“…In 2010, some of the authors proposed the so-called five-step procedure for the design of frame structures equipped with added viscous dampers (Silvestri et al, 2010). A summary of the five-step procedure is here provided.…”

“…For more details and for all the notations which will be used hereafter, the interested reader is referred to the work by Silvestri et al (2010). It is worth noticing that, in the light of the results presented in the previous section, the original procedure can be now updated by using estimation of the dampers working velocities given by Eqs 3 and 4.…”

“…Nonetheless, other alternative approaches leading to practical design procedures for the sizing of the viscous dampers have been proposed in the last years: (i) Christopoulos and Filiatrault (2006) suggested a design approach for estimating the damping coefficients of added viscous dampers consisting in a trial and error procedure and (ii) Silvestri et al (2010) proposed a direct design approach, referred to as the "five-step procedure.

“…The original procedure (Silvestri et al, 2010(Silvestri et al, , 2011Palermo et al, 2013a) although mostly based on analytical expressions, still requires the development of numerical time-history analyses of FE models in order to estimate the maximum inter-storey velocity, necessary to obtain the maximum forces in the added dampers. This step inhibits the completion of the damper sizing relying on analytical results only, useful for preliminary design and for subsequent check of numerical results.…”

Several design methods aimed at sizing the viscous dampers to be inserted in building structures have been proposed in the last decades. Among others, the authors proposed a five-step procedure that guides the practical design from the choice of a target reduction in the seismic response of the structural system (with respect to the response of a structure without any additional damping devices) to the identification of the corresponding damping ratio and the mechanical characteristics of the commercially available viscous dampers. The original procedure requires, also at the preliminary design stage, the development of linear seismic time-history analyses for the dampers working velocities, necessary for the evaluation of the non-linear damping coefficient. In the present paper, the original five-step procedure is further simplified leading to a direct (i.e., fully analytical) procedure, which can be very useful in a preliminary design phase. The proposed direct procedure is then applied to design the added viscous dampers to be inserted in a real school building in order to improve its seismic capacity, and compared with the well-known MCEER procedure.

“…They can enhance the viscous damping of structures to more than 20-30% of critical damping (in addition to the inherent damping of structures) and decrease stresses and strains caused by the earthquake. Therefore, a number of procedures have been developed for the design of structures with FVDs [7][8][9][10]. These dampers can behave as linear or nonlinear elements.…”

There are various types of passive energy dissipation systems that are used in the seismic design of new structures and the seismic rehabilitation of existing structures. One of the most important kinds of passive energy dissipation systems, which reduce both displacements and accelerations simultaneously, are fluid viscous dampers (FVDs). Using FVDs can reduce the seismic response and improve the performance of structures during earthquake excitations and has a significant effect on the damping of structure. In this paper, Single-Degree-of-Freedom (SDOF) systems with different periods and ductility values, equipped with FVDs, are considered. In order to evaluate the collapse capacity of structures with higher precision, P-Δ effects and strength degradation are taken into account in modeling. Incremental dynamic analysis (IDA) is applied to obtain the collapse capacity of the SDOF systems under far-field ground motion records, and finally the results are investigated. It should be mentioned that the results of this study can be extended to Multi-Degree-of-Freedom (MDOF) structures.

In this paper a method for designing supplemental brace-damper systems in single-degree-of-freedom (SDOF) structures is presented. We include the affects of the supporting brace stiffness in the dynamic response by using a viscoelastic Maxwell model. Based on the study of a SDOF under ground excitation, we propose a non-iterative design procedure for simultaneously specifying both the damper and brace while assuring a desired structural performance. It is shown that to increase the damper size beyond the value delivered by the proposed criteria will not provide any improvement but actually worsen the structural response. The design method presented here shows excellent agreement with the FEMA 273 design approach but offers solutions closer to optimality.
