This work employs three numerical modeling approaches to represent different failure modes observed in an RC frame collapse shake table experiment. The first model, called FAM Model in this paper, consists of linear beam-column elements with nonlinear zero-length hinges at two ends of each column. The second model, called Fiber-Section Model, uses nonlinear beam-column elements with fiber sections to simulate column flexural behavior and its failure. The third model, called Limit-State Model, extends the Fiber-Section Model by adding a nonlinear spring between each column top and the strong beam to simulate the shear limit-state failure. The springs at the top of the column use a limit-state shear failure model. The details of the above modeling approaches for the RC frame are introduced. This paper briefly summaries possible future study topics of the three models. |
