| Summary: | This paper presents the results of an ambient vibration test conducted on a 4
stories reinforced concrete school building located in Bukit Tinggi, Bentong,
Pahang, Malaysia. The test was intended to determine preliminary
information on the dynamic properties 'of the building.' Vibration response
measurements were taken on selected locations of the building to determine
the overall modal parameters such as mode shapes, modal frequencies and
modal damping. Output-only modal identification methods, the Enhanced
Frequency Domain Decomposition (EFDD) method in frequency domain and
the Stochastic Subspace Identification (SSI) in time domain were
implemented in the estimation of the modal parameters of the building. In
addition, microtremor measurements were also conducted in the vicinity of
the building.to determine- the frequency of the site and assess the potential
effects of soil-structure interaction, which could have a significant effect on
the seismic performance of the building during earthquake. This paper
describes the building tested, the tests and results, the methodologies and the
equipment used.
