The piezoelectric ceramic sensor was fixed on Glass Fiber Reinforced Plastic (GFRP) composite civil materials, using the external paste method for damage detection test. effect of depth and number cracks surface GFRP specimen signal received by studied. time-domain graph energy based wavelet packet were drawn, combining active induction packet. It is found that greater degree specimens, smaller...

The overall objective of this research project was to conduct an extensive study of the behavior and use of glass fiber-reinforced polymer (GFRP) and carbon FRP (CFRP) materials for bridge construction. In particular, GFRP honeycomb sandwich panels were used as bridge panels and steel-supported bridge deck panels and CFRP and GFRP bars were used as internal reinforcement for precast concrete br...

this paper presents an experimental study on seismic repair of damaged square reinforced concrete columns with poor lap splices, 90-degree hooks and widely spaced transverse bars in plastic hinge regions according to aci detailing (pre.1971) and (318-02) using gfrp wraps. three specimens were tested in “as built” condition and retested after they were repaired by glass fiberreinforced plastic s...

Many civil applications use square hollow sections (SHSs) as members in beam-column connections which can be vulnerable under cyclic loading. Cyclic loadings from earthquakes, wind, waves and currents affect onshore offshore infrastructure. In addition, these become structurally inadequate through incremental service loads, design/fabrication errors material property degradation over time. Due ...
