Abstract: Changeable message sign (CMS) structures are cantilever, interverted L-shaped structural components that are used to transmit information on road conditions to the driving public. The high-cycle fatigue failure of one CMS ...

Abstract: Changeable message signs (CMS) are supported by cantilevered, inverted L-shaped structural components composed of a vertical post and a horizontal mast arm. The high-cycle fatigue failure of one CMS structure in southern ...

Abstract: New analysis and design procedures have been developed for the performance-based seismic rehabilitation of buildings. Such procedures require accurate estimates to be made of displacements, velocities, and accelerations. ...

Abstract: The response modification factor plays a key role in the seismic design of new buildings in the United States. To date, the values assigned to this factor are based on engineering judgment and have little sound technical ...

Abstract: Charts in technical manuals and standards of practice can be used to compute incident and reflected peak overpressures and scaled impulses generated by a detonation of a high explosive. Design values are reported for ...

Abstract: In the last two decades, several efforts have been made to monitor the cracking behavior in RC structures. A technique that shows promise is acoustic emission (AE). This paper presents the results of an experimental study ...

Abstract: Backbone curves are used in seismic design standards as the basis for developing component models for nonlinear static and dynamic analysis. Herein, data from 240 tests of rectangular, barbell, and flanged shear-critical ...
