Design of Openings and Static and Vibrational Analysis of RCC Cellular Beam
Abstract: In concrete arena, RCC cellular beams have less weight compared to solid beams which in turn reduce the weight of columns and footings. All real physical structures, when subjected to loads or displacements, behave dynamically. In this study, we have performed the static analysis and vibration analysis of a three-dimensional reinforced cement concrete cellular beam. The nodal displacements have been found and the stresses are determined. The principal stresses are …
