The Limit Displacement Angle. The limit displacement angle [R.sub.u] is defined as the ultimate deformation capacity of the wall, and the H value of the wall plus half depth of the top beam, that is, 2590 mm; it can be calculated from Equation (3).
Table 5 shows that the structural column has an ultimate ductility coefficient and an ultimate displacement angle, which indicates that the structural column has a certain influence on the ductility of the wall.
In order to avoid the influence of mining, coal pillar for lateral roof roadway was designed via the displacement angle of rock strata.
When the vertical distance between the roadway and the coal seam is L, the width of coal pillar designed according to the traditional displacement angle of rock strata is a.
The 1 translational cycle T1=4.71s (Y direction translation), the cycle than Tt/T1=0.76; structure in X and y to the maximum displacement and the ratio of average displacement maximum value of 1.13; maximum story drift angle is 1/1105 in the 23rd floor, specification of frame core tube is less than the interlayer displacement angle maximum 1 / 800; structure the stiffness ratio of 1.13, on the twelfth floor of the structure, minimum floor shear bearing capacity of 0.86, vertical structure rules, there is no weak layer.
By comparing Figure 5 (c) and elastic time history analysis and response spectrum method calculated interlayer displacement angle did not exceed the allowable value of drift angle of 1 / 800, can meet the requirements of specification and transform of seismic wave interlayer displacement angle value, the overall to response spectrum curve near.
According to the results, in above connections no resistance loss will be observed until the relative displacement angle of story equals to 0.04 radians.
When the usual assumption that the motion be kept small is released, the restoring force becomes proportional to the sine of the displacement angle (rather than to the displacement angle itself) and the pendulum becomes a non-linear system.
Thus, as shown in Figure 1, it can be considered that the rotation at the ends of CB chords is the same as the interstorey displacement angle of the shear walls.
It is assumed that the shear force at level i is [V.sub.i]; the storey drift and interstorey displacement angle are, respectively, [[DELTA].sub.i] and [[alpha].sub.i]; the storey height, CB depth, and segment length of the CB are [h.sub.i], d, and l, respectively.
The efficiency ([eta]) has been experimentally found for different receiver displacement angles ([theta]) and the results are shown in Table 2.
According to Venturini algorithm there are two solutions, one is the input and output displacement angles which are same ie [[phi].sub.i] = [[phi].sub.0] and second is the input and output displacement angles which are dissimilar or reversed ie [[phi].sub.i] = -[[phi].sub.0].
