This paper presents the application of observability technique for structural system identification 2D models. Unlike previous applications this method, unknown variables appear both in numerator and denominator stiffness matrix system, making problem non-linear impossible to solve. To fill gap, new changes are proposed linearize equations. In addition, illustrate procedure into a detailed math...

Engineering structures such as bridges, tunnels, dams or towers are beginning to approach their service lifetime. To give an example, more than 20,000 bridges in Germany currently require immediate rehabilitation; similar situations apply in other countries. Thus, efficient and cost-effective structural health monitoring systems are needed to ensure serviceability and structural safety through ...

Structural health monitoring (SHM) is a term increasingly used in the last decade to describe a range of systems implemented on full-scale civil infrastructures and whose purposes are to assist and inform operators about continued 'fitness for purpose' of structures under gradual or sudden changes to their state, to learn about either or both of the load and response mechanisms. Arguably, vario...

Structure monitoring brings new challenges to wireless sensor network: high-fidelity sampling, collecting large volume of data, and sophisticated signal processing. New accelerometer board measures tens of G acceleration. High frequency sampling is enabled by new component of David Gay. With new component, up to 6.67KHz sampling is possible with jitter less than 10s. Large-scale Reliable Transf...
