A dynamic continuum plate model of a multi-story building is proposed in the form cantilevered orthotropic plate, developed framework Timoshenko’s theory plates, which describes seismic vibrations buildings. Formulas are given for determining reduced moduli elasticity, shear, and density building. Transverse natural forced oscillations nine-story under nine-point impacts considered. Numerical r...

A new approach for analyzing cracked problems in 2D orthotropic materials using the well-known element free Galerkin method and orthotropic enrichment functions is proposed. The element free Galerkin method is a meshfree method which enables discontinuous problems to be modeled efficiently. In this study, element free Galerkin is extrinsically enriched by the recently developed crack-tip orthot...
