EVALUATION ON PERFORMANCE OF RC COLUMNS AND SRC COLUMNS SUBJECTED TO REPEATED HORIZONTAL FORCE

Numerical Simulation of FRP-Jacketed RC Columns Subjected to Cyclic Loading

This paper presents a study that forms part of an ongoing project on the seismic retrofit of reinforced concrete (RC) structures with fibre-reinforced polymer (FRP). In this study, a stress-strain model for FRP-confined concrete subjected to cyclic loading was implemented into OpenSees to support the performance-based design of FRP jackets for the seismic retrofit of RC columns/structures. Init...

Numerical and Experimental Investigations on the Behavior of Steel-reinforced Concrete Columns Subjected to Eccentric Loading

Steel-reinforced concrete (SRC) columns, which are classified as composite columns, became the most widely used in recent years; because of their extensive advantages over the reinforced concrete and the steel columns. In this paper, the ductility index and its influential factors were explored to investigate the behavior of SRC columns. A straightforward approach was then proposed by establish...

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...

intermediate layer effects in performance of frp-confined rc columns

the use of polymer composite (frp) as a reinforcement material for the repair and strengthening of important components of reinforced concrete structures, particularly columns, has found wide spread. in this study, the effect of intermediate layer on improving the confinement behavior of reinforced concrete columns has been investigated. to achieve the objectives of the study, 14 cylindrical re...
