An Experimental Study of Active Structural Control
An experimental investigation is made concerning the possible application of active control to structures under seismic excitation. The experimental facilities and structural model are...

Optimum Seismic Structural Design with Tendon and Mass Damper Controls and Random Process
This paper describes the optimization of structural weight for seismic structures implemented by active control systems. The instantaneous open-loop optimal control algorithm is used for...

Olmos Dam Modifications
(1981 OCEA Nominee.) The 55-year-old Olmos Dam, five and one-half miles northeast of San Antonio, Texas, required major modifications to avoid...

Protecting Post-Tensioning Tendons in Concrete Structures
Patterns of corrosion problems related to tendon systems are analyzed based on the author's experience in evaluating over 50 corrosion related performance problems in prestressed...

Dam Anchored to Foundation to Withstand Floods
Federal Power Commission Order No. 315 required a safety review of Conowingo Dam and Powerhouse by an independent board of consultants. As recommended by this board, a study was made of...

Steel Stress-Ribbon Concept�� Will It Save Money�
The stress ribbon structure, a fairly new and unusual concept, can be built with central sags of less than 2% of the span length using currently available materials and technology. Possibilities...
