An experimental study is conducted on three ½ scales, single-story, single-bay, frame specimens. The first specimen was a reinforced concrete frame with solid-brick infill. The second specimen was a reinforced concrete frame with hollow clay perforated-brick infill. The last specimen was a reinforced concrete frame without any infill. These three specimens were tested by pseudostatic method. Di...

ABSTRACT: The object of this paper is to identify the optimal combination of hysteresis-model and damping parameters that lead to the best correlation between the calculated and measured seismic response. The combined effects of five parameters are investigated: initial stiffness, bond-slip deformations, post-yield stiffness, unloading stiffness, and type of damping. The first four of these par...

Concentrically braced frames (CBFs) are one of the efficient lateral load resisting systems in high seismicity regions. One of the common problems with the use of concentrically braced frames is limitation in the architectural application and position of the openings. Two-story X braced frames have more advantages than other configurations of concentrically braced frames, since in many cases th...

in this paper the rehabilitation of concrete structures with a new system is considered. in this system pre- stressed cables with energy dissipating viscous spring dampers at the end of each cable, are used to increase structure lateral stiffness. cable system can be replaced with other system due to their high tensile resistance, their easy replacement, high speed performance, economical matte...

in this article, we tried to emphasis in how the range of torsionally stiff and flexible single story buildings works. the designed base was according to provisions of the canadian standard, 2005 nbcc. the behavior of nonlinear dynamic time history of eight building models subjected to seven horizontal bi-directional ground motions compatible with design spectra are investigated. these models c...
