Abstract: A nonlinear stiffness matrix based computer program is used to investigate the stability of elastic space structures whose likely failure modes are determined by examining the tangent stiffness matrix of the structure near ...

Abstract: A numerical and experimental study of the collapse and postcollapse behavior of shallow lattice domes is presented. The numerical analysis is based on an updated Lagrangian, materially and geometrically nonlinear, ...

Abstract: This paper presents an advanced nonlinear finite-element (FE) program developed for the analysis of general composite structures of steel and reinforced concrete, including composite space trusses. The elements used to ...
