The Research On The Seismic Behavior Of R.C Space Joints Strengthened By Carbon Fiber Reinforced Polymer

Framed structure is one kind of structure form,that most probably is to be a universally recognized in application of our country.That the frame node is getting the effect linking a beam and a column,transferring and assigning the internal force, deformation,guarantee structure globality between harmonizing the structure component in framed structure,is important framed structure location.With the advancement of society and development of the economy,demand of various building and the structure user to whose project mass and usage function is more and more high. Besides,our country has very big batch of building to approach a service life already,in destroying border.The strengthening method's therefore to the engineering is extremely urgent.Carbon Fiber Reinforced Polymer(CFRP) is one kind of the new materials having the fine Mechanics function,have tensile strength height,resistant to corrosion,resist to become fagged,weight merit such as light,being under construction conveniently, the application consolidating aspect in reinforced concrete structure are more and more broad.As far as the node consolidates,great majority are aimed at the flat surface node problem only,the go into to space node is less.Be allotted several kinds the following according to location diversity got along by node:Top storey edge post node;The top storey is hit by the post node;Top storey corner post node;Edge post node;Be hit by the post node;Corner post node.The main body of a book will take framed structure middle level edge node as main marriage partner,the seismic resistance function concentrating on reinforcing the day after tomorrow to frame space node studies.Accept force mechanism and reinforce way rationally by the fact that the Carbon Fiber Reinforced Polymer testing result analysis,revealing spreads the node consolidating frame space's.The writer has designed and making five beam column space middle level edges node examination,the core area consolidating the form and the node with Carbon Fiber Reinforced Polymer matches for the main body of a book for hoop rates testing a parameter mainly.One among them is that not strengthening suiting competes a piece, the others four examination adopt different Carbon Fiber Reinforced Polymer to paste strengthening method but then.The entire proceeding carrying out by testing,observing diversity to consolidate examination from the rift until destructive,comparative analysis it's the aspect difference such as destroying form,bearing the weight of the force,stiffness,to explore out the best aseismatic strengthening method of space node.
