Part of: Finite Element Analysis of Reinforced Concrete Structures II:

Abstract: Generic Problems are basic problems in structural mechanics that recur frequently, have been investigated experimentally and involve the behavior of elements or components found in many complex structures. The present Chapter considers panels, shear walls, shallow and deep beams, beam-column connections and Mode I crack propagation in unreinforced members. It is found that significant progress has been made in analyzing panels and shear walls where the smeared crack approach has been adopted to incorporate rotating cracks and multiple, non-orthogonal cracks. Discrete and plastic fracturing approaches to modeling the behavior of wall elements are discussed. The possible application of this technology to beam-column joints is noted. The application of fracture mechanics concepts to finite elements analysis of notched beams and he implications for improving models of other elements, such as panels, is also noted.
