Displacement‐Based Seismic Design Procedure for Framed Buildings with Dissipative Braces Part I: Theoretical formulation
The insertion of steel braces equipped with dissipative devices proves to be very effective in order to enhance the performance of a framed building under horizontal seismic loads. Multi‐level design criteria were proposed according to the Performance‐Based Design, in order to get, for a specific level of the seismic intensity, a designated performance objective of the building (e.g., an assigned damage level of either the framed structure or non‐structural elements). In this paper a design procedure aiming to proportion braces with hysteretic dampers in order to attain, for a specific level of the seismic intensity, a designated performance level of the building is proposed. Exactly, a proportional stiffness criterion, which assumes the elastic lateral storey‐stiffness due to the braces proportional to that of the unbraced frame, is combined with the Direct Displacement‐Based Design, in which the design starts from target deformations. A computer code has been prepared for the nonlinear static and dynamic analyses, using a step‐by‐step procedure. Frame members and hysteretic dampers are idealized by bilinear models.
