Abstract:
Demand for the redevelopment of existing buildings is increasing due to potential time and cost savings and a growing focus on sustainability and the environment. Condor Tower in Perth, Western Australia provides an excellent example of how innovative engineering can be used to overcome the difficulties encountered in the retrofitting of reinforced concrete structures. Condor Tower was a 9 storey office building, to which 19 storeys have been added, converting the structure into a 28 storey residential building. The design required an understanding of the load sharing behaviour between the existing concrete columns and the new concrete infill walls. The structure was expected to develop two vertical load paths as the new and the old concrete would have different shrinkage and creep characteristics. As the behaviour could not be predicted with any confidence, an investigation was undertaken. On site strain measurements have been taken over a three year period. This paper presents the results obtained to date and a simple preliminary analysis.
