OPTIMAL PERFORMANCE-BASED SEISMIC DESIGN OF COMPOSITE BUILDING FRAMES WITH RC COLUMNS AND STEEL BEAMS
Composite RCS building frames integrate reinforced concrete columns with structural steel beams to provide an efficient solution for the design and construction of earthquake-resisting structures. In this paper, an optimization framework is developed for performance-based seismic design of planar RCS moment resisting frames. The objective functions are defined as minimizing the construction cos...
متن کاملPERFORMANCE BASED OPTIMAL SEISMIC DESIGN OF RC SHEAR WALLS INCORPORATING SOIL–STRUCTURE INTERACTION USING CSS ALGORITHM
In this article optimal design of shear walls is performed under seismic loading. For practical aims, a database of special shear walls is created. Special shear walls are used for seismic design optimization employing the charged system search algorithm as an optimizer. Constraints consist of design and performance limitations. Nonlinear behavior of the shear wall is taken into account and per...
متن کاملretrofitting of reinforced concrete columns using steel and concrete jacketing tchnique
retrofitting structures is an important issue. structural weakness may be due to changes in design codes or defects in implementation. adding structural floors to the existing structures may also lead to the need for strengthening and retrofitting. retrofitting is possible before the earthquake or may take place as rehabilitation of damaged members after earthquake. elements such as columns in ...
متن کاملERFORMANCE-BASED SEISMIC DESIGN OPTIMIZATION OF COMPOSITE MOMENT RESISTING FRAMES WITH CONCERETFILLED STEEL COLUMNS AND STEEL BEAMS
In this paper, an optimization framework is developed for performance-based seismic design of composite moment frames consisting of concrete filled steel box columns and I-shaped steel beams. Material cost of the structure and seismic damage under severe earthquake ground motions are minimized as objective functions. Two design examples are presented to demonstrate the applicability and efficie...
متن کاملEstimation of Yield Curvature for Direct Displacement-based Seismic Design of RC Columns
Significant research efforts have been devoted in recent years to the development of displacement-based seismic design methodologies, recognizing the shortcomings of traditional, code-specified force-based design procedures. Recent advances in direct displacement-based seismic design of columns rely on the estimates of yield curvature for the determination of seismic design forces to satisfy th...
