Membrane action in shells
WebA general finite element method of analysis is developed to analyze reinforced concrete shells of general form and slabs of arbitrary geometry under dead load and monotonically increasing live loads. The method can be used to trace the load-deformation response and crack propagation through the elastic, inelastic, and ultimate ranges.
