steel or composite beams are used to couple two or more reinforced concrete walls. Examples of coupling beam-to-wall connections are shown in Figures C-II-15.3 and C-II-15.4. When properly designed, each of these systems should have shear strength and stiffness comparable to those of pure reinforced concrete shear wall systems. The structural steel sections in the boundary members will, however, increase the in-plane flexural strength of the columns and delay flexural hinging in tall walls.
