The value in this chart represents the test configuration where the notches are machined parallel to the reinforcing mat. For notches machined perpendicular to the reinforcing mat, this value would be two to three times larger. The Shear Modulus value has been determined from tests with full sections of EXTREN structural shapes. (See the Strongwell Design Manual for further information.) Plate compressive stress/modulus measured edgewise and flexural stress/modulus measured flatwise. Values apply to Series 525 and 625. Measured as a percentage maximum by weight. Span to depth ratio of 3:1; EXTREN angles will have a minimum value of 4,000 psi and the I/W shapes are tested in the web. Typical values because these are shape and composite dependent tests. This is a typical value which varies with composite thickness. LW = Lengthwise CW = Crosswise PF = Perpendicular to laminate face N.T. = Not Tested March 2.04 STANDARD RAILINGS: A. Design 1.
