Experimental Investigations of Seismic Stability on Masonry Walls at Beauharnois Powerhouse

Abstract eng:
Seismic stability of facade brick-masonry walls of machinery building of Beauharnis Powerhouse near Montreal, Quebec, Canada, besides applied sophisticated analytical non-linear models, is also checked by experimental methods on site as well as by 1/3 scaled model on seismic shaking table, by simulation of expected earthquakes on the powerhouse location. Dynamic properties of machinery building were obtained by ambient vibration measurement. Based on these results a model of a representative part of the building, together with very specific facade brick masonry wall was designed and constructed in IZIIS Laboratory and then tested on the shaking table. The obtained results are very reliable and in good correlation with the analytical ones, which confirm the correctness of mathematical model..
