algorithmic modeling for Rhino
Am attempting to simulate a glulam structure for a project we have in school...
Specifically the product we're working with is
GL32h HASSLACHER NORICA TIMBER
E (Number) Young's Modulus [kN/cm2] of the material :1370.0
G (Number) Shear Modulus [kN/cm2] of the material : 85.0
gamma (Number) Specific weight [kN/m3] of material : 4.2183
alphaT (Number) Coefficient of thermal expansion [1/C°] of the material: -
fy (Number) Yield strength [kN/cm2] of the material.
Have input these values into Karamba but however a singular stiffness matrix error is returned from the Analyse THI & THII components. I understand that this is due to the G value having to be between E/2 and E/3. Is there however any way to get around this though? To simulate the actual characteristics as closely as possible
at the moment (version 1.2.2) there is this limitation for the transverse shear stiffness you mention. In version 1.3.0 this limitation will be lifted.
The shear stiffness influences the results only in case of very compact beams.
