Building monitoring during the partial implosion stage

The partial collapse of a building in Colombia caused severe damage to its structural components. An implosion was realized to induce the collapse of 50% of the deteriorated building. To evaluate the influence of the implosion on the remaining structure, a monitoring survey was realized using triaxial accelerometers. Time signals associated with ambient, seismic and forced vibration were obtained. A study of the records in the time and the frequency domain was made. The analysis of the information allowed determining some structural properties that were useful to calibrate the analytical model of the structure. © 2015, International Society for Structural Health Monitoring of Intelligent Infrastructure, ISHMII.
