Have you ever stopped for a second and thought, “do we ever validate our rigid plate assumption when designing anchorage to concrete?” The answer is simple. There is no analytical method for validation and, because the design codes mandate it, the design engineer abides by it as it is a Building and Safety (Plan … See more A criterion for Non-Rigid Base plate assumption must first be developed. When a design engineer thinks about a non-rigid base plate, what … See more The plastic strain limit depicts the behavior of the plate beyond the yield point. To understand this further, look at the defined material behavior curve. A material behavior curve is typically a stress-strain curve … See more The third parameter, an important one, is the anchor force. In CBFEM, as discussed in the previous article, the fixture, plate, and anchors are modeled as components held together by the mesh. Now, look at the load path through … See more Now the second parameter is examined to see how it can be related to the established criterion. As the plate yields, it deforms, and the CBFEM captures that absolute deformation. … See more WebDec 31, 2024 · 1 Jan 21 14:10. KootK very complete answer as usual. My interpretation of the responses is that base plate bending occurs as a result of column axial compression due to. 1) Errors in construction such as voids in grout, warped plate, etc. 2) Crushing of grout under the center of the base plate.
