Textile reinforced concrete for strengthening of RC columns: A contribution to resource conservation through the preservation of structures
چکیده انگلیسی
In the context of renovation and repair work or when buildings are to be adaptively reused, the planning engineer is frequently required to strengthen the load-bearing structure. This is the case, for example, if live loads will increase due to changes in use or if the structural integrity of a building has to be restored after a fire or earthquake. Columns are particularly vital components and elements of the static system of many buildings. Their main task is to withstand axial forces. This article describes the results of experimental tests on the effect of strengthening 2 m long columns (with and without internal steel reinforcement) using textile-reinforced concrete (TRC). Two forms of strengthening were investigated: Complete wrapping with TRC along the full height of the columns and partial wrapping along 300 mm in the load introduction ranges. Findings show a maximum increase of up to 85% in load capacity compared to non-strengthened reference columns. The individual components of the load bearing properties were analysed and a simple calculation model applied.
