Frc strain
WebJan 6, 2006 · Classes of strain-softening and strain-hardening FRC are discussed by Naaman and Reinhardt [5]. The post-crack response that exceeds the first crack stress over a large strain range is modeled ... At least half of the concrete in a typical building component is used to protect the steel reinforcement from corrosion. Concrete using only fiber as reinforcement can result in saving of concrete, thereby greenhouse effect associated with it. FRC can be molded into many shapes, giving designers and engineers greater flexibility. High performance FRC (HPFRC) claims it can sustain strain-hardening up to several percent str…
