Abstract: 

Accurate analysis of pierced shear walls by FEM needs many small elements in the domain of the structures because of openings existence. On the contrary, by modeling this structure with BEM, it is only necessary to discretize the boundaries which are less than the domain.
In this paper, DRM/BEM is used for calculation of natural frequencies of shear walls (especially pierced shear walls). Through this application, several radial basis functions (RBF) are considered. Then an RBF is proposed which has more accuracy in finding natural frequencies. The accuracy of the results are compared with solutions obtained based on FEM as bench marks. In conclusion, by parametric studies some wrathful points are proposed.
