CenterCore Strengthening System for Seismic Hazard Reduction of Unreinforced Masonry Bearing Wall Buildings
The CenterCore technique of reinforcing unreinforced masonry walls was developed with the help of a National Science Foundation grant in 1984. The CenterCore strengthening system consists...
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...
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...
