WebOct 5, 2007 · A cable's axial stiffness should always be obtained from the manufacturer, or determined from tests on a sample of the particular cable. ... these two "effective" values is an estimate of the axial stiffness, ie the "AE" value that you would use in the PL/(AE) formula. RE: Modulus of Elasticity for guy wire transmissiontowers (Structural) (OP ... WebIt measures the material's stiffness or its resistance to bend. Stiffness (or rigidity) is one of the most important properties of solid materials. simply modulus. The flexural modulus is represented by the slope of the initial straight-line part of the stress-strain curve. Hence, the ratio of stress to strain is a measure of the flexural modulus.

WebOF ELASTICITY OF CABLES OF CABLE-STAYED BRIDGES UDC 624.2/.8:539.32(045) N. Hajdin1, G.T. Michaltsos2, T.G. Konstantakopoulos2 1 Serbian Academy of Sciences and Arts – Belgrade 2 N.T.U.A. – Athens Abstract. The cables of cable-stayed bridges have a non-linear behaviour caused by their shape variation, when the stress conditions change. WebThe choice of statics model controls the interpretation of the nonlinear bend stiffness table during the statics calculation. There are two options: Pressurised: the bend moment is calculated from the curvature by simple interpolation of the bend stiffness table. This is the same as the nonlinear elastic model during statics. Depressurised: the bend stiffness is … difference between unhappy and sad
