Reducing Settlement Risks in Residual Piedmont Soils Using Rammed Aggregate Pier Elements

Seismic Design of Highway Bridges: Recommended Specifications
Under the AASHTO-sponsored National Cooperative Highway Research Program (NCHRP), a joint venture of the Applied Technology Council and the Multidisciplinary Center for Earthquake Engineering...

Maintenance of Diaphragm-Girder Connections
Fatigue cracking at diaphragm-girder connections and at similar connections of cross-frames and floorbeams have been common in steel highway bridges for the past 20 or 30 years. Fatigue...

A Framework for Performance-Based Seismic Design
The following probabilistic framework for seismic performance assessment is presented as an effective foundation for the development of performance-based guidelines. It suggests a generic...

Effect of Column-to-Beam Strength Ratio on Seismic Performance of RC Moment Frames
Reinforced concrete (RC) moment frames are often used in building applications. During strong earthquake excitations, such buildings have been subject to soft-story or column sidesway...

Fragility Curves and Seismic Loss Estimation Methodologies Based on Insurance Data
Loss data for single family dwellings from the 1994 Northridge, California, earthquake were correlated with ground motion with the aim of determining ground motion-based fragility curves....

The Effect of the Slab on Beam-Column Joint Behavior
The three-dimensional effect of slab interaction on frame behavior has been observed in lateral load tests on beam-column-slab elements....

New Developments in the Field of Seismic Isolation
This paper will concentrate onwhat likely, is the most significant of these issues: changes in the mechanical properties ofseismic isolation and energy dissipation hardware as they are...

Performance of Masonry in Disasters: Lessons Learned and Research Needs Identified
This presentation described in this extended abstract is one of several in a panel discussion entitled Enhanced Research in Masonry. The objectives of the presentation are to discuss the...

Seismic Analysis and Retrofit of the Amoskeag Bridges
In 1983 AASHTO first offered the design guide for seismic analysis of bridges, which ultimately became a permanent part of the AASHTO Bridge Design Manual in 1990. Prior to this time,...

Cyclic Behavior of Three-Dimensional Partially-Restrained Composite Connections
This paper describes the test of a full-scale, bi-directional, PR composite beam-to-column connection. The PR connection consisted of continuous reinforcement bars across the column and...

Selected Geotechnical papers of James K. Mitchell
Civil Engineering Classics
Sponsored by the Geo-Institute of ASCE. This collections contains 35 key papers by James K. Mitchell during his extraordinary career as a geotechnical...

Geotechnical Testing, Observation, and Documentation
A geotechnical report, field and laboratory testing, as well as observation and documentation are all integral parts of most geotechnical projects. A technician is usually dispatched to...

Holding Steady
The San Diego—Coronado Bay Bridge is an unmistakable landmark that frames the skyline of downtown San Diego, providing a vital link between the mainland and the Coronado peninsula. The...

Competitive Edge
A new design system called the simplified economical bridge design (SEBD) makes steel cost-competitive with concrete for short- and medium-span bridges for the first time. In fact, a comparative...

High-Tech Inspection
The Federal Highway Administration's National Bridge Inspection Program requires the states to report the condition of its bridges as determined by visual inspection, and...

Going Against the Grain
Conventional wisdom has it that granular soils perform better in mechanically stabilized earth (MSE) wall systems. Their properties are well known and simple to express in mathematical...

Evaluation Findings for Seismic Energy Products, L.P. Elastromeric Isolation Bearing
Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Service Center. This report presents the results of a detailed evaluation...

Evaluation of SSET
The Sewer Scanner & Evaluation Technology
Prepared by CEITEC, a CERF innovation center serving the engineering and construction industries. This report describes an evaluation of Sewer Scanner...

Environmental Technology Verfication Report for Installation of Silt Fence Using the Tommy Static Slicing Method
