Lastly, by using the FORTRAN language, the thesis compiles the program of the stiffness optimization process of short-leg shear wall-corewall structure.
Because the ideal “rigid joint” and “hinged joint” are inexistent, the stiffness of any connection types is between ideal rigid joint and hinged joint.
The semiactive variable stiffness and damping control device outperforms the semiactive variable stiffness control as the result of the presence of auxiliary damping in this device.
That we use finite element analysis calculate to the strength and the rigidity of the bodywork structure.Thus the optimum fillet of the small underframe structure can be specified.
The shoulderbeam is a joint point between the upper and lower part of polystyle columns.Based on its mechanical analysis,the shoulderbeam is simplified to an elastic hinge with angle stiffness.
By observation and analysis of the test data, changing the plate steel endshield of motor into the disc iron one can improve the rigidness of endshield, and reduce the axial vibration of motor.
Therefore, when taking ground hardening measures, more consideration should be given to the use of materials with light self weight while meeting a certain stiffness.
In contrast, the proposed solution is more reasonable and accurate, by taking complex interactions between internal forces and stiffness reduction at circumferential joints into account.
Each circumferential joint is modeled as a shearing spring and a rotation spring, taking into account the stiffness reduction at the circumferential joint.
