Abstract
A numerical investigation on built-up closed cold-formed steel beam section with web opening was undertaken using Finite Element Analysis. The most accurate approach to understand the behaviour of cold-formed steel sections with the presence of perforations is by laboratory testing. However, the laboratory testing is expensive and take a long time. The development of numerical analysis and modelling using Finite Element software is another alternative that can eliminate the expensiveness and time taken by laboratory testing. Thus, Finite Element Method was used in this study to model and analyse the built-up closed cold-formed steel beam section with web opening. The aim of this study are to determine the maximum stress, maximum strain, and maximum buckling load of built-up closed cold-formed steel beam with web opening. Besides, the buckling modes of built-up closed cold-formed steel beam due to various shapes and numbers of web opening was investigated in this study. For this purpose, finite element model was developed using LUSAS Modeller 14.0 which having circular and square shapes of opening. Each shape has five specimens which one of them is beam without perforation and the rest having various numbers of web opening. The beam length used for all specimens is 1600 mm. Pinned and roller ended support was assigned to validate the Finite Element Analysis. Each model was subjected to two points loading. The type of meshing used was QSL8 for all specimen. The simulation involved in this study are linear analysis and linear buckling analysis. The results obtained from finite element analysis includes deformed shapes, maximum stress, maximum strain, buckling behaviour, and maximum buckling load of built-up closed section beam. From the results, it is shown that the strength of built-up closed cold-formed steel beam was greatly varied with the perforation parameters. The built-up closed section beam without web opening was stronger in strength but had failure in local buckling. Meanwhile, for the built-up closed section beam with web opening, the strength was reduced by the perforations. However, this gives many advantages to them. The presence of perforation in beam are important to accommodate plumbing, electrical, and heating services to the walls and ceilings of the buildings, and perforations can stop the local buckling from occur in the beam. In conclusion, the built-up closed cold-formed steel beam section with web opening can be used in construction industry, but they need to be designed with the best performance.
