| Abstract: | Firstly, using the piecewise continuum technique for the structures,the coupled differential equations of horizontal vibration for the tall building frame-shear wall-thin walled cores skewly combined structures with stepped parameters and considering the effects of vertical loads have been derived. Secondly, using the Ordinary Differential Equation Solver, which is a program developed for solving various ODE problems including eigen value problems, the vibrational frequencies and vibrational modes have been obtained. The effects of vertical loads on horizontal vibration have been discussed. |
