On April 9th, in a statement to staff, he insisted he had upheld the rules, but pointed out that Ms Riza's case was "unprecedented", in part because her external posting was involuntary and for longer than usual.
This is the first time Facebook has enabled this kind of automatic external posting (historically everything you've posted on Facebook has stayed on Facebook).
Application is made to the time-dependent reliability assessment of a PSC box-girder bridge, and the effectiveness of three strengthening methods including externally bonded steel plates, fibre reinforced polymer (FRP) composites and external post-tensioning is compared.
In this paper, a novel CFRP system for external post-tensioning is presented.
The results have informed the design of strengthening works, using complementary external post-tension.
Section enlargement, bonded steel plating, external post-tensioning and FRP composites wrapping are some of the techniques being widely followed to retrofit various structural elements.
This is especially important in external post-tensioned tendon systems, where the anchorage points are exposed to the full load throughout the life span of the structure.
Witnesses were allowed to leave the scene, cars were moved before being photographed and an external post-mortem was conducted at a nearby mortuary without any detailed forensic checks.
Moreover, in the case of external post-tensioning, it was possible to choose an adapted eccentricity of the tendon profile to optimise the effect of the post-tensioning on the deflection and on the acting shear force.
Strengthening methods such as the addition of new structural elements, steel plate bonding, external post tensioning, steel bracing and many more have been applied with some degree of success.
The results demonstrated that external post-tensioning significantly decreased the stresses in the internal reinforcement at all stages of loading, and hence extended the fatigue life of the strengthened beams.
