i have got into trouble with linear gap element. My model like flange contact have 500000 dof. i use linear gap method in axial direction and rbe2 (Fy~Mz) in other direction. unfurtunately, i just obtain some fatal message "fatal message 1012" no matter what i do.

MVPs.In linear analysis, starting from displacements, the nodal forces can be calculated in two equivalent ways: a) R_e = K_e * U_e. b) At each integration point, calculate strains using B (m) * U_e, calculate stresses using C*e, then integrate stresses using Eq. 4.29. R_e: element nodal force.1) Perforated. There are code restrictions on why you can use this.

Obviously if the supports were t0 be removed the pipe stack would collapse. It follows that there is a horizontal component of the load at ...

Hot dip galvanized anchor bolts should be used if corrosion is a concern. Do not have regular black anchor rods galvanized, since the clearances would not be correct. As stated above, you can also coat the exposed portions with grease, paint, gooey-anti-corrosion-stuff, or whatever after fastening, but not before.

The saving grace is that even when you use one of the methods above, in the great scheme of things it makes little difference. RE: Extracting bolt loads from cbush elements. …Efficiency (measured in stiffness or strength per unit of weight) is not highest with compact sections - it is actually quite the opposite. Class 3 sections, for example, rarely require transverse or longitudinal stiffeners, but the larger web depth acquired with them far offsets any issues relating to elastic section capacity or local buckling.Join Eng-Tips ® Today!
