Miami Pedestrian Bridge Collapse: Computational Forensic Analysis
(ASCE, 1/1/2020 1)On March 15, 2018, a pedestrian concrete truss bridge in Miami, Florida, collapsed during construction. The failure of this bridge caused multiple casualties and raised many serious concerns regarding the design and ... -
Extended Formulation of Stress Concentration Factors for CFST T-Joints
(ASCE, 1/1/2020 1)In previous research, the authors numerically investigated 212 finite-element (FE) models of concrete-filled steel tubular (CFST) T-joints under axial force in the brace to derive formulae for stress concentration factors ... -
Tuned Mass Dampers for Wind-Induced Vibration Control of Chongqi Bridge
(ASCE, 1/1/2020 1)Chongqi Bridge is part of an important route over the Yangtze River connecting Chongming City in Shanghai with Qidong City in Jiangsu. The steel box-girder bridge consists of separate but adjacent twin six-span bridges, ... -
Wind-Induced Stability of a Cable-Stayed Bridge with Double Main Spans of 1,500 m and a Twin-Box Section
(ASCE, 1/1/2020 1)Both aerostatic torsional divergence and flutter are challenging for the wind-resistant performance of long-span cable-stayed bridges. Aiming at a cable-stayed bridge with double main spans of 1,500 m each and a typical ... -
Shear Strengthening of Corroded RC Beams Using UHPC–FRP Composites
(ASCE, 1/1/2021)In this paper, ultrahigh-performance concrete (UHPC) combined with fiber-reinforced polymer (FRP) composites is proposed for the shear strengthening of corroded reinforced concrete (RC) beams. The UHPC–FRP composites are ... -
Methodology for Load Rating of Damaged Double-Tee Girder Bridges
(ASCE, 1/1/2021)The most common type of bridge on South Dakota local roads is a precast prestressed double-tee (DT) girder bridge. For old and/or deteriorated bridges, the estimation of the bridge safe live load is necessary to ensure the ... -
Bending Stiffness Identification of Simply Supported Girders using an Instrumented Vehicle: Full Scale Tests, Sensitivity Analysis, and Discussion
(ASCE, 1/1/2021)Static load tests are currently essential to assess the actual response of prestressed concrete bridges: the bending stiffness is indirectly estimated from deflection measurements under loading. In this paper, to overcome ... -
Fatigue Performance of Butt-Welded Tensile Plate Cable-Girder Anchorages of Long-Span Cable-Stayed Steel Box Girder Railway Bridges
(ASCE, 1/1/2021)The fatigue performance of a new type of butt-welded tensile-plate cable-girder anchorage that requires higher load-bearing capacity and lower stress concentration compared with normal tensile-plate anchorages for a long-span ... -
Composite Steel Tee Concrete Deck Bridge System: Design, Fabrication, and Full-Scale Verification
(ASCE, 1/1/2021)A short-span highway bridge system composed of steel tee sections embedded in a concrete deck slab during fabrication of the member was developed for the Pennsylvania Department of Transportation. The connection between ... -
Dynamic Model Testing of Low-Gravity-Center Cable-Stayed Bridges with Different Girder-to-Tower Connections
(ASCE, 1/1/2021)To investigate the seismic response characteristics of low-gravity-center cable-stayed bridges with twin towers, a simplified mechanics model was established based on the transmission path of the horizontal seismic inertial ... -
Revisited Live Load for Simple-Span Bridges
(ASCE, 1/1/2021)Twenty-five years ago, a bridge live-load model was developed along with the calibration of the AASHTO LRFD Specifications. The statistical parameters of truck loads were based on the Ontario, Canada, truck survey performed ... -
Deep Learning Framework for Total Stress Detection of Steel Components
(ASCE, 1/1/2021)Accurately obtaining the stress of steel components is of great importance for the condition assessment of civil structures. Currently, methods for structure stress detection have some drawbacks such as the capability of ... -
Experimental Characterization of Static Behavior of a New GFRP–Metal Space Truss Deployable Bridge: Comparative Case Study
(ASCE, 1/1/2021)A new glass fiber-reinforced-polymer (GFRP)–metal box-truss composite girder was developed for use in lightweight deployable vehicular bridges with favorable torsional resistance for large spans. This paper describes the ... -
Reinforcement Effect of High-Strength Bolts for Stop-Hole under Out-of-Plane Bending Loads
(ASCE, 1/1/2023 1)The base metal at a stop-hole edge will be in out-of-plane torsion under bending loads to resist bolt tightening and weaken the reinforcement effect. By carrying out numerical simulation and fatigue tests, the effect of ... -
Using Full-Scale Observations on Footbridges to Estimate the Parameters Governing Human–Structure Interaction
