Experimental Study on the Seismic Capacity of Anchored Brick Veneer on Nonstructural Masonry Walls

Abstract

The seismic performance of anchored brick veneer with a newly developed tie metal assembly in the nonstructural masonry wall was evaluated experimentally in this study. The test specimens were manufactured with dimensions of 2.2 m × 2.02 m. The experimental variables were the arrangement of the tie metal assembly (orthogonal or staggered), the spacing of the tie metal assembly, and the size of the vertical locking bars. All the test specimens with tie metal assemblies were capable of supporting the equivalent static load based on the Korean Building Code, and retained a drift capacity of more than 2% corresponding to the performance level of life safety. The vertical locking bars improve the seismic performance of anchored brick veneer moderately, and the recommended spacing of the tie metal assembly is 800 mm × 400 mm.
