Abstract:
An ongoing study investigating the response of a reinforced concrete building rehabifitated after the 1985 Me&% City earthquake is presented. As part of this program, the behavior under cyclic loads of reinforced concrete columns rehabilitated with steel jackets made of angles and straps is king experimentally assessed. First results on the response of the budding and on the behavior of rehabilitated columns are shown. So far, Building BL has responded elastically, with no damage under recent events. It is apparent that BL response follows the soil fundamental frequency. A first look at the behavior of steel jackets made of angles and straps Wugh two column units, indicates that strength and energy dissipation capacities can be improved, especially in undamaged columns.
