1) The document analyzes the behavior of a castellated beam with sinusoidal web openings using both Abaqus software modeling and experimental testing.
2) A castellated beam was modeled in Abaqus and subjected to a two-point loading test, similar to experimental testing. Deflections from the software and experiment were compared and found to have negligible difference.
3) Experimentally, a castellated beam was fabricated from an I-beam using a profile cutting machine. A two-point loading test setup was used to apply loads and measure deflection. Results matched closely with the Abaqus software analysis.
