As an application part of the preceding papers (III) (IV), in which an evaluation method of the aseismic capacity of steel structures with symmetric and asymmetric braces was proposed, in this paper, the aseismic characteristics of such structures and the aseismic effects of bracing elements are investigated on the basis of their resonance-fatigue-characteristics. The aseismic characteristics of bracing elements and of structures with symmetric braces in plan are shown in the λ-η plane (Fig. 7) and in the γ-b plane (Fig. 9), respectively. The resonance-response behaviors of structures with asymmetric braces are calculated and presented in Fig. 18 as case studies. Concluding remarks are that bracing elements are effective enough to make steel structures rigid type which resists erthquake excitations through capacity and that there still remain some unbalancing risks even if two bracing elements are arranged symmetrically and separatively far from one another.
