In order to improve the resilience of structures subjected strong earthquakes, a buckling-plate self-centering friction damper (BPSCFD) with low post-yielding stiffness is proposed, which consists group post-buckling plates and variable mechanism. The intended not only reduce peak residual deformation structures, but also limit additional internal force structural elements. Through theoretical ...

BACKGROUND Super-responders to cardiac resynchronisation therapy (CRT) show an exceptional improvement in left ventricular ejection fraction (LVEF). Previous studies showed that apical rocking was independently associated with echocardiographic response to CRT. However, little is known about the association between apical rocking and super-response to CRT. OBJECTIVES To determine the independ...

this study proposes a new linear approximation for solving the dynamic response equations of a rocking rigid block. linearization assumptions which have already been used by hounser and other researchers cannot be valid for all rocking blocks with various slenderness ratios and dimensions; hence, developing new methods which can result in better approximation of governing equations while keepin...

Classic theories of hearing have considered only a translational component (piston-like component) of the stapes motion as being the effective stimulus for cochlear activation and thus the sensation of hearing. Our previous study (Huber et al., 2008) qualitatively showed that rotational components around the long and short axes of the footplate (rocking-like components) lead to cochlear activat...

The asymmetric problem of rocking rotation of a circular rigid disk embedded in a finite depth of a transversely isotropic half-space is analytically addressed. The rigid disk is assumed to be in frictionless contact with the elastic half-space. By virtue of appropriate Green's functions, the mixed boundary value problem is written as a dual integral equation. Employing further mathematical tec...

• Pseudo-static cyclic tests on Cross-Lam Timber (CLT) and Light Frame (LTF) shear walls. Decomposition of the post-elastic displacement into sliding, rocking deformation components. Similarity two structural responses due to same resisting mechanism. A capacity model based sole hold-down reaction seizes overall response. The estimated overstrength factors manifests intrinsic differences betwee...

Over the last decades, performance-based design objectives have shifted towards damage control and continuity of operation after a design-level earthquake. In this context, advantages rocking been applied to development family self-centring systems that can sustain large lateral deformations without noticeable damage. However, bending moments shear forces in uplifting structures increase signif...
