Stress Analysis in Masonry Walls by Ultrasonic Measurements

  • Renato S. Olivito

Abstract

Non-destructive methods play an important and active role in estimating the state of preservation of brick masonry in buildings of historical interest.

This paper describes a method of measuring the compressive strength of brick masonry walls by means of simple ultrasonic measurements carried out on a selection of the bricks themselves.

A series of preliminary ultrasonic tests was conducted on individual bricks and on brick masonry models, measuring pulse velocity with a commercially available ultrasonic unit.

After processing this experimental data a correlation was obtained between the com-pressive strength and the indirect ultrasonic velocity of brick.
