Seismic Performance of Reinforced Concrete Coupled Walls

Cross_coupledBeam

In the Canterbury Earthquakes it was observed that reinforced concrete coupled wall buildings displayed more strength and lower ductility in comparison to their design intent.  As an approximate method to account for axial restraint in the design of coupled walls it is recommended that a redistribution of design demands be used to reduce the coupling beam design capacity and to achieve a more desirable coupled wall behaviour.
