【 摘 要 】

Principal features of the non-smooth contact dynamics method, which served as basis for the LMGC90 software formulation, are presented in the paper. The objective of the paper is to present creation of a discrete model using the LMGC90 software. The discrete dome model of the St. Jacob cathedral in Šibenik was created, and dynamic behaviour of the dome was checked by time-history analysis. The results point to a highly nonlinear behaviour of the dome, which would be difficult to detect with the finite element method. The results also reveal critical points, i.e. the maximum displacement and contact force points along the dome.
