A Tribute to Robert Harris Scanlan
Publisher: American Society of Civil Engineers
Damping of Taut-Cable Systems: Two Dampers on a Single Stay
Publisher: American Society of Civil Engineers
Abstract: The mitigation of in-plane stay oscillation in cable-stayed bridges is commonly addressed by placing an external mechanical damper, linear or nonlinear, on each stay or by introducing transverse cross-ties among cables. ...
Damping of Taut-Cable Systems: Effects of Linear Elastic Spring Support
Publisher: American Society of Civil Engineers
Abstract: The influence of linear elastic support on the damper effectiveness of a cable-damper system was investigated by modeling the system as a taut string, an intermediate damper, and a spring in series. Two types of damper ...
Next Generation Space Telescope. I: Design Considerations
Publisher: American Society of Civil Engineers
Abstract: The pointing control system of the Hubble Space Telescope (HST) represents the current state of the art for the precision control of a large spacecraft. The proposed Next Generation Space Telescope (NGST) will require an ...
Aeroelastic Analysis of Cable‐Stayed Bridges
Publisher: American Society of Civil Engineers
Abstract: The aeroelastic response of cable‐stayed bridges to wind is a complex interaction of aerodynamic loading and coupled structural motion. The present paper presents an empirically based analysis method for such structures, ...
A Modified, Slowly Varying Parameter Approach for Systems With Impulsive Loadings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Many oscillating systems in practice are subject to periodic, impulsive loads during their motion. For nonlinear systems traditional methods, such as the slowly varying parameter technique, have ...
Seismic Performance of Joist‐Pocket Connections. I: Modeling
Publisher: American Society of Civil Engineers
Abstract: This paper outlines the development of a technique for the examination of the seismic performance of joist and beam bearing connections in unreinforced masonry structures. An understanding of these “pocket” connections ...
PC‐Based Data‐Acquisition System for structural monitoring
Publisher: American Society of Civil Engineers
Abstract: While personal‐computer‐based data‐acquisition systems have become commonplace in the laboratory environment over the past several years, their use as remote, automatically triggered data‐collection systems has been somewhat ...
Next Generation Space Telescope. II: Proposed Pointing Control System
Publisher: American Society of Civil Engineers
Abstract: The pointing control system of the Hubble Space Telescope (HST) represents the current state of the art for the precision control of a large spacecraft. The proposed Next Generation Space Telescope (NGST) will require an ...
Theory and Full-Bridge Modeling of Wind Response of Cable-Supported Bridges
Publisher: American Society of Civil Engineers
Abstract: As is well known, long, suspended bridge spans require, in the design stage, careful study of their resistance and response to site winds. This has driven, on the one hand, detailed quantitative observation of bridge models ...
