Abstract
An instrumentation program was undertaken to monitor the movements of a multistory underground parking structure exhibiting signs of large deformation and severe structural distress including the failure of a column. The structure is a four-story reinforced concrete building with a rectangular footprint measuring 52.42 × 71.32 m. The building's structural system consists of reinforced concrete waffle slabs resting on rectangular reinforced concrete columns. The instrumentation plan included the installation of eight vibrating-wire displacement transducers to monitor displacements and 24 electrolytic tiltmeters to monitor inclinations. The instrument data was recorded hourly and read via a remote site modem connected to a datalogger. This paper describes the instrumentation program and the procedures associated with the installation of the instruments. A summary and a brief interpretation of typical measurements are presented, along with a discussion of lessons learned and recommendations for similar projects.
