PIPE ANCHORS
Structural I-Beam Anchors
Design Analysis:
Von Mises stress was used
to calculate the safety factor of the anchor with various load requirements. The highest stressed point was the base of the weld at the front edge of the I-Beam.
The Pro/MECHANICA® Finite Element Model was used to determine the high stress areas on the anchor and calculate the safety factor. The model was constrained along the edges of the base plate to simulate the welding of the anchor to the existing structure. This method of constraint was chosen because of the unknown factors in the bolting of the anchor to different structures. All edges of the base plate were constrained in XYZ translation. The model was meshed with "P" elements, which also included the weld geometry.
