Abstract: A method for shape selection for lattice structures is reported. The method uses static joint equilibrium equations to determine a minimum set of adjustments to lattice geometry needed to achieve equilibrium reference ...

Abstract: Nondestructive inspection of structures by modal analysis of vibration response is reported. The dependence of natural frequencies and modal damping coefficients on deterioration in structures is examined. The magnitude ...

Abstract: A basis for the direct use of data from nondestructive evaluation methods in bridge management systems is presented. Bridge management systems use integer-valued condition ratings to recognize conditions of bridge elements, ...

Abstract: As a part of the construction of Interstate 70 through Glenwood Canyon, in Colorado, three new types of barriers for protection against rockfall were developed through a program of prototype testing, numerical simulation ...
