Assessment of cantilevered concrete balconies by means of practically oriented evaluation tools

Facing the aging building stock, challenging times can be expected with a sharp increase of reinforced concrete buildings requiring maintenance, repair and/or replacement. For condition assessment existing structures an in-depth and reliable inspection strategy evaluation is essential to come durable service-life extending strategy. A stepwise protocol evaluate remaining bearing capacity cantilevered (RC) balconies presented in this paper. Corrosion causing reduction steel section, incorrect positioning reinforcement higher loads are main reasons service life might not reached or failure balcony occur. As mentioned EN 1504-9 NEN 8700, adequate diagnosis prior showing cause extent damage important (i) determine actual capacity, (ii) make estimation residual lifespan (iii) select technique define maintenance requirements. In paper newly developed for RC high-rise residential demonstrated. semi-probabilistic method used by applying partial safety factors based on Eurocode guidelines fib Bulletin 80. The structure determined NEN2767 regulations. corrosion contributor degradation structures, chloride contaminated damaged selected as case study order demonstrate applicability tools.
