But defence ministry and industry officials are also treated to a display by United States Air Force F-22 Raptor Aerial Demonstration Team Commander Major Dave Zeke Skalickyky, giving them first-hand views of the two planes' performance.
Since beams in each row of KPC cover the whole 360° plane, performance of the proposed scheme is also tested in the whole cell scenario.
Strengthened walls were tested against blast loads for the evaluation of the out-of-plane performance of strengthened walls as against the unreinforced masonry (URM) walls.
The results show that the ECC-retrofitted specimens exhibited a significant enhancement in the out-of-plane performance in terms of strength, stiffness and deflection compared to the un-strengthened specimens.
In the first seconds after clearing the second wake, "the airplane appears to be consistent with flight control inputs," said Thomas Haueter, the board's deputy director of aviation safety, meaning that the plane's performance still matched the pilot's working of the controls.
The purpose of this experimental program was to investigate the performance of near-surface mounted (NSM) carbon fibre reinforced polymer (CFRP) strips as a seismic retrofit solution for improving the out-of-plane performance of walls in URM buildings.
Although being considered non-structural elements, during an earthquake this type of elements tends to interact with the reinforced concrete surrounding frames, which canresult in different types of in-plane damage, namely diagonal cracking, corner crushing, shear-friction failure which significantly reduce the out-of-plane performance of such type of elements.
However existing literature provides little guidance as to the improvement level that could be expected, especially with respect to out-of-plane performance.
It would therefore be interesting to assess if any improvements in pathways important in inclined plane performance (such as vestibulospinal and reticulospinal tracts) could be detected electrophysiologically in order to determine if LV-ChABC is differentially affecting various spinal pathways.
Potential customers had liked the additional seating capacity, but balked at the plane's reduced performance, resulting from its extra weight, he said.
