Abstract
The practicing professionals mostly prefer to employ approximate models for the purpose of design of a structural domain. Model based on such method ignores a designer to evaluate the deformation pattern of the structure as a whole, as the actual 3D problems are over-simplified into 2D problems using line elements based on certain assumptions. Thus a designer handles a problem keeping him in darkness in these areas, rather adopts a conservative approach in view of quick and easy solution for the purpose at hand. Moreover reinforcement requirement remains on much higher side, thereby increasing hazards in detailing as well as construction site along with overall cost of the structure. Also in earlier days, sophisticated tools like various FEM packages were not also available commercially and easily in the market. Hence frames/structures were analyzed as grid structure/wire mesh. Although a wire mess gives some idea about the deformation pattern, but it’s unable to handle the complicated situations. It has been shown with the aid of present study of RC substitute frame that the values of bending stresses obtained thus are exceptionally on conservative side compared to the analysis output using FEM package, e.g. Abaqus. Here the behaviour of a substitute frame has been presented, following three different methods. Various results obtained have been compared to assess their potentiality and suitability in understanding true behaviour of such a system.
