Abstract: A simplified method to analyze pin-ended girders as uniformly loaded members is presented. This method is shown to conservatively estimate the maximum moment, shear, and deflection of the girder without needing any of the ...

Abstract: A frequency‐domain investigation into the effects of nonuniform earthquake excitation on the response of a three‐dimensional arch dam‐water‐foundation system is performed. The analysis consists of two parts. First, the ...

Abstract: Design and construction of a structure on the Moon requires addressing a host of issues not encountered on Earth. Since there is no atmosphere on the Moon, a lunar structure must contain an artificial atmosphere. One ...

Abstract: A modular inflatable structure consisting of thin, composite membranes is presented for use in a lunar base. Results from a linear elastic analysis of the structure indicate that it is feasible in the lunar environment. ...
