框架结构薄弱层的验算和控制(国外英文资料) The examination and control of the weak layer of frame structure (the frame shear structure should remove the shear wall and then be flexible.) A control meaning: Avoid the easy occurrence of weak layer, if unavoidable take corresponding measures to strengthen B standard provisions High gauge 4.4.2, 5.1.14 rule, seismic design of high-rise building structure, the lateral stiffness is less than 70% of its on a layer of floor or less than 80% of its three layers in the lateral stiffness are average, or a floor vertical discontinuous component to resist lateral force, the weak layer standard values corresponding to the seismic action of seismic shear coefficient with the increasing of should be multiplied by 1.15. Gauge fan regulation: high gauge 4.4.3 and 5.1.14 rule, A level between the height of the high-rise building floor layer upon layer shear bearing capacity of structures to resist lateral force should not be less than its 80% of A layer of shear bearing capacity, should not be less than its on A layer of shear bearing capacity of 65%; The shear bearing capacity of the lateral force structure of the upper floors of the high-rise buildings should not be less than 75% of the shear capacity of the upper layer. Aseismic design of high-rise building structure, building structure layer upon layer between the bearing capacity of the structure to resist lateral force is less than 80%, its standard with weak layer corresponding to the seismic action in earthquake shear should increase multiplied by the coefficient of 1.15. C method and program implementation Weak layer method: judge by layer stiffness ratio Weak layer method two: according to the floor bearing capacity ratio is judged Weak layer method 3: the displacement Angle between the layer elastic-plastic layer is judged is judged by the stiffness of the layer Specification is required to clear the stiffness of the structure of the layer, weak in determining if a floor layer, the calculati
