Modelling of inhomogeneous shell elements deformation under static and dynamic actions

Abstract

A mathematical model is proposed to study the influence of the characteristics of shock-absorbing elements on the stress–strain state of reinforced concrete shells with cutouts under the action of the vertical component of a seismic wave. A practical criterion is formulated for determining the optimal values of the parameters of viscoelastic shock-absorbing elements, based on a comparison of the amplitude–frequency characteristics of a seismic wave and a shock-absorbed foundation slab in the cases of periodic and limiting aperiodic motion.
