Partially grouted reinforced concrete masonry (PG-RM) is a common building construction system in low and moderate seismic areas in the US. Past research have demonstrated that partial grouting results in lower shear strength and lower deformation capacity. Shear strength reduction is recognized by TMS 402 Masonry Code by using a gamma factor equal to 0.75. Recent NSF funded research conducted at Drexel university, University of Minnesota and University of California-San Diego aimed at finding solution to improve the strength and deformation capacity of PG-RM shear wall buildings. Successful reinforcement detail was introduced that resulted in improved shear strength and deformation capacity of this type of construction. Results were verified using full-scale shake table testing of one story PG-RM building at the University of California-San Diego.
