Structural appraisal of climate-induced effects on E. Torroja's unreinforced brickwork shell structure of the IETcc winter garden

Abstract

In this paper, the design and causes of deterioration of the Winter Garden located in the Eduardo Torroja Institute for Construction Sciences (IETcc) in Madrid, as well as the structural rehabilitation works carried out are discussed. The structural and architectural scheme was devised by E. Torroja and is examined using numerical analysis under dead load. This allows the failure pattern of the arches and shells to be assessed, as a consequence of water ingress through the cracks formed and settlement, as also the effectiveness of the repair techniques applied in 2009.
