The upcoming analysis will encompass both geometric and material nonlinearity. It also offers real-time tracking of the load-displacement curve, enabling an in-depth investigation of the member’s capacity while optimizing computational time. The results will provide insights into the member’s capacity, its deformed state, and its failure status.

Go to the ‘Main Parts’ menu and select the ‘PROFILE’ tab. To input the sections’ geometry, import a DXF file stored locally on your PC. The DXF file can be received from εδώ
Navigate to the ‘SCHEME’ αυτί. When you click on the ‘Updated plate t’ column cell, a popup window will appear. In this window, update the thickness for all edges to t=0 mm.
Add diaphragms to the sections, selecting the ‘Polygon’ τύπος. The edges for the diaphragm are defined in a popup window that appears when you click on the ‘Diaphragm Edges’ column cell. In the ‘DIAPHRAGM INPUT’, select the edges that form the diaphragm shape and input the thickness (τ).

Βήμα 6. Μη γραμμική ανάλυση
Navigate to the ‘Analysis‘ menu. Select Nonlinear Explicit including geometry and material nonlinearity. Click ‘Perform Analysis’ button.
While the analysis is in progress, navigate to ‘Chart’ menu. Πρώτα, select a node to measure the Uy displacement (βήματα 1 και 2). Τότε, using frame selection, choose nodes from which to extract the Ry reaction forces (βήματα 3 και 4). Monitor the chart’s changes to identify the critical force (Pcr) that leads the structure to failure. Terminate the ongoing analysis once the failure state is detected.
