RISJoint Distribution of Wind Speed, Wind Direction, and Air Temperature Actions on Long-Span Bridges Derived via Trivariate Metaelliptical and Plackett Copulas
Publisher: ASCE
Abstract: Comprehensive bridge design should consider simultaneous actions of wind and temperature. The current load combination method of directly superposing extreme wind and temperature actions ignores the correlation between ...
Dead Load Allocation in Triple-Cable Suspension Bridges by Adjusting the Unstrained Lengths of Hangers: A Novel Analytical Approach
Publisher: ASCE
Abstract: Triple-cable design of suspension bridges with an ultrawide main girder can improve their mechanical properties, making it lucrative for numerous engineering scenarios. However, its realization requires assigning an ...
Cable Shape and Construction Parameters of Triple-Tower Double-Cable Suspension Bridge with Two Asymmetrical Main Spans
Publisher: ASCE
Abstract: Triple-tower suspension bridges with two asymmetrical main spans can adapt to complicated terrain conditions. If the top and bottom main cables with different sags are used on the two main spans, the longitudinal constraint ...
Analytical Shape-Finding of the Three-Dimensional Wind-Resistant Rope
Publisher: ASCE
Abstract: Wind-resistant rope systems (WRRS) consisting of wind guys (WGs) and ties are
Aesthetics and Torsional Rigidity Improvements of a Triple-Cable Suspension Bridge by Uniform Distribution of Dead Loads to Three Cables in the Transverse Direction
Publisher: ASCE
Abstract: Suspension bridges with three cable planes provide an excellent solution to the suspension bridges’ downwarp problem with ultrawide decks, which implies their enormous demand and popularization prospect in the engineering ...
Analytical Assessment of the Effects of Multicategory Errors on the Completed State of a Suspension Bridge: Stepwise Multiple Regression Analysis and FEM Validation
Publisher: American Society of Civil Engineers
Abstract: Abstract Starting from bridge design to the construction stage, accumulation of multiple errors
related to manufacturing, installation, material properties, and other factors results
in deviations between the actual completed ...
Coupled Nonlinear Effects of Random Surface Roughness and Rarefaction on Slip Flow in Ultra-Thin Film Gas Bearing Lubrication
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mathematical model of gaseous slip flow in ultra-thin film gas bearings is numerically analyzed incorporating effects of surface roughness, which is characterized by fractal geometry. The ...
Effects of Pine Bark Compost on the Distribution of Cd and Pb in Organic Fractions over Time in Contaminated Soils
Publisher: American Society of Civil Engineers
Abstract: Heavy metal contamination in rural soils severely threatens the food chain, and consequently, human health. The addition of organic amendments to contaminated soils is considered an effective method to immobilize heavy ...
FEM-Based Shape-Finding and Force-Assessment of Suspension Bridges via Completed Loop Adjustment
Publisher: ASCE
Abstract: Finding the main cable shape is an essential step in the design and construction of suspension bridges. In this paper, shape-finding and force-assessment of suspension bridges based on loop adjustment are proposed and ...
Determining Anchor Span Strand Tensions in the Completed State of a Suspension Bridge: An Analytical Algorithm
Publisher: ASCE
Abstract: Integral components of suspension bridges are anchor spans, consisting of separate strands splayed from the main cable between the splay saddle and the front anchor plane. The main cable is separated into several strands ...
