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 کاملAn Integrated Frp Strengthening and Damping System for Multiple Performance Level Seismic Retrofit of Rc Columns
The concept of an integrated strengthening and damping retrofit system was proposed to design reinforced concrete (RC) columns for their optimal performance under multi-level earthquake hazards. As illustrated in Figure 1, the system consisted of fiber reinforced polymer (FRP) sheets wrapping around a column and viscoelastic (VE) layers on the FRP sheets. The motion of the outer surface of the ...
متن کاملSeismic Performance of Square RC Bridge Columns under Combined Loading including Torsion with Low Shear
During earthquake excitations, reinforced concrete bridge columns can be subjected to a combination of axial load, shear force, flexural moments, and torsional moments. The torsional moment can be much more significant in columns of bridges that are skewed, curved, have unequal spans, or unequal column heights. Combined loading including torsion can result in complex flexural and shear failure ...
متن کاملProbabilistic Evaluation of Seismic Performance of RC Bridges in Iran
Many existing bridges were designed without adequate consideration of seismic risk. The full or partial collapse of even one major bridge in a city or community would have destroying results. There has been focuses on developing fragility-based seismic vulnerability of existing usual bridges in Iran or support decision making on seismic upgrade. This article focuses on developing performance b...
متن کاملan investigation on seismic design indicators of rc columns using finite element analyses
the main cause of structural damage in buildings subjected to seismic actions is lateral drift. in almost all reinforced concrete (rc) structures, whether designed with walls or frames, it is likely to be the code drift limits that control the design drift. the design drift limits and their contribution to damage may be represented indirectly through the material strain limits. the aim of this ...
