Determination of dynamic parameters of double-layered brick arches

Abstract

Masonry arches assume a very important role in construction industry, and we find them in many historical structures all over the world. Dynamic parameters, frequency, and damping of masonry arches are defined in this paper using the Experimental Modal Analysis (EMA). Double-layered arches were built using standard hollow bricks and traditional Horasan mortar. The brick arches were tested with an impact hammer, and the arch response was measured using a laser vibrometer. Experimental tests were compared with numerical modelling in order to verify adequacy of physical models.
