Damage localization and quantification of earthquake excited RC-frames [PDF]

Earthquake Engineering & Structural Dynamics, 1998
In the paper a recently proposed method for damage localization and quantification of RC-structures from response measurements is tested on experimental data. The method investigated requires at least one response measurement along the structures and the ground surface acceleration. Further, the two lowest time-varying eigenfrequencies of the structure

An efficient Performance-Based Seismic Design of Reinforced Concrete Frames [PDF]

, 2011
In this paper, a practical method is developed for performance-based design of RC structures subjected to seismic excitations. More efficient design is obtained by redistributing material from strong to weak parts of a structure until a state of uniform ...

Efficient Behavior Factor Estimation in Moment-Resisting Reinforced Concrete Frames through Gene Expression Programming [PDF]

Journal of Soft Computing in Civil Engineering
This study presents a novel approach for estimating the behavior factor of moment-resisting reinforced concrete (RC) frames using a gene expression programming (GEP) method, which involves designing and analyzing over three hundred RC frames.

Evaluation of the Seismic Retrofitting of Mainshock-Damaged Reinforced Concrete Frame Structure Using Steel Braces with Soft Steel Dampers

Applied Sciences, 2021
Most reinforced concrete (RC) frames would exhibit different degrees of damage after mainshock excitations, and these mainshock-damaged RC (MD-RC) frames are highly vulnerable to severe damage or even complete collapse under aftershock excitations.

An investigation on global ductility of strengthened RC frames

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2010
This paper presents a comparative study of global ductility of a reinforced concrete (RC) frame strengthened with external structural walls. The effect and suitability of the approaches used for evaluation of global yield displacement were examined. Then, using experimental and analytical methods, the variation of global ductility was investigated. In

STUDY OF THE BEHAVIOUR OF RC AND RCS FRAME

International Journal of Engineering Sciences & Research Technology, 2020
Composite Reinforced concrete-Steel (RCS) frames which consist of Reinforced Concrete (RC) columns and Steel (S) beams were represented to combine the advantages of pure RC and Steel frames. This system permits the primary steel beam to run continuous through the reinforced concrete column.
