Design of Footbridges against Pedestrian-Induced Vibrations
Publisher: American Society of Civil Engineers
Abstract: In 1999 and 2000, the two vibration incidents at the Paris Passerelle Solferino Bridge and the London Millennium Bridge triggered a major revision of existing knowledge concerning footbridge response to pedestrian-induced ...
Probabilistic versus Deterministic Assessment of the Minimum Structural Damping Required to Prevent Galloping of Dry Bridge Hangers
Publisher: American Society of Civil Engineers
Abstract: The risk of large-amplitude vibrations of bridge hangers due to galloping instabilities has posed a challenge to the engineering and research communities. Galloping vibrations can lead to serviceability problems and reduce ...
Untitled
Publisher: American Society of Civil Engineers
Abstract: Galloping vibrations have been identified as potentially problematic for dry stay cables. Three key issues play a major role in the assessment of the structural damping required to prevent galloping of dry stay cables using ...
Design and Calibration of a Large-Scale 155-mm Split-Hopkinson Pressure Bar
Publisher: ASCE
Abstract: The investigation of inhomogeneous materials under dynamic conditions presents several challenges, particularly with regard to testing the dynamic properties of concrete, which requires the use of a large-scale split-Hopkinson ...
Capacity Design and Axial Resistance of Novel Flanged-Plug Bamboo–Timber Composite Members
Publisher: American Society of Civil Engineers
Abstract: AbstractThis paper presents an integrated experimental–analytical framework for a novel bio-based
composite member composed of a Moso bamboo culm with an adhesively bonded, flanged
timber plug. A capacity-based design ...
Concrete Incorporating Recycled Plastic Aggregates: Physical and Mechanical Properties and Predictive Models
Publisher: ASCE
Abstract: This paper presents a pilot study on the characterization of the physical and mechanical properties of a novel green concrete with two different substituted recycled plastic aggregates. A reference mix with an average ...
Characterization of Vertical Wind Profiles Using a Ground-Based Lidar Station in an Open Flat Terrain
Publisher: American Society of Civil Engineers
Abstract: AbstractAccurate characterization of mean wind profiles is essential for optimizing the design
of structures and operation of wind energy systems. This study presents a novel approach
for the identification of mean logarithmic ...
Mortar with Substituted Recycled PET Powder: Experimental Characterization and Data-Driven Strength Predictive Models
Publisher: ASCE
Abstract: The physical and mechanical characteristics of a novel mortar that uses recycled PET powder as a replacement for natural sand are examined in this paper. This study specifically looks at the impacts of replacing recycled ...
