Abstract

This is the 2010-2011 annual report of the NEESR Payload: Damage Detection of Reinforced Concrete Columns Subjected to Combined Actions project. This four-year project was initiated on September 1st, 2007. The goals of the project were 1) to verify smart aggregate technology, that have been recently developed by the project investigators at the University of Houston (UH), for damage detection of RC columns under dynamic, pseudo-dynamic, and reversed-cyclic loading conditions, and 2) to quantitatively study damages in the RC columns under these three different loading conditions by correlating the structural health monitoring (SHM) results of the smart aggregate based-approach with the health monitoring results of conventional approach including visual inspection and measurements from LVDTs, strain gauges and load cells. The intent of this research project is to further explore the knowledge of smart aggregates developed at UH at the practical level so that they can be widely implemented in the industrial application. In this report, at this point of the project, RC columns were tested under the reversed cyclic load and dynamic seismic load. The experimental results show that the proposed aggregate-based approach is capable to evaluate the damage severity and provide the critical examination of the reinforced concrete columns.
