Abstract

Ping‐An Finance Center (PAFC), with a total height of 600 m, is the fourth tallest building in the world. An integrated structural health monitoring (SHM) system with total number of 553 sensors, which was designed based on the modular design methodology, is being installed in PAFC to monitor its structural performance and external excitations during both construction and service stages. This paper first gives a brief introduction of the architecture of the SHM system, followed by detailed descriptions on its 7 subsystems, including the components, functions, and interrelationship corresponding to each subsystem. The modular design of the SHM system ensures highly effective operation of the comprehensive monitoring system, and such an extensible system allows the subsystems to be deployed and augmented easily to meet the evolving monitoring needs. The second part of this paper introduces the research activities and selected results from the SHM system equipped in PAFC, including monitoring of vertical deformations of various structural components, verification of effectiveness of active tuned mass damper systems, and verification of numerous damage identification methods. Finally, representative monitoring results from the SHM system in PAFC during a typhoon are presented and discussed. This paper aims to provide useful information for the SHM, construction, and design of super‐tall buildings.
