(deformation per unit length). The basic mechanical properties of wood are obtained from laboratory tests of small, straight-grained, clear wood samples free of natural growth characteristics that reduce strength. Although not representative of the Shear modulus. G. Shear modulus relates shear stress to shear strain. The three shear moduli for wood are denoted GLR, GLT and GRT for the longitudinal-radial, longitu- dinal-tangential, and radial-tangential planes, respectively. 【Get Price】

Modulus of elasticity in composite beam design - ETABS

6 Jul 2012 What are Ec (S), Ec (D), and Ec (V) in composite beam design? Answer: Values for Ec (S), Ec (D), and Ec (V) are given as follows: Ec (S) is the modulus of elasticity for strength design. for LRFD, Ec (S) is taken directly as the modulus of elasticity of the material assigned to the composite section. for ASD, Ec (S) is calculated as 33 * gammac<sup>1.5</sup> * √f 'c (ksi), where gammac is the weight per unit volume (kips/in<sup>3</sup>) of the material assigned to the composite section. 【Get Price】
