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...
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...
Gap Analysis for Durability of Fiber Reinforced Polymer Composite in Civil Infrastructure
Prepared by the Civil Engineering Research Foundation. This report provides the results of a study on what is known and not known about the use of...
Closing in on Approval
A lack of qualification criteria and design standards has hindered some engineers from using fiber-reinforced polymers to restore concrete structures. But several organizations�among them,...
Keeping It Together
A new framing system for precast concrete columns and beams will allow tall buildings to withstand large earthquakes without damage to the structural integrity of the building. By using...
Above Them All
The design for what would be the next world's tallest building relies on a 1,550 ft (472 m) high concrete core that will give occupants of the top floors of the building unimpeded...
Branching Out (Available in Structural Engineering Special Issue only)
The Cologne/Bonn Airport in Germany is currently undergoing its biggest construction project to date: a $200 million, five-story addition. Close and productive collaboration between the...
Quality Check
Composite materials, also known as fiber reinforced polymers (FRPs), have traditionally been reserved for aerospace engineering applications because of their high cost. FRPs'...
Emerging Materials for Civil Infrastructure
State of the Art
Prepared by the Emerging Materials Committee of the Materials Division of ASCE. This report presents a review of the state of the art on emerging materials...
Foundation Design for the Elevated Station
The Amundsen-Scott South Pole Station is located at an elevation of 2,850 m on the 3,200 m thick polar plateau, a field of ice and snow that is moving toward the ocean at a rate of 10...
Holding Court
Contractors had their work cut out for them when structural engineers specified concrete-filled steel tubes for the Thomas F. Eagleton Federal Courthouse's perimeter columns....
Isolating the Arts
The LG Kangnam Building in Seoul, Korea, is a multi-use, 140,000 sq m project, consisting of a 40 story, 183 m tall office tower, an adjacent 9-story acoustically base-isolated performing...
Finding the Right Bond
Professors and students from a Swiss university built a dual-span glass fiber reinforced polymer (FRP) bridge to gain a better understanding of how composite materials behave and how best...
Making the Connection
This article details the results of a pilot research project on the use of polymer composites and high-strength adhesives for the structural repair of damaged steel frame connections....
High Rise Express (Available in Structural Engineering Special Issue only)
A new column system developed by the Canam Manac Group in Montreal offers the expediency of steel construction with the economy of concrete. The system is made entirely of lightweight...
Towering Over Xiamen (Available in Structural Engineering Special Issue only)
Composite structural systems are rapidly becoming the preferred choice for high-rise buildings, due to their high strength and stiffness, large ductility, and convenient, economical construction....
Advances in Composite Materials and Mechanics
