Abstract –High-strength steel are better than normal steels.
Commonly these are castoff for the construction of bridges, offshore constructions etc. In this project a (FEM) was developed for H-section in high-strength steel beams. Mainly used to calculate the presentation of H sections beams by changing the diameter of holes such as 67.5 mm, 74.25mm, 81.675mm and 89.84mm. To examine the presentation of crippling loading on H-section steel beams having changing number of circular opening. The result acquired that, the most apct diameter of the hole is about 89.84mm, also the four number of holes give maximum result.

The diameter of the holes are changed to 67.5 mm diameter, 74.25mm, diameter, 81.675mmdiameter, 89.8425mm diameter. That means a 10% increase in hole section.
Keywords: FEA, Web opening, H-section, crippling loading 1. INTRODUCTION 1.1 General Background The use of steel have lately enhanced many architectural presentations such as bridges skyscrapers and offshore constructions. Related near normal strength steel, high strength steel have progressive strength and better stiffness. Which can reduce the weight of structures assembly it more proper for large intergalactic assemblies and long-span bridges.
