Abstract: 
The objective of this study is to evaluate the seismic performance of the steel plate -reinforced high performance fiber reinforced cementitious composites (HPFRCC) coupling beams under cyclic loading and to investigate the influence of cementitious composite properties, particularly strain hardening and multiple cracking, on the damage tolerance of coupling beams when subjected to large displacement reversals. The evaluation and quantification of damage tolerance was conducted through the use of seismic damage indices. The combination of a ductile cementitious matrix and steel plate for shear reinforcement is found to result in improved energy dissipation capacity and inelastic deformability of shear dominant coupling beam. Test results showed that the steel plate reinforced coupling beam constructed with HPFRCC exhibited excellent strength, deformation capacity, and damage tolerance capacity, in comparison with steel plate reinforced coupling beam constructed with a conventional concrete.
