Fiber-reinforced polymers (FRPs) are widely used as composite materials in civil engineering applications to rehabilitate or strengthen reinforced-concrete structural elements. The purpose of this study was compile an extensive and up-to-date experimental database based on the compressive tests conducted circular confined concrete elements using FRP materials. Strict criteria were implemented d...

Waters’ variant of the Boneh-Boyen IBE scheme is attractive because of its efficency, applications, and security attributes, but suffers from a relatively complex proof with poor concrete security. This is due in part to the proof’s “artificial abort” step, which has then been inherited by numerous derivative works. It has often been asked whether this step is necessary. We show that it is not,...
