Steel Coupling Beam

Coupled shear walls are widely used in high rise buildings, since they can not only provide efficient lateral stiffness but also behave outstanding energy dissipation ability especially for earthquake-resistance. Traditionally, the coupling beams are made of reinforced concrete, which are prone to shear failure due to low aspect ratio and greatly reduce the efficiency and ability of energy dissipation.  For overcoming the shortcoming of concrete reinforced coupling beams (RCB), an innovative steel coupling beams called two-level-yielding steel coupling beam (TYSCB) is invented to balance the demand of stiffness and energy dissipation for coupled shear walls. TYSCBs are made of two parallel steel beams with yielding at two different levels.  To verify and investigate the aseismic behaviour improvement of TYSCB-coupled shear walls, two 1/3 scale, 10-storey coupled shear wall specimens with TYSCB and RCB were tested under both gravity and lateral displacement reversals. These two specimens were designed with the same bearing capacity, thus to be easier to compare. The experimental TYSCB specimen demonstrated more robust cyclic performance. Both specimens reached 1% lateral drift, however, the TYSCB-coupled shear wall showed minimal strength degradation. Additionally, a larger amount of energy was dissipated during each test of the TYSCB specimen, compared with the RCB specimen. Based on the experimental results, design recommendations are provided.

To enable a comparison between the shear strength of shear walls and that of reinforced concrete beams to be made, the behaviour of the latter is briefly reviewed. The findings of research projects, related to deep beams and the effects of repeated cyclic loading, are summarised. More detailed information on the shear strength of deep beams, tested at the University of Canterbury, is presented, Particular problems associated with four classes of typical shear walls of multi-storey structures are briefly highlighted. The current recommendation of the
 SEAOC code, as applied to shear walls, are critically examined and certain
anomalies, which may ensue from their interpretation, are illustrated. Areas of research, related to the full evaluation of reinforced concrete shear wall
 behaviour, are suggested. The paper concludes with a number of design recommendations which suggest themselves from this review.
