Abstract
This study presents the seismic analysis of a three-storey unreinforced masonry
building that was heavily damaged during the Aigion 1995 earthquake. The
building is located a few kilometers from the fault, thus subjected to \“near field”
ground motions. Seismic analysis of the building, using an elaborate finite
element model with properties extracted from material testing of representative
structural members and excitation from records obtained from a nearby station,
revealed the mechanism of partial failure of the top floor as well as the
weaknesses of the original building design and construction. Alternative retrofit
and strengthening techniques that can be implemented while maintaining the
architectural and aesthetical appearance of the historic building are presented.
Keywords: seismic analysis, retrofit of masonry building, near-field seismic
motion.
1 Introduction
The city of Aegio has suffered several strong earthquakes through the years. The
most recent powerful earthquake which caused human losses occurred on June
15, 1995. It was an 6.4 Ms shallow depth earthquake with an epicentral distance
of about 18 kilometers southwest of Aegio that caused the death of 26 people,
massive, and in many cases, irreparable, damages to both modern and older
(masonry) buildings [1]. In 1997 a weaker earthquake caused additional damage
on already deteriorated buildings.
Keywords
seismic analysis, retrofit of masonry building, near-field seismic
motion.
