RISMain Cable Shape-Finding and Live Load Response of the Suspension Bridge with Central Buckles: An Analytical Algorithm
Publisher: ASCE
Abstract: The stiffness of suspension bridges, which are flexible systems composed of main cables and stiffening beams, is frequently increased by adding one or more pairs of central buckles in the midspan. This study examined a ...
Use of Building Information Modeling in Design to Prevent Construction Worker Falls
Publisher: American Society of Civil Engineers
Abstract: The construction industry has incurred the most fatalities of any United States industry in the private sector in recent years. Whereas many factors may contribute to this statistic, one likely cause is due to designers ...
Axial Compressive Behavior of Square-Section Concrete Columns Transversely Reinforced with FRP Grids
Publisher: ASCE
Abstract: Using grid-type stirrups as transverse reinforcements in reinforced concrete (RC) columns can not only provide higher confinement of the concrete core but also lead to an improved concrete cover and better protection to ...
Numerical Simulation of an Indirect Tensile Test for Asphalt Mixtures Using Discrete Element Method Software
Publisher: American Society of Civil Engineers
Abstract: A three-dimensional discrete element model of an asphalt mixture is developed based on discrete element method (DEM) software to investigate the cracking mechanism of the asphalt mixture, which is validated by the results ...
Cooperative Control of Highway On-Ramp with Connected and Automated Vehicles as Platoons Based on Improved Variable Time Headway
Publisher: ASCE
Abstract: This work investigated the cooperative control of a highway on-ramp under a connected and automated vehicles (CAVs) environment based on improved variable time headway (IVTH). A mainline section with a connected on-ramp ...
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 ...
Static Response Assessment of the Entire Suspension Bridge under Horizontal Transverse Live Load: An Analytical Calculation Method
Publisher: ASCE
Abstract: Long-span suspension bridge is a flexible structure. When subjected to a horizontal transverse live load, its deck undergoes significant transverse bending deformation, jeopardizing traffic safety. This paper proposes an ...
An Analytical Algorithm for Estimating the Deck’s Maximum Deflection and Deck-End Rotation Angle of a Suspension Bridge under Live Load
Publisher: ASCE
Abstract: With the appearance of large-span and heavy-duty high-speed railway suspension bridges, their deck deflections and deck-end rotation angles (DERA) under the live load became very topical indicators of bridge safety and ...
Study on Anti-Slide Stability of Rock Slope along River
Publisher: American Society of Civil Engineers
Abstract: Based on the assumption that the hydrostatic pressure is maximum at half the total groundwater level, which improved the groundwater pressure distribution in the slope body, the safety factor expression for anti-slide ...
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 ...
