上一筆

A new methodology of beam with side plate is introduced to solve the problem regarding the workability of shear tab installation and beam-to-column force transfer mechanism. The beam end area is let uncovered of side plate and as a compensation of lower strength at beam end, a pair of cover plates are utilized to maintain the sufficiency of strength. A total of 6 specimens with 4 of them are the beam referring to the new developed beam were tested under reversal cyclic loading. The result shows that the new developed beam possess a good performance with enough ductility. However, the welding scheme and the overlapping length of cover plate should be designed properly to avoid the undesired of premature failure. A finite element (FE) model was then established and validated using the test result. The model is able to simulate the behavior of beam reasonably well with enough conservatism. Based on the verified FE model, the parametric study was conducted to establish the design formula for estimating the required length of side plate. Finally, the overall design guideline for developed method of beam was proposed.
