Triangular web profile (TriWP) steel section with various combinations of perforation shapes, sizes and layouts of perforation are investigated under shear loading condition. The aim of this study is to determine the structural efficiency based on the ratio of buckling load, Pb to the self-weight of the model. For this purpose, the specimen with three different perforation size between 0.4D to 0.6D, five perforation shapes i.e. circle, square, hexagon, diamond and octagon and three different layouts of perforation, which are Layout 1, Layout 2 and Layout 3 are analyzedby using LUSAS software. It involves two stages of analysis which are Stage 1 and Stage 2. In Stage 1, the most efficient perforation shape, size and layout of perforation is determined based on the highest structural efficiency value. From the result obtained, the TriWP with perforation of diamond in shape and 0.4D in size arranged in Layout 3 shows the highest structural efficiency value i.e. 204.75 produced from the highest buckling load. It shows the lowest percentage difference of efficiency compared to that of TriWP without perforation i.e. 16.39%. It leads to the most efficient perforation shape, size and layout. Then this type of model is analyzed for different section properties and span length to observe the effect performance and its structural behavior under Stage 2. It observed that, shear buckling capacity increase proportional to the web thickness. Meanwhile, when the span length is increase from1 m to 5 m, the shear buckling capacity reduce.
