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
