RISNext 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 ...
Assessment of Variable Uncertainties for Reliability-Based Design of Foundations
Publisher: American Society of Civil Engineers
Abstract: LRFD shows promise as a viable alternative to the present working stress design (WSD) approach to shallow foundation design. The key improvements of LRFD over the traditional WSD are the ability to provide a more consistent ...
Resistance Factors for Use in Shallow Foundation LRFD
Publisher: American Society of Civil Engineers
Abstract: In shallow foundation design, the key improvements offered by LRFD over the traditional working stress design (WSD) are the ability to provide a more consistent level of reliability between different designs and the ...
Assessment of Current Load Factors for Use in Geotechnical Load and Resistance Factor Design
Publisher: American Society of Civil Engineers
Abstract: Load and resistance factor design (LRFD) is the standard structural design practice. In order for foundation design to be consistent with current structural design practice, the use of the same loads, load factors, and ...
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 ...
Subharmonic Resonance Cascades in a Class of Coupled Resonators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We consider a chain of N nonlinear resonators with natural frequency ratios of approximately 2:1 along the chain and weak nonlinear coupling that allows energy to flow between resonators. Specifically, the coupling is such ...
Post-Fire Nondestructive Evaluation of a Prestressed Concrete Double-Tee Joist Roof
Publisher: American Society of Civil Engineers
Abstract: Prestressed concrete exhibits resistance to damage induced by fire and associated elevated temperatures, often permitting reuse of structural elements following exposure to accidental fire. However, prudent determination ...
Incorporating Neural Network Material Models Within Finite Element Analysis for Rheological Behavior Prediction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The accuracy of a finite element model for design and analysis of a metal forging operation is limited by the incorporated material model’s ability to predict deformation behavior over a wide ...
