“Development of LPA-based free-electron lasers is an important stepping stone to other applications of this technology, such ...

Tests on beams with span-to-overall-depth ratios of 1.0 to 3.3 eliminated 70% of diagonal rebar in coupling beams and used only special column-type confinement at the beam ends. Better yet ...

The coupling's three-piece design handles small amounts of axial motion (0.005 in.) but prohibits use in push-pull applications. Speeds are limited to about 4,000 rpm.

Each specimen consisted of a precast, rectilinear coupling beam, in a vertical position, connected to two large rectilinear blocks that simulated end regions of two linked walls. The main ...

All coupling beams in the 1.5 million-square-foot Lincoln Square Expansion -- which includes luxury condos, a hotel, dining, retail and office space in two 450-foot towers in the heart of Seattle ...
