Extension of Winkler’s solution to non-isothermal conditions for capturing the behaviour of plane geostructures subjected to thermal and mechanical actions

Lyesse Laloui, Qazim Llabjani, Alessandro Francesco Rotta Loria, Jacopo Zannin

Before this study, no analytical models had been made available for describing the behaviour of plane geostructures subjected to thermal and mechanical actions. This knowledge gap notably represented a limitation for investigations about the behaviour of s ...
