Abstract:

Three castellated beams were designed and tested. Based on the obtained experimental data,the me-chanical behavior,sectional stress distribution and loading capacity of the tested circular-hole and hexagon-hole castellated beams were analyzed.It is f0und that the loading capacity of the circular-hole castellated beam is greater than the hexagon-hole one.Moreover.the correctness of the reduced calculation iS verified by the comparison be-tween the theoretical values obtained by the reduced calculation and the tested values.Thus,the design methods of the two castellated beams are given.

Key words: castellated beam, reduced calculation, stress distribution
