Abstract

Projetar estruturas inovadoras, econômicas e resistentes a terremotos é uma grande preocupação para engenheiros civis. Neste artigo, é feita uma comparação entre o desempenho de colunas em paredes de cisalhamento em forma de L em três edifícios diferentes sujeitos a um forte terremoto. Além disso, paredes de cisalhamento com aberturas centralizadas de diferentes tamanhos também foram estudadas. O impacto da remoção da coluna e do tamanho da abertura nas tensões de compressão foi examinado. Os resultados revelaram que a influência da remoção da coluna da parede de cisalhamento em forma de L na resposta à tensão de compressão durante um terremoto alto foi relativamente menor para o edifício de quatro andares. No entanto, a influência foi significativa para os edifícios de sete e onze andares, que foram afetados pela espessura da parede de cisalhamento e pela porcentagem de abertura. Especificamente, quando os edifícios de onze andares são reforçados com paredes de 15 cm de espessura, a diferença de tensão de compressão atinge um valor de 5,40 MPa. Essa diferença de tensão se torna perceptível em uma porcentagem de abertura de 30%.
