Modeling of Inelastic Behavior of RC Structures under Seismic Loads
Proceedings of the U.S.–Japan Seminar on Post-Peak Behavior of Reinforced Concrete Structures Subjected to Seismic Loads: Recent Advances and Challenges on Analysis and Design, held in...

Stronger Longer
Like many older concrete bridges, the Sierrita de la Cruz Creek Bridge, a 1957 crossing near Amarillo, Texas, suffered from concrete deterioration. When the Texas Department of Transportation...

Redesigning the San Roque Dam
Engineers updated a 20-year-old design for the San Roque Dam in the Philippines to save time and money and improve the dam's ability to withstand earthquakes. The structure...

Symptom-Based Reliability of Aging Infrastructure Systems
Ideally, aging infrastructure systems should be monitored for safety and repaired in case of need. Eventually, authors believe that symptom-based reliability will be useful for safety...

Smart Online Structural Monitoring and Diagnosis
(abstract only) This paper describes the observation matrix as innovative monitoring and diagnosis: (1) The matrix elements of the observation matrix multiplied by its transposed serve...

Cross-Frame and Diaphragm Behavior in Skewed Bridges
The author examines the existing specifications and guidance for bracing provisions by AASHTO, AISC, and TxDot, and the need for developing bracing requirements....

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...

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....

Blast Mitigation Research and Technology Transfer
Terrorists continue to use bombs as a weapon of choice. Recent bombings targeted against the United States, such as the World Trade Center, Murrah Federal Building, Khobar Towers, and...

New Concepts in Structural Strength Assessment for Large Buildings in Fire
This paper presents theoretical descriptions of the key phenomena that govern the behaviour of composite framed structures in fire. These descriptions have been developed in parallel with...

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...

Update of Serviceability Design Considerations for Low-Rise Steel Buildings
In 1990, the American Institute of Steel Construction published Servicability Design Considerations for Low-Rise Buildings by James M. Fisher and Michael A. West. This document was published...

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...
