Abstract |
In this paper, the dynamic behaviour of coupled shear wall-frame systems is analyzed. The governing equations of the wall-frame systems with outrigger truss are formulated through the continuum approach and the whole structure is idealized as a shear-flexural cantilever with rotational spring. The effect of shear deformation and flexural deformation of the wall-frame and outrigger trusses are considered and incorporated in the formulation of the governing equations. transient response of the wall-frame structures with and without outriggers are compared by using finite element analysis incorporated with Newmark- method. Numerical results are obtained and compared with the finite element package MIDAS. The proposed method is found to be simple and efficient, provides reasonably accurate results in early design stage of tall building structures. |
