1、A study of the method for limiting the story stiffness ratio of RC frame structures

2、Study on reasonable line stiffness ratio of framework beam and column based on optimization theory

3、These are prestress in cables, sag of cables, rise of arches, the vertical flexible stiffness of arches and the axial stiffness ratio between the cable and the arch.

4、The coefficient of lateral pressure varies with the stiffness ratio between lining and ground, it being larger than the coefficient at rest.

5、Other test parameters include the level of axial load in the CFST column, the load level in the RC beam and the beam-column stiffness ratio.

6、Case study shows that rational determination of the friction coefficient and the stiffness ratio of these two kinds of bearing is helpful to obtain good effect of vibration isolation.

7、Furthermore, it was shown that load-displacement of pile groups and load distribution on pile top were affected by properties of soil and stiffness ratio of piles to soil, and by length, diameter, spacing, and number of piles.
