结构调整系数在规范中的体现(国外英文资料) The structural adjustment of Chinas regulations (2011-06-01 12:28:05) The structure of the Chinese standard adjusts the author: zhu xin Is set to code for seismic design of buildings strong column weak beam , strong shear weak bending, strong node strong weak anchoring components design idea, according to the structure type, seismic fortification intensity and building height decision structure seismic grade; Then the internal force of structural component design is adjusted according to the earthquake resistance level. In the specification, the structure aseismatic rating is divided into four levels (one, two, three and four). The high-level procedures have added some additional regulations based on the characteristics of the high-rise buildings, adding a special level. All the seismic grade of beam and column on the combination of internal force design values for different coefficient of adjustment, is used to limit to flame under the plastic hinge region area, avoid or reduce the brittle shear failure before bending failure delay the formation of plastic hinges, strengthen column root control collapsed, do small earthquakes not bad, the shock repairable, flame to fail. The classification of internal forces adjustment The structure of high-rise buildings under load is calculated by structural analysis, and the internal force standard value of each component is obtained, and the design value is obtained through various modification and adjustment. Internal adjustment and adjustment are generally divided into two categories. The first category belong to the whole structural internal force adjustment, mainly including: floor minimum earthquake force limit control, weak layer shear amplification, frame shear structure framework in part by the earthquake in the adjustment and transformation layer (box) of the total shear box pillar earthquake shear force adjustment, etc. The characteristics of this kind of adjustment is that, in does not meet cer
