Field Tests of Two Prestressed-Concrete Girder Bridges for Live-Load Distribution and Moment Continuity
(American Society of Civil Engineers, 2016)Two similar bridges constructed with a live-load continuous connection were tested for live-load distribution and joint continuity. Girder distribution factors (GDFs) were compared with AASHTO equivalent values. For positive ... -
New Framework for Risk-Based Inspection of Highway Bridges
(American Society of Civil Engineers, 2016)This paper presents a new methodology for determining bridge inspection intervals and procedures. The methodology was developed using established risk-based methodologies with the goals of improving bridge safety and ... -
Effects of Solar Temperature Gradient on Long-Span Concrete Box Girder during Cantilever Construction
(American Society of Civil Engineers, 2016)Three-dimensional (3D) finite-element analysis of a 106 × 200 × 106-m concrete box girder was conducted to study the effect of solar temperature gradients on long-span bridges during construction. Segments over the internal ... -
Shaking Table Performance of a New Bridge System with Pretensioned Rocking Columns
(American Society of Civil Engineers, 2016)A new bridge bent system has been developed to reduce on-site construction time, minimize residual displacements even after a large earthquake, and reduce seismic damage in comparison with conventional cast-in-place ... -
Rapid Repair of Earthquake-Damaged RC Columns with Prestressed Steel Jackets
(American Society of Civil Engineers, 2016)In this study, a lightweight prestressed steel jacket (PSJ) was proposed and developed for rapid and cost-effective repair of a severely damaged circular reinforced concrete column. The PSJ is composed of several prestressed ... -
Cyclic Response of Precast Bridge Piers with Novel Column-Base Pipe Pins and Pocket Cap Beam Connections
(American Society of Civil Engineers, 2016)Prefabrication of structural elements is the integral part of accelerated bridge construction (ABC). Providing constructible beam-column and column-foundation connections that can tolerate inelastic cyclic deformations is ... -
Bridge Information Modeling for Inspection and Evaluation
(American Society of Civil Engineers, 2016)This paper presents a method and prototype implementation for tracking and assessing the structural condition of bridges. The method uses building information modeling (BIM) software to link and analyze data related to the ... -
Optimization Indexes to Identify the Optimal Design Solution of Shell-Supported Bridges
(American Society of Civil Engineers, 2016)As a structural optimization technique, topology optimization is an important tool for helping designers to determine the most suitable shape of a structure. With this powerful tool, designers can define families of candidate ... -
New Bridge Forms Composed of Modular Bridge Panels
(American Society of Civil Engineers, 2016)Panelized bridge systems (e.g., Bailey, Mabey Johnson, Acrow) are intended for girder-type bridges and have been implemented for military, civilian, and disaster relief applications. Design challenges, however, include ... -
Bridge Decks with Precast UHPC Waffle Panels: A Field Evaluation and Design Optimization
(American Society of Civil Engineers, 2016)The first full-depth precast ultrahigh-performance concrete (UHPC) waffle panels have been designed and implemented in a bridge replacement project to use accelerated bridge construction and increase bridge deck longevity. ... -
Vertical Crowd–Structure Interaction Model to Analyze the Change of the Modal Properties of a Footbridge
(American Society of Civil Engineers, 2016)In this paper, a biomechanical crowd–structure interaction model is proposed and further implemented to adequately estimate the energy exchange between pedestrians and a footbridge. The proposed model focuses on the ... -
Performance of Pedestrian-Load Models through Experimental Studies on Lightweight Aluminum Bridges
(American Society of Civil Engineers, 2016)Aluminum structures provide a high strength-to-weight ratio, are corrosion resistant, and are esthetically pleasing. Hence, their use in bridge construction has recently begun to increase, especially for pedestrian bridges. ... -
Scour Effect on Bridge and Vehicle Responses under Bridge–Vehicle–Wave Interaction
(American Society of Civil Engineers, 2016)Bridge scour is a major cause of bridge failures and has emerged as a significant concern for bridge engineers. Most studies focus on the scour mechanism, modeling, detecting and monitoring, and countermeasures. To detect ... -
