“…These mechanisms have to be avoided, because they involve non-dissipative zones, so that the energy dissipation capacity is reduced. A simple criterion to avoid a type-B mechanism at each storey is suggested in a companion paper [13], but anyway it is not sufficient to guarantee the desired mechanism of global type. Therefore, in this paper a design procedure aimed at dimensioning EBFs failing in global mode is proposed.…”

“…With reference to this issue, in order to calculate the virtual internal work, links are modelled as elements with plastic hinges in simple bending by means of the equivalent moment (M eq ) introduced by the same Authors in a companion paper [13]. This tool takes into account the mechanical behaviour of the link (short, intermediate or long according to the usual link classification [14]) and allows one to provide a unique formulation for the internal virtual work.…”

“…In this paper, a design methodology aimed at the failure mode control, already successfully applied with reference to MRFs [1,2], CBFs [3,4] EBFs [5,6] and KBFs [7], has been implemented for MRF-CBF dual systems. In addition, structures with different number of storeys (4, 6 and 8) have been dimensioned according to the described design procedure.…”

In particular, sophisticated design procedures assuring a collapse mechanism of global type have been already successfully developed with reference to moment-resisting frames (MRFs) [1,2], concentrically braced frames (CBFs) [3,4], eccentrically braced frames (EBFs) [5,6] and knee braced frames (KBFs) [7].…”

Abstract:In this paper, a new method for designing moment resisting frame (MRF) -concentrically braced frame (CBF) dual systems failing in global mode is presented. Starting from the analyses of the typical collapse mechanisms of such structural typology subjected to seismic horizontal forces, the method is based on the application of the kinematic theorem of plastic collapse. Beam and diagonal sections are assumed to be known quantities, because they are designed to resist vertical loads and horizontal forces, respectively. Therefore, the column sections are the only unknowns of the design problem. Column sections are obtained by imposing that the equilibrium curve corresponding to the global mechanism has to lie below all the equilibrium curves corresponding to the undesired collapse mechanisms within a displacement range compatible with the local ductility supply of dissipative elements. Such procedure has been applied to design several MRF-CBF dual systems and has been validated by means of non-linear static analyses aimed to check the actual pattern of yielding.

ABSTRACT:In this paper a design methodology aiming at the development of a collapse mechanism of global type for seismic resistant knee braced frames is presented. The proposed methodology is based on the assumption that the beam, brace and knee sections are known, while the column sections constitute the unknowns of the design problem. The design requirements are derived by means of the kinematic theorem of plastic collapse. In particular, column sections are obtained by imposing that the mechanism equilibrium curve corresponding to the global mechanism has to lie below those corresponding to all the undesired mechanisms within a displacement range compatible with the local ductility supply of knee elements.The proposed design procedure has been implemented in a computer program and applied to design some knee braced frames. Successively, static and dynamic non-linear analyses have been carried out aiming at the evaluation of the performance of the designed braced frames in terms of collapse mechanism developed under seismic forces, energy dissipation capacity and global and local ductility demands.
