Cyclic Behavior and Seismic Design of Steel Base Plates
The objectives of this study were to conduct realistic experiments to understand cyclic behavior of steel column base plates and to develop seismic design recommendations. Six specimens...
A Comparison of the Cyclic Performance of Bolted and Riveted Connections
As part of a larger project to investigate the performance of older steel frames, a comparative study of bolted and riveted T-stub connections was conducted. The study included connections...
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...
Prediction of Wind-Induced Responses and Wind Loads
The Recommendations for Wind Loads of Buildings and Structures of the Architectural Institute of Japan have now been updated. This paper presents the drafts of the new Recommendations...
Wind Resistant Design and Response Control of Tall Building
This paper presents an overall view of the wind resistant design and response control of the tall buildings in Japan, the Crystal Tower in Osaka and the Landmark Tower in Yokohama. The...
Tuned Mass Damper in Tall Building Design
Viscoelastic dN and tuned mass dampers are often used by tall building designers to control wind-induced building vibrations resulting from such phenomena as vortex shedding, galloping,...
Vortex Shedding Induced Fatigue Fracture of Mast Tower
The fracture of a pair of 60m high circular steel masts is investigated. The design criteria and fabrication practices are reviewed. The cause of failure is related to the fatigued condition...
85 Stories in Kuala Lumpur?The 5th and 6th Tallest Buildings in the World
A concrete core and cylindrical concrete tube structure provides a safe, elegant, efficient and constructible solution to the challenge of designing the world's 5th and 6th tallest buildings,...
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...
Orthotropic Rigidities of Curved Concrete Waffle Slabs
Analytical expressions are derived for predicting the flexural and torsional rigidities during the pre-cracking and post-cracking stages for horizontally- curved waffle slab structures....
Steel Plate Energy Absorbers for Improved Earthquake Resistance
This paper discusses results of an combined experimental and analytical investigation on seismic response of frame structures using welded steel triangular plates as added damping and...
Response of Equipment in Structures Supported on Resilient-Friction Base Isolators Subjected to Ground Motion
In this paper, the response of equipment in structures on a particular friction-type device, the resilient-friction base isolator, is examined. The R-FBI is composed of layers of Teflon...
Evaluation of Seismic Isolation Schemes for a Historic Building
The U.S. Court of Appeals Ninth District building originally completed in 1905 with an expansion in 1933, suffered damage during the 1989 Loma Prieta earthquake. The building is currently...
Seismic Base Isolation Design for the San Bernardino County Medical Center Replacement Project
The SBCMC Replacement Project, located in Colton, California, consists of six separate building structures containing a total of approximately 86,000 m2...
Diagnosing Lateral Strength of Existing Concrete or Masonry Buildings
A research prospectus is presented for improving present methods of structural evaluation for concrete and masonry buildings. Specifically, the proposed research plan is limited to strength...
Behavior of Horizontally Curved Steel Highway Bridges
Horizontally curved highway bridges represent up to 25 percent of the market for new steel-bridge construction each year. However, unanswered questions remain concerning the fundamental...
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,...
Seismic Strengthening for Structures in Regions of Low Seismicity
Most existing structures were not designed to today's seismic codes and standards, and in fact in low seismicity regions codes did not require seismic design until recently....
