A FRP COLUMN FILLED CONCRETE WITH INTERNALLY CONFINED HOLLOW

摘要

The invention and exterior parts consisting of FRP, concrete filling , forming a hollow portion inside the exterior and the concrete portion will be attached to the inner surface of the inner hollow concrete filled FRP Confined Hollow pillar comprises a inner tube consisting of a steel or FRP , which constrain the concrete . ; that is, the present invention is securing ductility to prevent brittle failure of concrete portion being formed by a tube 3 chukeungryeok state within the concrete portion exterior unit by a configuration as described above , and inserting the inner tube portion , in cross section with an increase in the rigidity of the bending moment , the weight is economical in the reduction , in seismic design provides a beneficial effect , as well as the exterior part and the internal pipe consists of a FRP provides an effect of reducing the resistance and the self-weight of the corrosion resistance .
