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.
Highlights
The main areas of concern of structural damages are usually design deficiencies, problems during construction, material durability or compatibility and foundations (1) (2)
Structural damages and failures are frequently attributed to a series of factors rather than just a single cause as it is the example discussed in this paper
The Winter Garden (Invernadero) designed by Eduardo Torroja, is one of the singular buildings which dates from the first years of the actual Eduardo Torroja Institute for Construction Sciences (IETcc) research complex, the majority of which were built in the early 1950’s (3) (4)
Summary
The main areas of concern of structural damages are usually design deficiencies, problems during construction, material durability or compatibility and foundations (1) (2). The Winter Garden (Invernadero) designed by Eduardo Torroja, is one of the singular buildings which dates from the first years of the actual Eduardo Torroja Institute for Construction Sciences (IETcc) research complex, the majority of which were built in the early 1950’s (3) (4). It is a very interesting structure formed exclusively in brickwork with arches as the main vertical load-bearing elements and is inserted within the natural slope of the ground. The major factors of the deterioration were identified during the works and a monitoring of the crack pattern evolution during more than a year was carried out (6), further problems associated with subsidence as well as material durability can lead to complex long term deformations of the brick structural elements which need to be explored
