The main indexes used to control structural integrity are: cycle ratio, displacement ratio, stiffness ratio, ratio of shear capacity between layers, ratio of stiffness to weight, shear weight ratio, etc..
(1) the cycle ratio is an important index to control the torsion effect of structure. Its purpose is to make the plane arrangement of anti lateral ponents more effective and reasonable, so that the structure does not appear too large torsion. That is to say, the cycle is more reasonable than the requirement, but the structure is reasonable. Article of the high standard stipulates the requirements of the ratio of the first natural vibration period Tt and the first libration period T1 of the libration to the main torsion of the structure. If the cycle does not meet the specification requirements, indicating the structure torsion effect is obvious, designers need to increase the stiffness of the surrounding ponents, reduce the structure of ponents to the overall stiffness, increase the torsional stiffness of the structure.
Cycle design software usually does not directly give the ratio of the structure, need to design personnel according to the calculation value determined by the first cycle (cycle reverse translation). Following the introduction of practical calculation method of cycle ratio: 1) torsional period and translation period of judgment
