Abstract
Since 1993 a 280m building in Singapore has been instrumented using an evolving
monitoring system that began with manual static readings of stress and strain and progressed
through a full-scale vibration survey to a permanent remote control system using basement
and roof accelerometers together with anemometers to capture the effect ...
Since 1993 a 280m building in Singapore has been instrumented using an evolving
monitoring system that began with manual static readings of stress and strain and progressed
through a full-scale vibration survey to a permanent remote control system using basement
and roof accelerometers together with anemometers to capture the effect of wind and seismic
loads. Recently a dual-rover RTK GPS system has been operating in synchronisation with the
wind and acceleration system in order to test the feasibility of GPS for building performance
monitoring and to understand the way the building responds quasi-statically to wind,
temperature and seismic loads. The paper describes the system integration for the present
monitoring system and presents some results on performance of the building and the GPS
system
