Abstract
<p>Web perforations in corrugated web beams {CWBs) are essential in buildings for easy installation of services, etc. However, web openings lead to frequent instability and new failure modes compared to solid flat-web beams. A detailed nonlinear finite element analysis was performed on CWBs to examine their behavior under three-point loading for rectangular and triangular corrugated web profiles having hexagonal and octagonal openings. The numerical models were first verified against five documented flexural tests. Then a parametric study was performed on 16 CWB profiles having variations in dimensions, shapes of web openings and corrugation profiles. The results showed that a rectangular CWB with hexagonal openings was most efficient, having a maximum of about 24% reduced web thickness for a load-carrying capacity similar to that of tested flat-web specimens.</p>
