Resumen

O trabalho analisa a evolução de recalques do edifício Hyde Park Cavalry Barracks, em Londres, partindo de simulações numéricas axissimétricas em elementos finitos. A edificação apresenta uma fundação do tipo radier estaqueado, construído sobre uma espessa camada de argila, representada pelo modelo constitutivo Cam-Clay modificado. Dados da obra e parâmetros do solo foram obtidos através dos trabalhos de Hooper (1973) e Gasparre (2005). A sequência de etapas construtivas da fundação foi considerada e os recalques previstos foram comparados com dados de monitoramento e com as previsões numéricas de Hooper (1973), Hain e Lee (1978), Sales et al. (2010) e Bernardes et al. (2019). A análise proposta difere daquelas publicadas anteriormente por não utilizar parâmetros do solo retroanalisados dos dados de monitoramento de recalques da edificação. Os resultados indicam razoável concordância entre os valores previstos e medidos, ressaltando a escolha adequada do modelo constitutivo Cam-Clay modificado e a importância da definição da inclinação da reta de recompressão na análise de argilas muito sobreadensadas.
