This paper aims to provide an experimental support on seismic performance evaluation of the steel braced truss-RC (reinforced concrete) column hybrid structure, which could be applied as the air-cooled supporting structural system in large-capacity thermal power plants located in strong earthquake prone regions. A series of pseudo-dynamic tests (PDTs) and quasi-static tests (QSTs) were performe...

Abstract Shear dampers are known as famous seismic passive energy devices due to their suitable performance against loading improve the behavior of Concentrically Braced Frames (CBFs). The CBF system suffers from low ductility its compression member's susceptibility buckling. By adding shear directly diagonal element members CBF, prevent bucking and system. Although pertain high dissipation cap...

the objective of this review to be submitted in two independent parts, for steel frames and for rc frames, is to compare their structural performance with respect to the proposed n2-method, and so also of the consequent convenience of using pushover methodology for the seismic analysis of these structures. a preliminary investigation is presented on a pushover analysis used for the seismic perf...

This paper presents an optimization-based method for computing a minimal bounding ellipsoid that contains the set of static responses of an uncertain braced frame. We assume that the parameters both of brace stiffnesses and external forces are uncertain but bounded, which is a non-stochastic model of uncertainty. A brace member represents the sum of the stiffness of the actual brace and the con...

This paper proposes a simplified analytical model for seismic response prediction of concentrically braced frames. In the proposed approach, a multistory frame model is reduced to an equivalent shear-building one by performing a static pushover analysis. The conventional shear-building model has been improved by introducing supplementary springs to account for flexural displacements in addition...
