“…Several monitoring programs are running all over the world providing valuable data that are currently used for development and validation of damage identification methods, to assess the bridge performance, to provide real-time information for safety assessment in the aftermath of an extreme event (e.g. Mufti 2002, Smyth et al, 2003, Pezeshk at al 2004, Ko and Ni 2005, Celebi, 2006 After an earthquake, basing on the responses retrieved from the sensors and applying appropriate damage detection techniques, a quick assessment of the damage state of the bridge can be obtained. In the last twenty years significant technological progress has been made in the area of commercially available innovative sensors (e.g.…”

Abstract. When dealing with asset management of infrastructural systems, maintenance planning of bridges and other critical structures has to be thought against natural deterioration due to environmental conditions, but also taking into account potential criticalities induced by the occurrence of seismic and flood hazards. The aim of this work is to focus on potential damage scenarios, assessment methods for common bridge structures potentially subject to earthquake loading and scouring phenomena due to flooding hazards.

“…For longer term measurements as part of a bridge structural health monitoring (SHM) system (Ko and Ni 2005), fewer accelerometers can be deployed, particularly where a modal survey has provided a set of vibration modes (Brownjohn et al 2010) that can be used as a basis set for mapping a minimal set of measurements to a complete structure. Conversely identification of the more complex quasi-static three dimensional deformation patterns requires a more extensive set of instrumentation.…”

The Shanghai Tower, currently being constructed in Shanghai, China, is a supertall building with a height of 632 m. The Shanghai Tower will be the tallest skyscraper in China after its completion. This structure consists of a core wall inner tube, an outer mega-frame, and a total of six levels of outriggers that connect the tube and the frame.The structure needs comprehensive full-scale investigation to understand its structural performance when subjected to dead loads, strong winds, earthquakes, and temperatures, given its supertall height and complex structural configuration. A sophisticated structural performance monitoring system that consists of more than 400 sensors is designed for both in-construction and in-service real-time monitoring of the skyscraper. This is the Pre-Published Version.This paper reports the structural system and provides details on the performance of the monitoring system. The key features of the monitoring system are the following: (1) simultaneous installation of sensors and data acquisition systems with structural construction to record initial values; (2) measurement of structural settlement and displacement at different construction stages; (3) direct measurement of wind loads on structure facades through 27 wind pressure sensors; and (4) measurement of structural inclination and derivation of structural sway at different heights using 40 inclinometers.Preliminary monitoring data, which include deformation and strain/stress up to the present construction stage, are also presented and discussed.
