Fragility Curves for Reinforced Concrete Frames with Lap-Spliced Columns
Placing column lap-splice in the locations of possible nonlinear deformation may adversely affect the structures response to strong ground motions. Localization of damage in splice zone may change the structural response and prevent the load redistribution and development of a uniform pattern of nonlinear excursions among the various members. Validated by existing laboratory experiments, this s...
متن کاملRehabilitation of Reinforced Concrete Columns
In recent years, rehabilitation has been the subject of extensive research due to increased spending on building work and repair of built works. In all cases, it is absolutely essential to carry out methods of strengthening or repair of structural elements, and that following an inspection analysis and methodology of a correct diagnosis. The reinforced concrete columns are important elements in...
متن کاملA Numerical Approach for the Seismic Analysis of Reinforced Concrete Structures Environmentally Damaged and Cable-strengthened
The paper deals with a numerical analusis for the seismic response of reinforced concrete structures containing cable elements. The cable behaviour is considered as nonconvex and nonmonotone one and is described by generalized subdifferential relations including loosening, elastoplastic fracturing etc. effects. The problem is treated incrementally by double discretization: in space by finite el...
متن کاملCyclic and Monotonic Behavior of Strengthened and Unstrengthened Square Reinforced Concrete Columns
The use of composite materials is an effective technique to enhance the capacity of reinforced concrete columns subjected to the seismic loading due to their high tensile strength. In this paper, numerical models are developed in order to predict the experimental behavior of square reinforced concrete columns strengthened by glass fiber reinforced polymer and steel bars and unstrengthened colum...
متن کاملNumerical Simulation of Debonding Failure of Reinforced Concrete Beams Strengthened with Externally Bonded Frp
As the life age of the existing structures are required to meet the changing demands on civil infrastructures. So strengthening and retrofitting are required. Recently many techniques to strengthen the reinforced concrete beams in flexural by using fiber reinforced polymer (FRP) had appeared. The most famous technique among them is strengthening the (RC) beams with externally bonded FRP sheet t...
