Concrete Structures with Rocking Behaviour: a Review

Damage control relevance has been increasing in the design of structures subject to seismic events. To this matter, rocking behaviour is an interesting alternative to traditional structural solutions. Rocking hybrid systems, for example, using post-tensioned tendons and energy dissipaters made of shape memory alloy materials, is a promising research field. This paper reports a bibliographic review on concrete wall structures with rocking behaviour, focussing the ability to dissipate energy while possessing recentring capacity. These two properties make it possible to efficiently control damage as well as residual displacements on structures subject to relevant cyclic actions. This type of solution is expected to significantly reduce repair costs and indirect costs associated with the downtime. Several studies were found regarding rocking wall with post-tensioned tendons and energy dissipaters, nevertheless, rocking wall with smart materials alloys need further investigation
