The deformation properties of concrete arch dams are affected by the synergistic effects multiple factors, featuring strong, multidimensional spatialtemporal evolution and distribution characteristics. This paper proposes a zoned safety monitoring model for dam based on similarity optimization to evaluate state structures. First, clustering points at different locations an was performed using p...

Contact problems are among the most difficult issues in mathematics and of crucial practical importance engineering applications. This paper presents a scaled boundary finite-element method with B-differentiable equations for 3D frictional contact small deformation elastostatics. Only boundaries system discretized into surface elements by method. The dimension is reduced one. conditions formula...

This paper presents a study of two-pin arches constant cross-section that are moment-less under statistically prevalent (permanent) load. The defined by analytical form-finding previously reported in Lewis (2016) [1]. work provides guidance regarding the solution process, and expressions for reactions axial forces. New results include derivation arch length, method finding co-ordinates individu...
