Displacement‐Based Seismic Design Procedure for Framed Buildings with Dissipative Braces Part II: Numerical Results
For a widespread application of dissipative braces to protect framed buildings against seismic loads, practical and reliable design procedures are needed. In this paper a design procedure based on the Direct Displacement‐Based Design approach is adopted, assuming the elastic lateral storey‐stiffness of the damped braces proportional to that of the unbraced frame. To check the effectiveness of the design procedure, presented in an associate paper, a six‐storey reinforced concrete plane frame, representative of a medium‐rise symmetric framed building, is considered as primary test structure; this structure, designed in a medium‐risk region, is supposed to be retrofitted as in a high‐risk region, by insertion of diagonal braces equipped with hysteretic dampers. A numerical investigation is carried out to study the nonlinear static and dynamic responses of the primary and the damped braced test structures, using step‐by‐step procedures described in the associate paper mentioned above; the behaviour of frame members and hysteretic dampers is idealized by bilinear models. Real and artificial accelerograms, matching EC8 response spectrum for a medium soil class, are considered for dynamic analyses.
