Assessment of Mortar and Brick Strength in Earthquake-Affected Structures in Peru Using a Schmidt Hammer
Publication: Journal of Performance of Constructed Facilities
Volume 24, Issue 6
Abstract
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.

Acknowledgments
We would like to express our gratitude to Dr. Julio Kuroiwa who generously provided seismic hazard maps of Ica, Chincha, and Pisco, Peru and also responded to numerous scientific enquiries. Dr. Michael Hearne from USGS provided digital data on earthquake magnitude used in Fig. 1. Our sincerest thanks to Dr. Daniel Aspilcueta and Ms. María del Pilar Zambrano Pérez from Instituto Peruano de Paternidad Responsible (INPPARES) who provided logistical support for data collection. Dr. Rebekah Green from Western Washington University provided valuable remarks for this paper. Three anonymous reviewers provided valuable comments that helped make this paper more concise and focused. The study was funded by the National Science Foundation Human and Social Dynamics Program and the Johns Hopkins Bloomberg School of Public Health Center for Refugee and Disaster Response.
