Development and experimental verification of self-centered y-shaped braced frame

Quantification of seismic performance factors of self-centered y-shaped braced frames

“…In the SCY braced frame, since connections are pinned and have no stiffness against rotation, deformation occurs if the length of the SC element changes (see Ref. [16]). Therefore, by increasing the length of the SC element, the effect of the SC element on the overall behavior of the frame increases.…”

“…The discussed mechanism was used in the SCY brace to provide SC behavior. Then, the behavior of the SCY braced frame was studied experimentally and presented in a paper by the authors [16]. In the aforementioned study, to fabricate the specimen, a friction device composed of two plates with a friction pad between them was used to dissipate energy and pre-compressed springs were used to provide the SC characteristic (see Fig.…”

“…As it goes through the second phase, the friction device initiates to slip and stiffness of the frame reduces and the specimen shows different stiffness in two opposite directions. To see the entire details and results of the SCY braced frame, see reference [16].…”
