✦ Synopsis

This paper presents a substructuring-frontal combined algorithm for the analysis of fully coupled heat, moisture and displacement problems in unsaturated soil. The method adopted for solving the assembled matrix equations has a signi®cant bearing on the computer storage requirement and execution time. Numerical examples are given to validate the proposed model.
