【 摘 要 】

The paper presents a study on the behaviour of corrugated web steel beams with and without web openings. Examined steel beams consist of two flanges and a thin triangularly corrugated web, connected by automatic welding. In the literature, the web opening problem in steel beams was dealt with mostly for steel beams with plane webs and research of the effect from opening in a corrugated web was found out to be very limited. A finite element analysis in ABAQUS software was carried out to investigate the effect of openings in corrugated web. A number of beams FE models comprise of web openings with different sizes and positions were developed. The effect on beam bending capacity of circular opening in corrugated web is studied for various openings positions and sizes also as corrugation density. The stress concentration factors are obtained near the circular opening in cases of its location in zone of pure bending and in zone of transverse bending of the beam. Recommendations are given for practical design of corrugated web beams weakened by circular openings.
