Estudo da influência da configuração estrutural na resposta sísmica de uma estrutura de concreto armado

Abstract: Resumo Os recentes aumentos dos registros de abalos sísmicos no Brasil impulsionaram a publicação da NBR 15421:2006 [1] - Projeto de Estruturas Resistentes a Sismos - na qual são definidas as cargas sísmicas a serem consideradas no projeto em função da capacidade de dissipação de energia no regime inelástico das estruturas e da sismicidade do território brasileiro. Algumas edificações construídas antes da publicação dessa norma não foram projetadas para resistir a ações sísmicas aumentando a sua fragilidade e … Show more

“…This is due to the low occurrence of earthquakes of large magnitudes in the Brazilian territory. Among the Brazilian general studies on earthquakes, some can be cited: Pereira et al [16] evaluates the seismic reliability assessment of a reinforced concrete (RC) frame designed in accordance with ABNT NBR 6118 [17] without considering the seismic design prescribed by ABNT NBR 15421 [3]; Aguero et al [18] proposed a structural retrofit method for evaluation of a RC casing in columns with increase in bending moments under seismic loads; Matos [19] and Alva et al [20] studied the influence of masonry on the strength of buildings subjected to seismic excitations; Gidrão et al [21] simulated seismic effects in a 12-story reinforced concrete building; Peña and Carvalho [22] studied the influence of the structural configuration on the seismic response of a reinforced concrete structure.…”
