Pseudodynamic Tests and Numerical Modelling for Damage Analysis of Infilled RC Frames

Full-scale experimental tests are still needed to enhance knowledge on the seismic response of existing reinforced concrete buildings and to calibrate numerical models aimed at predicting damage. This study deals with pseudo-dynamic (PSD) tests and numerical modeling of full-scale multi-story infilled RC frames with different infill-to-frame connections. Nonlinear numerical models are calibrated using the experimental results at frame level and validated against the results of time-histories in terms of displacement demand, hysteretic response, and attained damage. This model is extended at building level and used to predicted damage to infills. The comparison with damage observed during post-earthquake inspections is reported and discussed.

Automated summary

This study focuses on the seismic response of existing reinforced concrete buildings and the calibration of numerical models through pseudo-dynamic tests and numerical simulations. Nonlinear numerical models are validated using experimental results and used to predict damage to infills. The results are compared and discussed with damage observed during post-earthquake inspections.
