On the frame beam-column joint reinforcement
Reinforcement anchorage length of steel yield strength,
mulberry bags uk, concrete cylinder standard anti-28d, compressive strength of plant function, that is, = KJ_. 2) Chinese standard formula bar form factor a is given directly by the form factor table,
replica oakley sunglasses, a form only about wars and steel, other factors influence the length of the anchor, the correction factor for calculating the anchorage length of the re-revised; U.S. regulations formula coefficient K is given by the formula, namely: K = (3) (cb + ... Ktr) '/ db. 3) China specification when HRB335, HRB400,
true religion outlet, RRB400 diameter greater than 25Inln grade steel, its anchorage length should be multiplied by the correction factor of 1.1; U.S. regulations have reinforced the size factor,
herve leger sale, provided not more than 6 (diameter 19Inln) and deformation of steel wire = 0.8, not less than 7 (diameter 22nlln) steel = 1.0 4) China specification HRB335, HRB400, RRB400 level of epoxy-coated reinforcement,
tory burch outlet, the anchorage length should be multiplied by the correction factor 1.25; coated coefficient of U.S. regulations requiring protective layer of concrete not less than three times the thickness of the bar diameter or steel reinforcement spacing not less than 6 times the diameter of the epoxy-coated reinforcement = 1.5, Other epoxy-coated reinforcement: 1.2, not coated reinforcement = 1.0 (this time should be ≤ 1.7). 5) China to consider the specification of reinforced concrete construction in vulnerable disturbances, the anchor length should be multiplied by the correction factor of 1.1; the United States does not regulate this requirement. 6) China specification HRB335, HRB400, RRB400 grade steel in the anchorage zone of the concrete cover thickness greater than 3 times the diameter and reinforced with stirrups, its anchorage length can be multiplied by the correction factor 0.8; U.S. specification does not this requirement. 7) have reinforced the U.S. position coefficient specification to provide reinforcement for the top level = surface height; in CFRP under the binding area of plain concrete plus axillary nodes and core cross-section beam has a direct enhancing effect on the overall framework capacity increase is also very obvious. Beam-column joint application CFRP-concrete beam reinforcement plus axillary combination method, the end of the beam section height increased, the shear, bending along the carrying capacity also increases. Wrapped with carbon fiber ring to the role, constraints of the beam-column joint shear deformation, shear deformation of the core area of making a substantial reduction, the core area of the node increases the shear strength and stiffness. 2 Conclusion Currently, the project has been completed and put into use and acceptance. According to track and monitor display, the beam-column joints reinforced normal use and without any anomalies, showing that the program achieved the desired results.
