Assessment of mortar and brick strength in earthquake-affected structures in Peru using a Schmidt hammer

This study describes results of surveys with Schmidt hammer conducted after the earthquake of August 15, 2007 in coastal cities of Ica, Pisco, and Chincha, Peru. Statistical analysis included comparison of data on compressive strength collected from various types of buildings in damaged and intact walls and bricks. Results of statistical analysis suggest that architecture and nonstructural building design considerations in masonry structures may be more important determinants of seismic resistance than construction material strength. Comparison of mortar samples with respect to structure ownership revealed that strength of mortar at test locations in privately owned buildings was significantly greater than in public buildings.
