Seismic Retrofit of Existing Reinforced Concrete Columns by Glass-Fiber Composites

New Concept for Wrapping Columns with a High Strength Fiber/Epoxy System

Columnless in Chicago
The United Center in Chicago is now home to the Bulls basketball team and the Blackhawks hockey team. The arena features luxury suites, a column-free interior and unobstructed views. An...

Assessment and Testing of Column Lap Splices for the Santa Monica Viaduct Retrofit
This paper describes assessment and the full-scale test of a 3 ft. (914 mm) dia. column containing #11 (34.9 mm dia.) reinforcing steel lap-spliced in the critical region. The column modelled...

Seismic Strengthening of R/C Columns Using Steel Jackets
This paper presents experimental results on the use of steel collars and steel jackets as a retrofitting system to improve the seismic performance of short rectangular reinforced concrete...

Ductility Analysis for Seismic Retrofit of Multi-Column Bridge Structures, Santa Monica Viaduct
A new procedure is being developed for the ductility analysis of multi-column bridges. The formation of the plastic hinges in the structure (columns and/or superstructure) is followed...

Seismic Behavior of Weak-Column Strong-Beam Frames
An experimental evaluation of the seismic performance of moment-resisting steel frames using Weak-Column Strong-Beam joints is described. A simulated seismic response is imposed on five...

Some Unresolved Issues in Seismic Steel Codes
In the latest revisions of the three major U.S. seismic codes (AISC, NEHRP, UBC) some requirements can be questioned because of limited knowledge. Confining attention to conventional kinds...

A Wind Tunnel Study of an Aeroelastic Model of the Florida Suncoast Dome
Very large scale cable domes have been built using prestressed, high strength steel cable or strand, steel tube columns and a lightweight fiberglass skin. Geiger Engineers Florida Suncoast...

Seismic Behavior of High Strength Concrete Columns
Information on the ductility of high strength columns in seismic areas has been scarce. The available information is based mainly on small test columns subjected to monotonic concentric...

High-Strength Concrete Joints Under Cyclic Loading
This experimental investigation was undertaken to check the validity for high-strength concrete beam-column joints of recommendations made by ACI-ASCE (American Concrete Institute-American...

Long-Span Design for Seismic Forces—A Case Study of the Anaheim Arena
The design for the Anaheim Arena roof evolved in response to the strict requirements for a structure in a seismic zone 4 location. The support of the 329 ft. (100 m) by 444 ft. (135 m)...

Blast-Damaged Concrete Structures in Beirut
This paper describes the effect of blasting loads on structural members. It identifies predominant structural systems in war-damaged zones of Beirut and to explain typical damage mechanisms....

Joint Design in Composite Columns/Steel Beam Structures
The use of a composite building system, utilizing a composite exterior column and a concrete spandrel beam system, proposed by Dr. Fazlur Khan in 1967, is recalled. In the last 25 years,...

Axial Capacity of Concrete Infilled Steel Box Column with Biaxial Bending
The objective of this study was to investigate the feasibility of using the Bresler reciprocal load method to calculate the axial capacity of a concrete infilled steel box column subjected...

Buckling of Guyed Towers
The buckling load of a column guyed in a plane by symmetric guy wires is considered. The column is built-in at the ground, supported at the top by guy wires, and is loaded by a vertical...
