This paper presents a brief overview of performance-based plastic design method as applied to the seismic design of building structures. The method uses pre-selected target drift and yield mechanisms as key performance criteria. The design base shear for a selected hazard level is calculated by equating the work needed to push the structure monotonically up(More)
Self-consolidating high performance fiber reinforced concrete (SCHPFRC) combines the self-consolidating property of self-consolidating concrete (SCC) with the strain-hardening and multiple cracking characteristics of high performance fiber reinforced cement composites (HPFRCC) (Naaman 1987, 1996, 2003). SCHPFRC is a highly flowable, non-segregating concrete(More)
The macro-scale properties of high performance fiber reinforced cement composites (HPFRCC) depend on their stress-strain characterization under tension; hence direct tensile tests are essential for determining the fundamental tensile behavior of HPFRC composites. Most tensile tests for obtaining the tensile response of FRC composites are carried out on(More)
Addition of steel fibers to high strength concrete (HSC) improves its post-peak behavior and energy absorbing capability, which can be described well in term of toughness. This paper attempts to obtain both analytically and experimentally the efficiency of steel fibers in HSC columns with hybrid confinement of transverse reinforcement and steel fibers.(More)
