Secondly, a phase to be given to each transmission antenna forming a phased array is calculated to direct a transfer beam
of 5.8 GHz toward the MAV.
There were no witnesses but Ministry of Labour investigators claim there was inadequate clearance between the spool of the moving paper reel and a transfer beam
stand to ensure safety of any worker in the area.
Support is provided at the bottom by a horizontal transfer beam
resting on sculpted concrete columns and at the top by steel members tied back to the main concrete frame.
Instead, new column spacing and transfer beam
arrangements were designed.
Each beam required around 168m3 of concrete, while one huge transfer beam
at second floor level required around 360m3, Salib said.
The transfer beams
were then stressed to increase their structural loading capacity, using concrete's natural compressive strength to rapidly acquire tensile strength.
The area consists of a long 25m (82 feet) by 33m (109 feet) span achieved with post-tensioned concrete transfer beams
2.3-2.8m (7.5 to 9 feet) in depth.
The structural system includes massive long-span transfer beams
with depths of up to 36 inches, which support columns above the lower level ballroom.
At times, columns and heavy transfer beams
appear in the most baffling positions.
The removal and replacement of the existing slab, together with the removal of selected columns and installation of transfer beams
, made the lab structurally more flexible.
This worked very well with the interior architecture and also avoided major transfer beams
in the floors."
