“…Takewaki [7] presented an optimization procedure to compute the optimal size and place of dampers for planar building frame using minimum transfer function. Aydin et al [8] proposed a procedure based on the base shear force to nd optimal damper distribution using the transfer functions in 2007 [7].…”

Abstract. One of the de ciencies of diagonal (X) bracing is buckling under compressive load, hence not reaching the yielding threshold and being unstable. In this numerical study, the behavior of X-shape brace was investigated, which was modi ed by Carbon Fiber Reinforced Polymer (CFRP) plates that could absorb compressive force and make it stable. This innovative brace consisted of two separate steel plates connected by CFRP sheets to each other in the middle of the compressive element. Thus, these two parts were connected by epoxy resin and bolts. In this study, Finite Element Method (F.E.M.) was used to simulate the elements of steel and ber polymers by Abaqus software under cycle loading after designing of ber layers and connection type. Also, the numerical result was compared with the normal steel brace. The result showed that the innovative brace had more e ciency under seismic response. According to this output, ductility and energy absorption increased in the innovative model (CFRP-BR), but sti ness decreased as compared with the normal steel brace.

“…La distribución óptima de dispositivos lineales (viscosos y viscoelásticos) ha sido ampliamente discutida en la literatura científica en las últimas dos décadas como lo demuestra la gran cantidad de artículos publicados (Takewaki 1997a(Takewaki , 1997b(Takewaki , 1999(Takewaki , 2000a(Takewaki , 2000bCimellaro 2007;Aydin et al 2007;Fujita et al 2010). La mayoría de los métodos de optimización están basados en la reducción de la amplitud de las funciones de transferencia de parámetros estructurales tales como la suma de las distorsiones de piso, desplazamiento y/o aceleración en el último piso y cortante basal.…”

“…In the design using linear and nonlinear viscous dampers, many useful methods have been developed (Uetani et al, 2003;Takewaki, 2007;Aydin et al, 2007;Attard, 2007;Lavan and Levy, 2010;Adachi et al, 2013aAdachi et al, , 2013b. On the other hand, in the design using hysteretic dampers, a limited number of methods has been proposed due to its complex characteristics (Uetani et al, 2003;Murakami et al, 2013).…”

A closed-form maximum elastic-plastic response is derived for a structure with hysteretic dampers under the critical double impulse as a representative of near-fault ground motion. It is shown that the classification into nine cases is possible depending on the combination of elastic-plastic responses of the structure and the hysteretic damper and the double impulse enables the derivation of the closed-form maximum elastic-plastic critical response of the controlled structure by using the energy balance in each case. It is demonstrated that the closed-form maximum elastic-plastic critical response is quite useful for finding an optimal hysteretic damper quantity depending on the input level of the double impulse.
