Stiffened base plate design software

Application of stiffeners in the design and construction of steel column base connections is unavoidable. Design of stiffened base plates is necessary when heavy or eccentric loads should be transferred from column to the foundation. In this tutorial, assignment of stiffeners to the column base connection is explained.

Figure 1, Start Session Form. In the New Model Initialization form Figure 2do these steps:. Figure 2, New Model Initialization Form. In the main window of the software, click Stiffener Tab According to Figure 3.

Figure 3, Program Main Window. In the Stiffener tab, select Stiffeners Material. In the next step, Stiffeners Height could be changed.

In this version of the software, height of all stiffeners is equal and can't be different. Figure 4, Stiffener Tab. In the Assign Typical Stiffeners form Figure 5the thickness of the stiffeners could be assigned.

As mentioned above for the stiffener height, the thickness of all stiffeners should be equal and definition of stiffeners with different thickness is not performed in the current version. For any type of column section with the consideration of column position on the base plate, the program suggests the available arrangement of stiffeners. For example in Figure 5, there are six arrangements for the stiffeners. Select any case and then click OK. If the new stiffeners conflict with the defined anchor bolts, below message, will appear.

By clicking Delete Illegal Anchors, the illegal anchors will be removed and base plate model will update for the new stiffeners and legal anchor bolts. Run the analysis Press F5. Latest Tutorials.

Stability Analysis. Eurocode 3. This article provides information which can be used for the design of stiffened buckling panels. Generally, there are two options for determining buckling values of stiffened buckling panels. First, you can obtain the values directly from diagrams by using the existing boundary conditions in accordance with [2] and [3]or second, you can perform an eigenvalue calculation.

The eigenvalue calculation determines critical load factors for the respective existing stress. Evaluation of the determined mode shapes is essential for the design.

The buckling analysis should be performed for the stiffened panel and the corresponding buckling mode will display the global failure mode.

The following example shows the first mode shape for the subpanel buckling above and below the longitudinal stiffener. Figure 01 - Local Buckling. The following figure shows Buckling Mode No. Figure 02 - Global Buckling. Based on the design of stiffened plate and by using the corresponding global mode shape, the calculation of the critical plate buckling stresses according to [1]Annex A, can be performed using the buckling values and the critical buckling stress.

As an alternative, there are the analytical formulas for the calculation of critical plate buckling stress provided in [1], Annex A. However, the following boundary conditions should be applied when using these formulas:. The calculation method for one or two longitudinal stiffeners in the compression zone is based on the elastically supported equivalent member. The critical buckling stresses determined by extrapolation to the compression edge result in the critical plate buckling stresses.

Figure 03 - Example Structure. As previously mentioned, the first mode shape displays the local buckling mode and therefore is not governing for the design of stiffened plate.

In this case, you can now explore an alternative design process. Figure 04 - Design Local Buckling Panel. In the following example, the governing mode shape Mode No. Figure 05 - Design Global Buckling Panel. It should be noted that as an alternative to Option 2, you can perform the analysis using the analytical calculation method for determining critical buckling and plate buckling stresses as described in Annex A.Note: No Protection Password.
