Residual Deformation-Based Performance Evaluation Method for CFST Piers Subjected to Vehicle Collision
(ASCE, 1/17/2023 )Concrete-filled steel tubular (CFST) piers have been applied in bridge structures due to their high bearing capacity, good ductility, and light weight. During their service life, CFST piers may suffer vehicle collision. ... -
Degraded Gerber Saddles in RC Bridges
(ASCE, 12/27/2022)Sudden failure of reinforced concrete (RC) or prestressed concrete (PC) Gerber saddles of bridges and viaducts has occurred all around in the word in the last few years due to corrosion of steel bars. The danger of sudden ... -
Impact-Fragility Analysis of Bridges under Vehicle Collision with Soil–Structure Interaction Effects
(ASCE, 7/12/2023 )Vehicle collision is an important reason for failing urban or highway bridges. However, few works have focused on the probability of damage to a bridge under such extreme loads. In this work, an impact-fragility analysis ... -
Underwater Explosion Resistance Performance of an Old Gravity Dam without Good Longitudinal-Joint Connection Integrity: Coupled Acoustic-Structural Analysis
(ASCE, 5/29/2023 )A gravity dam monolith bounded by the transverse contraction joints on both sides is usually recognized as an independent element in various dynamic analyses. However, in most cases a gravity dam monolith is actually ... -
Rapid Identification and Location of Defects behind Tunnel Lining Based on Ground-Penetrating Radar
(ASCE, 5/24/2023 )Ground-penetrating radar (GPR) is a mainstream tool to detect defects behind tunnel linings, but the difficulty in interpreting GPR signals limits its application. This paper proposes an intelligent way to differentiate ... -
Application of a Data-Driven Intelligent Information System in Infrastructure: Underwater Tunnel Case Study
(American Society of Civil Engineers, 2023/02/01)The intelligent management of infrastructure is crucial to maintain structural stability. Although much more attention has been paid to the development of intelligent systems, the cooperation and efficiency of different ... -
Health-Degree Model for Stagger-Joint-Assembled Shield Tunnel Linings Based on Diametral Deformation in Soft-Soil Areas
(American Society of Civil Engineers, 2023/06/01)In soft-soil areas, excessive transverse deformations have occurred in numerous shield tunnel linings accompanied by serious structural defects. However, to date, a method to effectively diagnose the health status of these ... -
Blast-Resistant Window Anchors. II: Numerical Investigation
(American Society of Civil Engineers, 2023/04/01)A combined experimental and analytical investigation was conducted at the University of Ottawa to assess the performance of blast-resistant window retention anchors to generate design information. The experimental phase ... -
Seismic Collapse Performance of Soft-Story RC Frames with SRC Columns Designed Using the Energy-Based Method
(ASCE, 2022/12/01)Reinforced concrete (RC) structures with weak or soft stories have exhibited poor seismic performance in several past earthquakes, primarily due to high seismic force and deformation demands on the columns in these soft ... -
Building Rectification by Underexcavation and Practical Design Method
(ASCE, 2022/12/01)An 11-story high-rise building with a shear-wall structure utilized a raft foundation based on a deep alluvial deposit. After structure completion, the building tilted beyond acceptable limits. This paper presents the ... -
A Detection Method for Bridge Cables Based on Intelligent Image Recognition and Magnetic-Memory Technology
(ASCE, 2022/12/01)In recent years, more and more disasters caused by the fracture of bridge cables have been reported. Brittle fracture of cables is mainly caused by corrosion fatigue, and thus it is crucial to find cable defects early. The ... -
Safety Assessment of the Community Facilities for the Prevention of Pedestrian Fall Incidents: Concrete Footpaths and Walkways
