A macro joint element for nonlinear arch dam analysis
Abstract
The family of isoparametric joint elements with zero thickness is reviewed as standing between thin-layer and spring-box models. A threedimensional version, compatible with conventional 20 -node solid elements, has been refined to capture in coarse discretization the full range of joint nonlinearity in arch dams and their abutment rock in a seismic event. This paper concentrates on the opening/closing performance and discusses remedies to the notorious oscillatory tendency in the family.
