刚度比位移比周期比详解（Stiffness ratio, displacement ratio, cycle ratio）

刚度比位移比周期比详解（Stiffness ratio, displacement ratio, cycle ratio） PKPM stiffness ratio, displacement ratio, cycle ratio, detailed explanation, 2008, 05, Friday, 23, 10:11, cycle ratio Specification: 4.3.5 provides high compliance, the first cycle of Tt and translational torsion structure composed of the first cycle of T1 ratio, a high-rise building height should not exceed 0.9; B height of high-rise buildings, high-rise buildings and mixed structure of complex high-rise building should not be greater than 0.85. For regular regular single tower structures, the following check cycle ratio: 1) according to the translation coefficient of each mode is greater than 0.5, or the torsion coefficient is larger than 0.5, to distinguish each mode is torsional and horizontal vibration type 2) torsional mode the longest cycle is usually corresponding to the first torsion cycle Tt, translation mode corresponding to the longest period of the first cycle of T1 is flat 3) space structure vibration control diagram, the first torsion / translational cycle can cause the vibration of the whole, if not the first is only partial vibration, torsion / translational cycle. On a long cycle. 4) to investigate whether the ratio of the base shear ratio in the first translation period is the maximum 5) calculate the Tt/T1 to see if it exceeds 0.9 (0.85) What does the cycle ratio control? As the control displacement ratio, cycle ratio is focus on the control of lateral stiffness and torsional stiffness of a relative relationship between, not its absolute size, its purpose is to make the layout of the lateral force resisting members more effectively and make the structure more reasonable, not to appear too large (relative to lateral) the torsion effect. In a word, the cycle ratio control is not required for the structure to be strong enough, but rather the rationality of the structural layout of the structure Cycle ratio does not meet the requirements, how to adjust? Once the cycle occurs than the situa
