Strong Motion Instrumentation in the British Virgin Islands

Abstract eng:
This paper describes recent strong motion instrumentation activities carried out within a collaborative agreement between The Puerto Rico Strong Motion Program (PRSMP) and the Department of Disaster Mitigation of the Government of British Virgin Islands (BVI). The instrumentation activities involved installation of four free field strong motion stations and the instrumentation of two structures [2]. The paper also presents an overview of the seismic setting of the BVI. The instrumentation efforts hope to improve the capability of BVI to respond to a natural hazard such as an earthquake. This article also presents details of the seismic analysis carried out in the design of the instrumentation scheme for one of the instrumented structures. This analysis included dynamic analysis with models calibrated with ambient vibration modeling. The analytical work was used to select the location of the instruments and to assess the seismic vulnerability of the structure.
