【文章內(nèi)容簡介】 d bar spending area, the beam in 7 is controlled from gravity load, the post reinforced bar matches’ tendon rates basically from the minimum under the control of. Have enhanced post Liana Xiang all round resisting the curved ability. At the same time, 7 degree of area exactly curved regulation plasticity hinge appears on disaster very much, plays arrive at advantageous role to fighting against big earthquakes. In 9 degree of area, adopt reality to match reinforced bar area and material bending regulation within intensity standard value calculation post, structural beam reinforced bar enhancing same lead to enhancing bending regulation within post designing value, under importing in many waves, the beam holds the plasticity hinge rotating developing greatly, more sufficient, post holds the plasticity hinge developing insufficiency, rotate less. Design demand with the beam. Reaction and 9 degree are about the same to 8 degree of area , whose big earthquake displacement , that post holds the plasticity hinge is bigger than rotating 9 degree much but, the beam holds the plasticity hinge appearing sufficient but rotate small, as a result strong weak post beam effect is not obvious , curved regulation enhances a modulus ought to take , this waits for improving and perfecting going a step further when the grade suggesting that 8 degree of two stage is antiknock in connection with the expert. 2, Strong shear weak curved Strong weak scissors turn” is that the plasticity cuts cross section for guarantee on reach anticipate that shearing happened in the mistake elasticdeformation prior to destroy. As far as mon structure be concerned, main behaviors holds in the beam, post holds, the shearing force wall bottom reinforces area , shearing force wall entrance to a cave pany beam tools , beam column node core area. Show mainly with being not that seismic resistance is pared with each other, strengthening measure in improving the effect shearing force。 Aspect adjusting a shear bearing the weight of two forces. 1) effect shearing force One, two, threelevel frame beam and antiknock wall middle stride over high ratio greater than pany beam, shearing force design value among them , first order choose , two stage choose , threelevel choose , first order framed structure and 9 Due Shan respond to coincidence. Coincidence one, two, three steps of frame taking post and frame pillar , shearing force being designed being worth among them, one step , taking , three steps of take , onelevel framed structure and 9 Due Shank two steps responding to. One, two, three steps of antiknock walls bottom reinforces location the shearing force designs that value is among takes , themgradethree takes , , first order takes , the two stage 9 Dud Shank respond to coincidence. The node core area seismic resistance the beam column node , one, two steps of antiknock grades are carried out is born the weight of force checking calculation by the scissors , should accord with antiknock structure measure about 3 step, correct 9 degree of fortify and onelevel antiknock grade framed structure, think to the beam end the plasticity hinge already appears , the node shearing force holds reality pletely from the beam knuckling under curved regulation decision , hold reality according to the beam matching reinforced bar covering an area of the growing modulus that intensity standard value calculation, takes advantage of that at the same time with with material. Other first order holds curved regulation according to the beam designing that value secr
