Dynamic tests on seven unreinforced and two reinforced brick masonry veneer panels are reported. The panels, tied to conventional timber-frame backings, were subjected to inertial loading by sinusoidal accelerations within the expected range of seismic frequencies. Variables investigated included stud spacing, veneer-tie type, and initial distribution of preformed cracking. Results indicate that properly constructed brick masonry veneers can withstand seismic
attack levels substantially in excess of that implied by NZS 4203 for Zone A, with only minor cracking.
