stiffener

[′stif·nər]
(civil engineering)
A steel angle or plate attached to a slender beam to prevent its buckling by increasing its stiffness.

stiffener

1. A secondary member, usually an angle iron or channel, 1, attached to a plate or sheet to increase its stiffness and to prevent buckling.
2. In a hollow-metal door, the internal reinforcement for door panels; usually channel iron.

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 [19], is recommended to adopt no less than:
In 2012, Hosseinzadeh and Tehranizadeh [7] 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 [8], 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 require.
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.
