Abstract

Abstract: The paper deals with numerical research as to how material damping influences the load-bearing
structures in dynamic loads. Certain technique is suggested for modelling behaviour of structure in time history
analysis with account of material damping. A set of motion equations is solved according to Newmark method as
matrix. Physical meaning of material damping is described. The authors suggest the technique for account of
different materials in parts of structure. The following example is provided: analysis of structure together with
soil and with account of earthquake loads. Analysis results are compared (with and without account of material
damping). Significant influence of damping on the stress-strain state of the structure is confirmed.
