Noncondensable Gas Composition and Outgassing Rates in the Open-Cycle OTEC System with Direct-Contact Condensation
This paper will present the results of recent measurements of noncondensable release from an open-cycle ocean thermal energy conversion (OC-OTEC) system in a direct-contact condensation...
Optimum Removal of Noncondensable Gases for Open Cycle OTEC System
For an open cycle OTEC system the dissolved gases in warm surface seawater are evolved in the flash evaporator. Those behave as noncondensable gases in the condenser and degrade the condensing...
De-Aeration and Re-Injection of Noncondensable Gases in Open-Cycle OTEC
Non-condensable gas exchange characteristics in seawater and fresh water are compared and contrasted. The higher rate of exchange observed for these gases in seawater is incorporated in...
Repair of an Improperly Detailed Masonry Facade: A Case History

A Seawall for Sea Mammals
With glass walls only 75 ft from Lake Michigan, an aquarium addition demanded solid seawall protection. Yes, in a strange twist of logic, the first step in creating a whale habitat for...
Building in Reservoirs
The Croton Supply System, one of the three major water supply systems for New York City, is undergoing extensive rehabilitation. In an innovative use of space, some of the new construction...
High Tech on Campus
Hannan Hall, the new laboratory building at The Catholic University of America, has a structure entirely made up of precast concrete panels and 24 in. deep double tees. The loadbearing...
Buckling of Tapered Columns by P-Version of F.E.M.
The local, distortional, overall, and interactive buckling of tapered, thin-walled members under axial compression and flexure are considered by using three-dimensional models based on...
Evaluation and Remediation of Construction Defects in Tilt Wall Panels
Both the surface appearance and structural safety were of concern to the Owner of a five year old warehouse structure that was experiencing delamination of tilt-up wall panels. Delamination...
Concrete Residential Construction in Baja, Mexico
Mexicali, Mexico has experienced earthquakes of magnitude 6.0 to 7.6 on the Richter Scale. A popular and readily available residential construction material is reinforced concrete comprised...
Lateral Force Distribution in Manufactured Housing from Full-Scale Testing
The research focused on the behavior of two manufactured 14 ? 66 ft houses under simulated wind loads. Extensive instrumentation was employed to insure the collection of data that would...
Panel-Sheathed Shear Walls ? Past and Future
In order for a building to resist the lateral forces caused by wind or earthquake, it is necessary that the building include a lateral force resisting system. When the walls are designed...
A Structural Analysis Model for Timber Shear Walls
A numerical modelling procedure for the non-linear analysis of timber shear walls is presented. The model includes the non-linear behavior of the connectors between the sheathing and framing,...
