Retrofitting of Beam-Column Joint Using CFRP and Steel Plate
─This paper presents the retrofitting of beam-column joint using CFRP (Carbon Fiber Reinforced Polymer) and steel plate. This specimen was tested until failure up to 1.0% drift. This joint suffered severe damages and diagonal cracks at upper crack at upper column before retrofitted. CFRP were wrapped at corbel, bottom and top of the column. Steel plates with bonding were attached to the two bea...
متن کاملPerformance of the Modified Precast Beam to Column Connection Placed on a Concrete Corbel
Precast concrete structures in Iran are generally designed as continuous columns with hinged beams, thereby making them simple frames. In this system in site show walls in two directions of buildings guaranteed lateral resisting system. However, in order to obtain a seismic resisting frame, the connection between beam and column should be moment resisting and ductile, allowing the formation of ...
متن کاملperformance of exterior precast concrete beam-column dowel connections under cyclic loading
the present study focuses on the performance of precast concrete beam-column dowel connections subjected to cyclic loading by conducting experiments. in this study, one-third scale model of two types of precast and a monolithic beam-column connection were cast and tested under reverse cyclic loading. the precast connections considered for this study is a beam-column connection where beam is con...
متن کاملNonlinear Earthquake Analysis of Reinforced Concrete Frames with Fiber and Bernoulli-Euler Beam-Column Element
A beam-column element based on the Euler-Bernoulli beam theory is researched for nonlinear dynamic analysis of reinforced concrete (RC) structural element. Stiffness matrix of this element is obtained by using rigidity method. A solution technique that included nonlinear dynamic substructure procedure is developed for dynamic analyses of RC frames. A predicted-corrected form of the Bossak-α met...
متن کاملEvaluation of Column-Tree Moment Resisting Connection with End Plates and Haunched Beam (RESEARCH NOTE)
The column-tree constructional schemes allows for a reliable and convenient erection of moment resisting steel frames. Strengthening of column-tree connection with a haunch part can significantly improve seismic behavior of whole system. In the current study behavior of column-tree connections with haunched beams and end plate splices have been investigated. Special attention was paid for evalu...
