摘要

This work presents the results and preliminary analysis of the Acoustic Emission (AE) as recorded during a shaking table tests carried out at the University of Granada. A reinforced concrete (RC) frame structure was subjected to earthquake-type dynamic loading on a shake table up to collapse. The peak acceleration applied to the shaking table was increased in four consecutive seismic simulations. The frame structure was designed by applying the strong column-weak beam concept and capacity considerations. The evolution of damage was monitored in terms of AE energy recorded by low frequency sensors. Moreover, a good correlation between the macrocracks and the AE source locations after each seismic simulation was observed.
