This type of structures is seismically vulnerable and need to strengthen for preserving its historical and cultural heritage value. This study was conducted to collect preliminary information on dynamic properties of old historical unreinforced masonry buildings located in Bangladesh. A series of ambient vibration tests (microtremor records) were performed to evaluate structural dynamic properties (damping ratio, fundamental natural frequency, etc) of three old unreinforced masonry buildings including mosque and educational use occupancy. Microtermor record was taken for 30 minutes for each building. After obtaining microtremor records, random discrete technique was performed to estimate transfer function and relevant characteristics. This paper describes the buildings tested, applied methodologies, equipment used and test results. Based on experimental information, variations of dynamic properties with preliminary influence factors are discussed.
