Abstract

Dynamic soil-structure interaction effects on coupled flexural-torsional vibrations of thin-walled cores of high-rise buildings are studied. A frequency- domain boundary element method is employed for the half-space representing the soil. A refined model, taking the shear strains due to non-uniform bending and torsion into account, is adopted for the structure. 1 Introduction Reinforced-concrete shear cores represent a widely used structural solution in the earthquake-resistant design of buildings or in the strengthening of damaged masonry structures. These shear cores are typically constituted by staircases, lift-wells or specially designed members characterized by a numbe
