Robust Optimization of the Loaded Contact Pattern in Hypoid Gears With Uncertain Misalignments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an automatic procedure to optimize the loaded tooth contact pattern of face-milled hypoid gears with misalignments varying within prescribed ranges. A two-step approach is ...
Seismic Response and Fragility of Deteriorated Reinforced Concrete Bridges
Publisher: American Society of Civil Engineers
Abstract: One of the greatest challenges in the United States today is overcoming the deterioration of an aging infrastructure system. In particular, the highway/bridge infrastructure system has traditionally been neglected of ...
Probabilistic Demand Models and Fragility Curves for Reinforced Concrete Frames
Publisher: American Society of Civil Engineers
Abstract: Fragility curves are constructed to assess the seismic vulnerability of a hypothetical two-story reinforced concrete frame building designed only for gravity loads. Fragility curves are also developed for the same building ...
Basis for ASTM E 1300 Annealed Glass Thickness Selection Charts
Publisher: American Society of Civil Engineers
Abstract: In the early 1980s, a glass failure prediction model (GFPM) was introduced to resolve differences in U.S. industry procedures used to determine the minimum thickness of glass required to resist a specified uniform lateral ...
Seismic Fragility and Confidence Bounds for Gravity Load Designed Reinforced Concrete Frames of Varying Height
Publisher: American Society of Civil Engineers
Abstract: Fragility estimates are developed to assess the seismic vulnerability of reinforced concrete (RC) frame buildings, which were designed primarily for gravity loads. Five buildings of various heights (one-, two-, three-, ...
Seismic Behavior of Composite RCS Frame Systems
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of an experimental investigation into the seismic performance of a composite moment resisting frame system that consists of reinforced concrete columns (with an embedded steel shape for ...
Seismic Behavior of Wood Diaphragms in Pre-1950s Unreinforced Masonry Buildings
Publisher: American Society of Civil Engineers
Abstract: This paper documents an experimental testing program on the lateral in-plane behavior of pre-1950s existing and rehabilitated wood floor and roof diaphragms in unreinforced masonry buildings found in the Central and Eastern ...
Optimization of the Loaded Contact Pattern in Hypoid Gears by Automatic Topography Modification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Systematic optimization of the tooth contact pattern under load is an open problem in the design of spiral bevel and hypoid gears. In order to enhance its shape and position, gear engineers ...
Seismic Design and Constructability of RCS Special Moment Frames
Publisher: American Society of Civil Engineers
Abstract: This paper presents an evaluation in terms of constructability, cost, and seismic performance of an alternative structural system for high seismic risk zones made of composite reinforced concrete-steel (RCS) special ...
