Test data indicate that the plastic hinge zone stiffener
is able to develop a very high degree of composite action and to enhance significantly the ductility of the PE beams.
Figure 8 shows that the stress at the fixed-end tends to increase, and the stress at the RBS portion tends to decrease by placing stiffener
. As shortening the length of the vertical stiffener
, the stress around the beam-end reduced, and the stress at RBS portion increased.
The load-displacement curves shown in Figure 10(a) indicate that the longitudinal stiffeners
can distinctly improve the stiffness and the field capacity, and an increase in stiffener
size led to a more obvious improvement.

To highlight the torsional stiffener
restraints on the flange to the web, degree of freedom (DOF) coupling is adopted in the modelling process.
Height [h.sub.r] of one side stiffener
in accordance with p.8.5.9 , is recommended to adopt no less than:
In 2012, Hosseinzadeh and Tehranizadeh  analyzed some finite element models of shear walls without openings and the ones with large openings (as window or door) and stiffener
. In 2013, Alavi and Nateghi , using some experimental models and model of finite elements, investigated a new combination of diagonal stiffeners
and central openings.
It will crinkle up and shrink inside, pulling with it any excess fabric stiffener
that was on the sides of the balloon.
The automatic DBSCs reduce the cost of subsea installation of risers and umbilicals, removing the need for either a dive spread or work-over remotely operated vehicle (ROV) that existing bend stiffeners
The C in the column labels represents the columns and the first four numbers following C respectively designate the steel wall thickness t (mm), diameter of bar stiffener
D (mm), steel wall yield stress [f.sub.y](MPa) and concrete compressive strength [f.sub.c](MPa).
Match the top edge of the fur fabric to the rounded head end of the stiffener
as shown in Photo B.
The Impression embossing is available an any 1.5" bull-hide belt, regardless of whether you have ordered on internal stiffener
of Velcro lining.
