Evaluation of nonlinear behavior of High Performance Fiber Reinforced Cementitious Composite (HPFRCC) Frames

Replacing of conventional concrete by High Performance Fiber Reinforced Cementitious Composite (HPFRCC) could improve tensile strength, bending strength, shear strength and other capability of behaviour such as ductility, energy absorption and toughness. Strain hardening behaviour in (HPFRCC) could...

description	Replacing of conventional concrete by High Performance Fiber Reinforced Cementitious Composite (HPFRCC) could improve tensile strength, bending strength, shear strength and other capability of behaviour such as ductility, energy absorption and toughness. Strain hardening behaviour in (HPFRCC) could result in restrict of crack and prevent from crack widening. Also, because of the high strain capacity of (HPFRCC), using this material in the beam-column connection is more attention paid by researchers. After verification of numerical models for frame using OPENSEES software and comparison with experimental results, two 2D frames with 3 and 6 stories has been created to study. These frames have been designed based on ACI 318.

Results from nonlinear static analysis (pushover analysis) show increase of lateral strength, ductility and ultimate displacement of frames containing (HPFRCC) with respect to (RC) frames. Also, using of (HPFRCC) in frames has been decreased maximum story drift ratio, maximum roof displacement and has been increased maximum base shear and story shear in nonlinear time history analysis.
