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...

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,...

Rehabilitation of the Packers Falls Bridge
The Packers Falls Bridge was constructed in 1912 and consists of a 42' (12.8m) single span, reinforced concrete arch structure. This bridge was constructed using a unique forming system...

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...

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...

Integration of Watershed and Ecological Site Land Classification Scales Using GIS Technology
Advanced analysis of hydrologic processes for use in natural resource simulation models and related applications including rangeland health assessments can be facilitated by the integration...

Better BMP Practices
A study of the professional literature indicates that the meaning of the term BMP, literally signifying a Best Management Practice, has diverged, depending on the professional field. Use...

A Full-Scale Seismic Testing Center for Soils and Structures

Phase II Evaluation Findings
The Segmental Concrete Channel Bridge System
Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Innovation Center. This report represents the second component of the...

Moment Resisting Steel Frames—Background to Present Problems

Testing the Load (Available in Geoenvironmental Engineering Special Issue only)
The Pittsburgh District of the U.S. Army Corps of Engineers recently began construction of a new gated dam to replace a nearly 100-year-old concrete fixed-crest dam on the Monongahela...
