碩士 / 國立臺灣大學 / 土木工程學研究所 / 99 / This research presents the results of component tests and finite element analysis on the ultimate shear capacity of shear stud under the composite deck. All specimens were composed by a steel beam and two decks and connected with steel beam and deck by shear connectors. There were six push-out test specimens were experimented. From the results, it showed the failure modes of all specimens were caused by shear failure since the stud ultimate shear capacity under FRP deck lower 10 % than the AASHTO specifications (2004) stud control part AsFu. According to the experimental report, there were two obvious reasons; the mainly one was because of the mortar cell’s cracking and the other is due to bedding layer cracking. Using a larger stud diameter would have a larger ultimate shear capacity. However, using one or two studs in one row did not make any difference between stud ultimate shear capacities. Furthermore, this experiment was analysis via ABAQUS(2003).Firstly, the result of the simplified model completely met every condition of the analysis of cement mortar specimen; however we met a difficulty of the composite specimens owing to the cracking during experiment on ABAQUS. There is around 15 % error between the analysis and the test results. Followed, the analysis was examined by the full scale model; it reported the same between simplified model and full scale model. It means that the full scale model could be totally replaced by the simplified model in order to saving time. According to both the original design and results of this study, FRP deck in the open hole which is four times stud diameters could effectively protect the FRP deck by not being crushed. Moreover, this study recommended 100 mm of the shear stud spacing referred from EUROCODE-4(1997) to make sure that the shear capacity would not be affected the stud number in one row.
