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...
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...
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 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...
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,...
High-Tech Isolation
In the fast-paced world of telecommunications, the time to market is often the deciding factor in the success of an enterprise. With that thought in mind, AboveNet Communications, Inc.,...
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...
Concrete Delivers
The latest addition to the skyline of Shanghai, China, is a strikingly slender all-concrete 62-story office tower. It is the city's tallest all-concrete building, achieving...
