This study examines the dynamic behaviour of historic, unreinforced masonry buildings' exterior walls made of flexible diaphragms that are bent out of plane. Dynamic analyses using a streamlined two-degrees-of-freedom model (2DOF) have been used to investigate the effect of diaphragm flexibility on the displacement capacity and demand of walls in out-of-plane bending. The wall has been modelled as an assembly of two rigid bodies constrained at the top by a spring and joined by an intermediate hinge. The damping has been modelled by adding the coefficient of restitution. The 2DOF system's equations of motion have been calculated and integrated in time. A set of walls have undergone dynamic analysis using recorded accelerogram inputs and a gaussian impulse. In order to compare the responses of the wall that is simply supported and the wall that has an elastic spring at the top.
