This paper presents the structural design data for preforated
composite beams with circular web opening. From this study,
we could find out the following conclusion;
1. Perforated composite beams with high moment - shear ratio were
failed by stress concentration in the vicinity of bottom tee and
high moment.
2. The initial stiffness was not concerned with the ratio of M/V.
3. The ultimate strength, fracture pattern was considerably
concerned with the ratio of M/V. Especially fracture shape of
NWC60 specimen was similar to steel beam.
