Seismic Confinement Design for Rectangular Columns With Considering Shear Effect

Confinement Characteristics of Rectangular FRP-Jacketed RC Columns

In this study, FRP jackets were investigated for their confinement effectiveness on rectangular RC columns. Thirteen reduced-scale short columns were tested to failure in axial compression. Variables investigated include: the type of fibers (AFRP, CFRP or GFRP), the thickness of the jacket, the aspect ratio of the rectangular cross section and the radii of the corners. For square columns, GFRP ...

Shear wall effect on material consumption based on seismic design

The question of material consumption is one of the most important issues in seismic design of multi-story frames. The paper illustrates how material consumption can be reduced by utilizing shear wall according to the Performance-Based Seismic Design (PBSD). For this purpose, different story frames with and without shear walls are designed In addition, a simple algorithm is proposed for monitori...

Combined Transverse Steel-External FRP Confinement Model for Rectangular Reinforced Concrete Columns

Recently, the need to increase the strength of reinforced concrete members has become a subject that civil engineers are interested in tackling. Of the many proposed solutions, fiber-reinforced polymer (FRP) materials have attracted attention due to their superior properties, such as high strength-to-weight ratio, high energy absorption and excellent corrosion resistance. FRP wrapping of concre...

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...
