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...
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....
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...
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....
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...
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...
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...
Structural Lumber from Small-Diameter Western U.S. Softwood Trees
The purpose of this study was to determine the mechanical properties, and corresponding economic value, of dimension lumber produced from selected over-stocked forest stands of small-diameter...
Small-Diameter Round Timber Connections
An over stocking of trees having diameters less than 20 cm, as measured 1.52 m off the ground presents a major fire hazard to over 54 million acres of National Forest land. Improving the...
Piece by Piece
The Lions' Gate Suspension Bridge, a landmark structure in Vancouver, British Columbia, marks the entrance to one of the busiest harbors on the west coast of North America....
Life at the End of the Tunnel
Deadly tunnel fires in Europe have raised new concerns about tunnel fire safety around the world. Modifications to structures, mechanical systems, and operating procedures can make new...
