    Transcript of a letter by an unidentified author to David Fentress regarding sharing federal newspapers and the banning of federal newspapers in some areas. The author passes on the news of the war including the destruction of the Federal merchantmen by the Confederate fleet. He passes along world news: Russia preparing to go to War with Europe and how that could negatively affect the Confederacy. There is also speculation on the future of the war

    A control volume based formulation of the discrete Kirchoff triangular thin plate bending element

    No full text
    A control volume method is presented for predicting the displacement and rotation of thin transversely loaded flat plates. The new procedure uses discrete Kirchoff triangle (DKT) elements but introduces a dual mesh of interconnected control volumes (CVs) centred on the finite element (FE) vertices. Discrete equations for the unknown degrees of freedom are subsequently derived by enforcing equilibrium on these CVs; as such this implementation is a quadrature free routine. To allow a comparison, a quadrature free implementation of the DKT element, using the standard finite element procedure, was developed using symbolic methematics. The CV based procedure is validated by patch tests for a state of pure bending and twist. Convergence tests for various loading types show enhanced performance for coarse meshes over the equivalent FE method

    David Zimmer Christmas letter

    No full text
    This Christmas letter written November 30, 1999, by David Zimmer is titled "Season's Greetings from the last of the Red-Hot-Santas!" It features an illustration of Santa Claus with a guitar, and a summary of Zimmer's year. David Zimmer (1929-2005) was born in Harrisburg, Ohio. He enlisted in the U.S. Army and served for two years during the Korean War at the Brooke Army Medical Center in San Antonio, where he performed in drag for wounded soldiers. After the war, he returned to Ohio. Zimmer performed as Dolly Divine, a name inspired by the song "Hello Dolly." In 1964, he established the Berwick Ball with Orn Huntington, another important early gay activist in Central Ohio. The Ball began as a formal Halloween costume ball that provided a safe space to gather and enjoy drag shows for the gay community each year; over the years, it grew into an annual Halloween tradition and an important fundraiser for the AIDS movement and other charities. During the 1970s, Zimmer was also known for hosting lavish parties at his Harrisburg home. In 1989, he moved to the German Village area of Columbus where he remained active in the community. During the 1990s, Zimmer continued to perform in and out of drag and commissioned costume designer Dick Frank to make elaborate outfits. Zimmer worked for Huntington National Bank for 39 years and was a member of the Harrisburg United Methodist Church, Veterans of Foreign Wars and the German Village Society

    Investigation of cold-formed steel top-hat sections under bending

    No full text
    In recent years, with the introduction of higher strength grades, cold-formed steel sections have become increasingly more slender. As a result, top-hat purlin sections have become an alternative to conventional zed purlins, particularly when smaller purlin spans (around 4 m) are required. Such top-hat sections are torsionally stiffer than zed purlins, and have greater resistance against lateral-torsional buckling. Furthermore, they do not require anti-sag rods. However, when determining their strength, they are susceptible to buckling. In this paper, a combination of full-scale laboratory tests and finite element analyses are used to investigate the bending strength of such top-hat sections. Both upward and downward loading conditions are considered. In this paper, twenty-seven full-scale experimental tests on top-hat sections are described. The moment capacities obtained experimentally are compared against those predicted by the Eurocodes and non-linear elasto-plastic finite element analyses
