The limited transferring moment capability of Glulam (glued laminated wood) joints results in insufficient joint stiffness. Therefore, most the connections are hinged joints. Based on previous studies, one novel end-connection device was proposed to form prestressed continuous beams. beams were composed low-relaxation steel bars, deviator block, anchorage device, and apparatus. These bars tensi...

Abetract-Experiments involving the ejection of beams of electrons from spacecraft have been performed for more than 2 decades in order to study fundamental plasma physical processes as well as for a range of diagnosticand application-oriented purposes. This paper reviews some of the key issues that have been pursued in the past 10 years. These include questions regarding spacecraft charging and...
