Then a numerical analysis of the test structures is done using a fully coupled numerical finite element model. The break-up process of the structure is simulated. The failure modes of the simulated structure agree well with the experimental results. The effects of the size of the reinforcing bars and the detailing of connections among the rebars in the concrete on the throw velocity of the fragments are discussed.展开更多

Lance, the oldest of the Loud family children, is on film both flamboyant and effusive, but at the same time-through judicious editing--an asexual creature with no romantic or sexual relationships. This paper considers Lance in the context of Gay representation in media of the 1970s, and then explores the struggle of the filmmakers--and the Loud family themselves--to control and contain the public perception of Lance. The often vague and allusive comments by Lance＇s parents and even Lance himself suggest a character that is at once channing, witty, and vibrantly alive, yet also pretentious and deceitful. The final argument is that these complicit efforts to avoid controversy actually engender it, turning Lance Loud into a figure of mystery and conjecture ... and the undisputed star of the series.展开更多
