Structural Damage Detection Technique of Secondary Building Components Using Piezoelectric Sensors

With demand for the long-term continued use of existing building facilities, structural health monitoring and damage detection are attracting interest from society. Sensors various types have been practically applied in industry to satisfy this need. Among sensors, piezoelectric sensors an extremely promising technology by virtue their cost advantages durability. Although they used aerospace civil engineering, application engineering remains limited. Remarkably, recent catastrophic seismic events further reinforced necessity rapid quick judgment about safe facilities. Faced with these circumstances, study was conducted assess applicability detect components stemming concrete cracks local buckling. Specifically, emphasizes caused earthquakes. After first applying them cyclic loading tests composite beam component specimens steel frame subassemblies a folded roof plate, prospective positions were also found using finite element analysis. Crack propagation buckling locations predicted adequately. The provided output when slab showed tensile or plate experienced Furthermore, expansion progression detected multiple times during tests. Results that can components, demonstrating potential inexpensive stable systems.
