An experimental evaluation of the structural health monitoring capability of piezoelectric wafer active sensors on composite structures at cryogenic temperatures is presented. The piezoelectric wafer active sensor–based electromechanical impedance and the pitch–catch methods were first qualified for cryogenic temperatures using piezoelectric wafer active sensor–instrumented composite specimens ...

Structural health monitoring is a developing research field which is multifunctional and can estimate the health condition of the structure by data analyzing and also can prognosticate the structural damages. Illuminating the damages by using piezoelectric sensors is one of the most effective techniques in structural health monitoring. Pressurized equipments are very important components in pro...

Recently, a variety of wireless structural health monitoring systems have been demonstrated as viable substitutes for traditional high-cost tethered monitoring systems. In this study, a prototype wireless sensing system is deployed on the Voigt Bridge (La Jolla, CA) and a historical theatre (Detroit, MI) to validate its performance against cabled monitoring systems. Acceleration time history re...

Structural control and health monitoring as condition are some essential areas that allow for different system parameters to be designed, supervised, controlled, evaluated during the system’s operation in processes, such those used machinery, structures, physical variables mechanical, chemical, electrical, aeronautical, civil, electronics, mechatronics, agricultural engineering applications, am...

A unique shape memory alloy (SMA) restrainer cable is developed and tested to evaluate its effectiveness in limiting the hinge opening in bridges. The SMA cables, connected at the deck–abutment interface, are tested on a four-span, one-quarter scale, concrete slab bridge. The bridge is subjected to a suite of ground motion to assess the performance of the SMAs under different magnitudes of load...
