Reinforced concrete structures under impact and impulsive loading: recent development, problems and trends
Description
Nuclear plant facilities and other reinforced concrete structures have to be regarded as to their safety in design and construction with respect to impact and impulsive loading in order to avoid serious damage to mankind and environment. The paper gives a survey on theoretical and experimental developments currently in progress, in particular regarding airplane crash. Some new results arising out of several research programs relevant to particular problems of impact loading have been reviewed and are presented. Experimental investigation for determination of material properties of plain concrete, reinforcing steel as well as steel-concrete bond under high strain-rates are treated in this paper including theoretical approaches for the respective material laws. An outline of soft missile impact tests performed on structural members, e.g. beams and plates, to determine the load deformation or fracture behaviour is given. Furthermore, numerical models and calculations to analyse structural components and structures under impact loading were discussed. (Author)
Abstract (Portuguese)
Instalacoes nucleares e outras estruturas de concreto reforcado tem sido observadas em relacao a sua seguranca no projeto e construcao com respeito a cargas impulsivas e de impacto a fim de evitar danos serios ao homem e ao meio ambiente. Apresenta-se uma coletanea de desenvolvimentos teoricos e experimentais em andamento, em particular visando queda de aviao. Faz-se uma revisao de alguns novos resultados obtidos de varios programas de pesquisa relevantes a problemas particulares de carga de impacto. Estudam-se as pesquisas experimentais para determinacao das propriedades dos materiais de concreto plano, aco reforcado bem como vigas aco-concreto, sob altas taxas de tensao; inclui-se aspectos teoricos para as respectivas leis dos materiais. Estuda-se tambem o desempenho de testes de impacto de misseis leves em membros estruturais, i.e., vigas e placas para determinar a deformacao por carga ou comportamento da fratura. Discute-se modelos numericos para esses estudos. (E.G.)Additional details
