This paper addresses the seismic behavior of pseudo strain hardening cementitious composite (PSH2C) coupling beams with different failure modes in hybrid coupled shear wall. Test variables included the ratio of steel coupling beam strength to beam-wall connection strength. The results show that Specimen PSH2C-SCF exhibits a better stable behavior in comparison with Specimens PSH2C-SBVRT and PSH2C-FCF.

Steel Coupling Beam

Steel truss coupling beam is a new type of steel coupling beam structure. To investigate seismic behavior of this coupling beam, low cyclic loading tests for four full-scale specimens of steel truss coupling beam are presented. The specimens are designed considering three factors which are T-stub steel, angle steel and material strength. The experimental data show that steel truss coupling beam has good ductility, and can consume a great quantity of earthquake energy. By enlarging the sections of cross abdominal trusses and chord members, bearing capacity and stiffness of the whole coupling beam are greatly increased.

Precast Elements

We doubt whether the monolithic precast concrete structure could be designed as the cast-in-place structure in high seismic intensity area. To solve the puzzle, the 1/5 scaled monolithic precast concrete structure model and cast-in-place structure model were designed and tested by shake table. Comparative analysis between them was made to better understand their seismic behavior. Based on the experimental results, the failure pattern and mechanism were different, which was concentrated damage in coupling beam and then extended to shear walls of CIPS, and the weak connections presented cracks between precast elements besides the damage coupling beam of MPCS. The natural frequency of MPCS possessed a typical feature for the weakness of connections, which was the initial one greater than that of CIPS and decreased fast after the first waves with PGA of 0.035 g. Acceleration amplifying factors presented variation trend under the different earthquake waves. The distribution of seismic response presented linearity along the height of models in plastic stage and turned into nonlinearity later for severe damage. In general, the MPCS and CIPS had similar seismic responses, except typical characteristics. And they were proven to have better seismic performance without collapse under the high-intensity earthquake waves.

Shear System

Recently, hybrid coupled shear system, where steel coupling beam couple two or more RC shear walls are frequently applied for medium and high-rise building subjected to earthquake. This paper addresses the seismic performance of PSH2C wall - steel coupling beam with stud bolts in the connection region. Test variables included stud bolts in embedded steel coupling beam and types of material, such as PSH2C and concrete, in the wall. The results show that PSH2C wall – beam connections (PSH2C-ST and PSH2C-SB) exhibit better hysteretic response than normal concrete wall – beam connections (HCWS-ST and HCWS-SB).

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.
