict the cyclic behaviour of RC frames and masonry infilled RC frames and to determine the reduction factor of the seismic capacity for different ductility levels.<\/p>\n <\/a>facu<\/span><\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" EVALUACI\u00d3N POST – SISMO BASADA EN EL \u00cdNDICE DE CAPACIDAD RESIDUAL (CIUNT 26\/E545\/1) POST-EARTHQUAKE DAMAGE ASSESSMENT BASED ON RESIDUAL SEISMIC CAPACITY Director: GAL\u00cdNDEZ, Enrique Emilio Co-Director: GUTI\u00c9RREZ, Sergio Eduardo Periodo de Ejecuci\u00f3n: Inicio 01\/01\/2014 – Finalizaci\u00f3n 31\/12\/2017 Ver Grupo de investigaci\u00f3n Resumen Luego de la ocurrencia de un sismo destructivo, es de primordial importancia decidir […]<\/p>\n","protected":false},"author":20,"featured_media":0,"parent":151,"menu_order":19,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"_links":{"self":[{"href":"https:\/\/www.facet.unt.edu.ar\/iest\/wp-json\/wp\/v2\/pages\/1383"}],"collection":[{"href":"https:\/\/www.facet.unt.edu.ar\/iest\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.facet.unt.edu.ar\/iest\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.facet.unt.edu.ar\/iest\/wp-json\/wp\/v2\/users\/20"}],"replies":[{"embeddable":true,"href":"https:\/\/www.facet.unt.edu.ar\/iest\/wp-json\/wp\/v2\/comments?post=1383"}],"version-history":[{"count":6,"href":"https:\/\/www.facet.unt.edu.ar\/iest\/wp-json\/wp\/v2\/pages\/1383\/revisions"}],"predecessor-version":[{"id":3048,"href":"https:\/\/www.facet.unt.edu.ar\/iest\/wp-json\/wp\/v2\/pages\/1383\/revisions\/3048"}],"up":[{"embeddable":true,"href":"https:\/\/www.facet.unt.edu.ar\/iest\/wp-json\/wp\/v2\/pages\/151"}],"wp:attachment":[{"href":"https:\/\/www.facet.unt.edu.ar\/iest\/wp-json\/wp\/v2\/media?parent=1383"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Resumen<\/h4>\n
