Size Effect in Shear Strength of RC Beams: Experiment, FE Analysis, and Design Formula

Tension Stiffening Effect in RC Beams with Steel Fiber

Shear Performance of Prestressed RC Interior Beam-Column Joints

Beltway Connection
The Woodrow Wilson Memorial Bridge carries the Capital Beltway (I-495) and a part of I-95�the main north�south interstate route on the East Coast�across the Potomac River south of Washington,...

Ground Improvement Feasibility Reports for Large Highway Projects: A Case Study of the Woodrow Wilson Bridge Replacement Project

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....

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...

Evolution of Composite Floor Systems in the United States
Composite floor systems, which combine structural steel beams with a cast-in-place concrete slab, have grown in popularity in the U.S. during the past 40 years. In most early applications,...

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...

Structural Engineering: Beam Connection Designed for Improved Earthquake Response

Cellular Beam Saves Time, Money

Sharp Curves
In Madison, Mississippi, just north of Jackson on Interstate 55, a diamond interchange with State Route 463 has become a bottleneck for commuters and local motorists. But the typical solution�a...

Composites Enhance Timber Bridges
Two relatively new technologies are available for reinforcing or strengthening timber bridges with fiber-reinforced polymers (FRPs). The first consists in reinforcing the tension side...

Extended Life Span
The Harlem River Lift Span�part of New York City's Triborough Bridge System�was the largest vertical span in the country at the time of its construction in 1936. The lift...

Airport on the Move
The Dallas/Fort Worth International Airport (DFW) is building an automated people mover (APM) system as part of a five-year, $2.6-billion capital development program that includes three...
