Abstract
In practice, dual structural systems are frequently encountered, consisting of structural walls and reinforced concrete frames. The main problem when designing dual systems is to correctly notice the contribution of each component.
As structural engineers, we can control and improve the behaviour of constructions subject to seismic action by the way we design, conform and realize the structural system. This is also the objective of the present paper, namely, the analysis of the influence of the conformation and arrangement of the structural walls on the seismic response of buildings with a dual structural system.
