Strengthening of reinforced concrete slabs with ...

Apr 01, 2008 · The potential use of mechanically-anchored unbonded fibre reinforced polymer (MA-UFRP) system to upgrade reinforced concrete (RC) slabs deficient in flexural strength is examined in this paper. A total of six RC slabs, each having 500 mm width, 100 mm thickness, and 1800 mm length, were constructed and tested to failure under four-point bending.

concrete is required. In addition, it means a lower overall building height for the same floor-to-floor height. Post-tensioning can thus allow a significant reduction in building weight versus a conventional concrete building with the same number of floors. This reduces the foundation load and can be a major advantage in seismic areas. A lower ...
