【文章內(nèi)容簡介】 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 post and frame pillar , shearing force being designed being worth taking 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 them , first order takes , the two stage takes , gradethree takes , 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 secretly schemes against , the shearing force enhances a modulus being , the two stage is . 2) Shear formula The continuous beam of armored concrete and the cantilever beam are born the weight of at home and abroad under low repeated cycle load effect by the scissors the force experiment indicates the main cause pooling efforts and reducing even if tendon dowel force lessening is that the beam is born the weight of a force by the scissors, concrete scissors pressure area lessening shearing an intensity, tilted rift room aggregate bite. Scissors bear the weight of a norm to the concrete accepting descending strenuously being 60% be not antiknock, the reinforced bar item does not reduce. By the same token, the experiment indicates to insisting to intimidate post with that the force is born the weight of by the scissors, loading makes post the force be born the weight of by the scissors reducing 10% ~ again and again 30%, the item arouses , adopts practice identical with the beam mainly from the concrete. The experiment is indicated to shearing force wall, whose repeated loading breaks the subtraction modulus up than monotony increases be loaded with force lessening is born the weight of by the scissors 15% ~ 20%, adopts to be not that seismic resistance is born the weight of by the scissors energy times 39。s. Two parts accept the pressure pole strenuously tilted from the concrete is born the weight of by the scissors and horizontal stirrup of beam column node seismic resistance cutting the expert who bears the weight of force position , is connected with have given a relevance out formula. Tilted for preventing the beam , post , pany beam , shearing force wall , node from happening pressure is destroyed, we have stipulated upper limits force upper limit to be born the weight of by the scissors , have stipulated to match hoop rate’s namely to accepting scissors cross section. Reaction analysis indicates strong weak curved scissors requests。 all above measure satisfies basically by mistake elasticity driving force. The plasticity rotates because of antiknock grade of two stage beam column under big earthquakes still very big , suggest that the shearing force enhances a modulus is bigger than having there is difference between one step unsuitably in connection with the expert, to the beam choose is fairly good , ought to take ~ to post . It39。s the rationality taking value remains to be improved and perfected in going a step further. Require that explanatory being , the beam column node accept a force very plicated , need to ensure that beam column reinforced bar reliability in the node is anchoring , hold occurrence bending resistance at the same time in the beam column destroying front, shearing happened in the node destroy, whose essence should belong to strong weak curved scissors categories. The node carries out adjustment on one, two steps of antiknock grades shearing force and, only, the person enhances a modulus be are minor than post, ratio post also holds structure measure a little weak. As a result , more strong node “statement, is not worth it encourage. 3) Structure measure Structure measure is a beam, post, the shearing force wall plasticity cuts the guarantee that area asks to reac
