Abstract

Diante da busca por materiais mais sustentáveis, os produtos de madeira engenheirada surgem como uma alternativa para a construção de edifícios. O Cross Laminated Timber (CLT) se destaca por sua leveza, resistência e a capacidade de dissipação de energia advinda de cargas de vento e sísmicas. Essas propriedades caracterizam o CLT como um material de elevado potencial para aplicações em zonas sísmicas. Nesse sentido, tendo em vista a importância da condução de estudos experimentais a fim de avaliar o desempenho de estruturas CLT resistente à sismos, o presente trabalho teve por objetivo a realização de uma revisão sistemática da literatura acerca dos estudos experimentais em paredes de cisalhamento e oscilantes de CLT convencionais. Para isso, foi realizada uma revisão sistemática da literatura a partir de duas bases de dados: Scopus e Web of Science. Identificou-se, nos últimos anos, um aumento no número de estudos relacionados ao tema. Além disso, observou-se que são necessários mais estudos acerca de paredes de cisalhamento do tipo balão a fim de validar os poucos estudos existentes e contribuir para a compreensão acerca de seu comportamento. Adicionalmente, observou-se que os protocolos de carregamento utilizados foram as normativas ASTM E2126 (2011), EN 12512 (2005), ISO 22452 (2011), EN 594 (2011) e a ACI ITG-5.1-07 (2008). O protocolo de carregamento CUREE foi o mais utilizado, abrangendo 36% dos estudos. Dessa forma, a normativa ASTM E2126 (2011) foi a mais empregada na realização dos testes cíclicos em paredes de cisalhamento de CLT. Tendo em vista que essas normativas não foram desenvolvidas especificamente para paredes CLT, torna-se crucial a condução de mais estudos experimentais para respaldar a elaboração de protocolos de teste específicos destinados a paredes de cisalhamento CLT.
