Sentence examples for knee elements from inspiring English sources

A total of 12 models with various ranges of knee elements' lengths were investigated.

In this type of bracing, the knee elements assist the system to dissipate energy through the formation of plastic flexural and/or shear hinges within the presented bracing system.

The knee element is placed on one side and at the top of the brace.

In knee braced frames, the braces are attached to the knee element rather than the intersection of beams and columns.

Open image in new window Fig. 3 Section used for knee element in OpenSees software (McKenna et al. 2007).

In this framing system, an especial form of diagonal brace connected to a knee element instead of a beam column joint is investigated.

At small knee lengths, the use of the strong moments of inertia leads to the buckling of the brace; therefore, using the knee element with a small length and a high moment of inertia is not recommended.

However, the knee element is designed to have three plastic joints or two yielded specimens in flexural and shear yielding mode, respectively, for dissipation of the energy caused by a strong earthquake.

In this system the knee element remains in an elastic state during small earthquake and they yield before the main members of the structure in strong earthquakes, and this causes the energy to be dissipated without the lateral strength being attenuated.

The knee element is parallel to the other hypotenuse of the frames in such a way that the ratios b/h and B/H are equal and the along of the bracing member goes through the point at which the beam and the column are connected (Mofid and Khosravi 2000; Mofid and Lotfollahi 2006).

In this system which is called the (KBF), the tag end of the diagonal braces are attached to a skewed (knee) element which itself is attached to the beam and the column or the beam and the support, rather than being annexed to the intersection of the beam and the column.
