Crack Failure Analysis of Scaffolding Frame Intersection using ADINA

Abstract

This paper describes the analysis of scaffold frame intersection joint crack. Independent scaffolding type is selected and analyzed for the cracks and deformations. The modelling of the structure is done with the Solid works software and the rendered model was imported to ADINA structures software. All the dimensions for the scaffold design were followed as specified in the standard codes BS4945. Live loads of 2kN/sq.m were taken. The post processing is executed and the results were generated. The results show that maximum bending moment 11.94N-m is at intersection joints particularly at joints. The minimum bending moment -13.44N–m has occurred below the junction the effective stress calculated around the junction of the scaffold is 3.493N/mm2 and the deformation of the scaffolding frame is at intersection joints and the cracks are formed. Visualizing the crack by using ADINA may be the best way to estimate the deformation modes and crack. This will definitely be useful for the remedial measures to prevent cracks in a scaffold structure.
