【正文】 引導(dǎo)結(jié)構(gòu)形成 “ 梁鉸機(jī)構(gòu) ” 或者 “ 梁柱鉸機(jī)構(gòu) ” ；通過“ 強(qiáng)剪弱彎 ” 避免結(jié)構(gòu)在達(dá)到預(yù)計(jì)延性能力前發(fā)生剪切破壞；通過必要構(gòu)造措施使可能形成塑性鉸的部位具有必要的塑性轉(zhuǎn)動能力 和耗能能力。 由于建筑抗震設(shè)計(jì)的復(fù)雜性，在實(shí)際工程中抗震概念設(shè)計(jì)就顯得尤為重要。 Framed structure is to pass the design plan calculating and ing realize structure measure the ability running after beam hinge organization mainly thereby, realize the small earth—quake shocks does not but constructs in the dirty trick, big earthquakes do not fall three standards toen fortifying target39。 Nature is growing with axis pressure than enhancing , consuming an energy, but the gentility sudden drop, moreover the stirrup diminishes to the gentility help. Readjust oneself to a certain extent to adopt the pillar, main guarantee 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 reach the plasticity that reality needs turning ability and consuming ability. Its strong with strong weak scissors turn , weak post beam correlates, a architectural denasality of guarantee.”Strong weak scissors turn is a prerequisite for ensuring that the plasticity hinge turns an ability and consumes an ability。s by to enhance a modulus. Prop up antiknock wall structure to part frame, bottomend , whose curved bination regulation design value respond to one, two steps of frame pillars post upper end and bottom post take advantage of that poses in reply in order to enhancing a modulus respectively. All above strong weak post beam” adjustment measure, reaction analysis indicates , big satisfied fundamental earthquakes demand no upside down course nonlinearity driving force. Reinforced 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。s。 Avoid structure by strong weak scissors turn before reach estimate that shearing happened in the denasality in the ability front destroy。The frame structure anti earthquake concept design The disaster has an earthquake dashing forward sending out nature, may forecast nature very low so far, bring about loss for human society is that the natural disaster of all kinds is hit by one of the gravest disaster gravely. In the light of now
