Evaluation of the equivalent slip modulus of nailed connections for application in linear analysis of plywood timber beams

Materials Research, 2008
The study of the stiffness of laterally loaded semi-rigid connections in plywood-timber beams is justified by the influence that the deformation of the connection has on the overall displacements of the structure. Semi-rigid connections are characterized

Stiffness of Concrete-Filled Thin-Walled Steel Tubular Slender Columns

Civil and Environmental Engineering, 2021
Concrete-filled thin-walled steel tubular slender columns are studied in this paper to evaluate their stiffness. The slender columns have various steel tube thicknesses, length/diameter (width) ratios, and concrete compressive strengths.

Reversal of aging-induced increases in aortic stiffness by targeting cytoskeletal protein-protein interfaces [PDF]

, 2018
Background: The proximal aorta normally functions as a critical shock absorber that protects small downstream vessels from damage by pressure and flow pulsatility generated by the heart during systole.

Prognostic relevance of left atrial function and stiffness in heart failure with preserved ejection fraction patients with and without diabetes mellitus

Frontiers in Cardiovascular Medicine, 2022
BackgroundAlthough the left atrium (LA) plays a key role in the pathophysiology and disease progression of heart failure with preserved ejection fraction (HFpEF), the impact of type 2 diabetes mellitus (T2DM) on LA function and stiffness in HFpEF ...

Arterial stiffness

JRSM Cardiovascular Disease, 2012
Measurements of biomechanical properties of arteries have become an important surrogate outcome used in epidemiological and interventional cardiovascular research. Structural and functional differences of vessels in the arterial tree result in a dampening of pulsatility and smoothing of blood flow as it progresses to capillary level.

Seismic performance of ductile corrosion-free reinforced concrete frames

AIMS Materials Science, 2022
Corrosion of steel bars is the main cause of the deterioration of reinforced concrete (RC) structures. To avoid this problem, steel rebars can be replaced with glass-fiber-reinforced-polymer (GFRP).
