Dynamic Analysis of Irregular Multistorey Shear Wall Buildings Using Continuous-Discrete Approach
The paper presents an analysis of coupled flexural-torsional vibrations of multi-storey shear wall buildings using continuous-discrete approach. A dynamic model with masses in the form of rigid floor slabs has been adopted. The mass matrix is generated exactly, according to real layout of walls, connecting beams and floor slabs. The flexibility matrix is generated on the basis of the solution of the governing differential equations for a three-dimensional continuous model. In order to verify the presented method, for the first example the free vibration analysis of non-planar, non-symmetrical coupled shear walls, previously analysed in the literature by SAP2000 program, has been chosen. In the second example, the possibility of seismic location of the multistorey building, designed originally in Poznań, stiffened by the asymmetrical system of coupled shear walls, was considered. The analysis, in which a continuous-discrete approach and the response spectrum technique were applied, was carried out by means of DAMB (Dynamic Analysis of Multistorey Buildings) program. The presented method is efficient and can be useful at the preliminary design stage when the solutions for a structure with many various geometrical and physical arrangements are required.
