Abstract

This article presents application examples of nonlinear advanced supports. The purpose is to highlight how these supports work and the different mechanisms they have.

Keywords: Advance Design, Advanced Supports, Nonlinear Analysis.

1.Introduction

Some structures require special type of supports such as:

  • Supports that work only in tension or compression (tension or compression only supports).
  • Supports that allow displacements/rotations within specified limits. Once these limits are reached, the supports are activated and no further displacements/rotations are allowed (gap supports).
  • Supports that block displacements/rotations until specified reaction forces/moments limits are reached. Once these limits are reached, displacements/rotations are allowed while maintaining the limit forces/moments reactions (hardening supports).

Advance Design has all these special supports available in the advanced supports feature. They can be assigned to each DOF separately and are available for point, line and surface supports (refer to Figures 1 and 2)

In addition to these supports, a user defined nonlinear support mechanism is also possible (“NL-Diagram” option in Figure 2).

2.     Application examples

1.1.            Gap supports

Two identical 2D frame structures are considered. A pin support is used on the left side and an advanced support on the right side for each frame (refer to Figure 3). Frame 2 carries double the load of frame 1.

The advanced support for both frames is fixed in the vertical translation and presents a 2 cm displacement gap in the horizontal translation (refer to Figure 4).

Since nonlinear supports are used, a nonlinear analysis is conducted and the results are presented in Figures 5 and 6:

In Figures 5 and 6, it is clear that for frame 1 the gap support did not reach its limit (1.67 cm < 2 cm) therefore no horizontal support force was applied to block the displacement. For frame 2, theoretically we should get twice the displacement since it carries double the load. However, the gap limit of 2 cm is reached and a horizontal support force is applied to block any further displacement.

2.2.            Hardening supports

Considering similar frame structures to paragraph 2.1. A pin support is used on the left side and an advanced support on the right side for each frame (refer to Figure 7). Frame 2 carries double the load of frame 1.

The advanced support for both frames is fixed in the vertical translation and presents a 10 kN limit hardening support in the horizontal direction (refer to Figure 8).

Since nonlinear supports are used, a nonlinear analysis is conducted and the results are presented in Figures 9 and 10:

In Figures 9 and 10, it is clear that for frame 1 the hardening support limit is not reached (8.27 kN < 10 kN) therefore the support was able to block the displacement. For frame 2, theoretically we should get twice the support force since it carries double the load. However, the hardening support limit of 10 kN is reached and it can no longer block any further displacement requiring more than 10 kN of force.

3.     Conclusion

The advanced supports are a powerful tool in Advance Design for modeling structures with particular support conditions. The user can choose between predefined support mechanisms such as gap and hardening supports or define his own mechanisms.

Transfer beam analysis using construction stages

/ graitecgroup / Leave a comment

by Naim AYOUB
Product technical specialist

Abstract

This article highlights the importance of construction stages in studying frame structures with transfer beams. For this purpose, a result comparison between Advance Design construction stages and classical full model single run analysis are presented for a steel frame model with a transfer beam.

Keywords: Advance Design, Construction Stages, Transfer Beam.

1. Introduction

In conventional structural analysis, all loadings are applied at once on the complete final structure before studying their effects in a single step calculation. In other words, no loading of any type is applied on the structure until the entire construction process is completed. However, in practice, structures are constructed in stages (story by story) and loadings such as self-weight, construction and finishing loads are present at each stage prior to structure completion. Therefore, at each construction stage, the distribution of displacements and internal forces in the completed parts of the structure (due to the existing loads) is not affected by elements of upper stories that do not exist yet.

Neglecting the construction stages effect in the classical analysis will sometimes yield wrong results.  A good example where this effect should not be overlooked is in analyzing frame structures with transfer beams.

2.Frame structure with transfer beam

A steel frame structure with a transfer beam in story 1 is considered. This structure is subjected to its self-weight and finishing dead loads at each story (refer to Figure 1).

2.1.            Construction stages

Construction stages are defined according to the actual story by story construction sequence (Refer to Figure 2).

2.2.            Results comparison

To highlight the importance of conducting construction stages analysis, results comparison between the Advance Design classical analysis (all loads applied at once on the complete final structure) and construction stages will be presented (refer to Figures 3, 4 and 5).

3.     Conclusion

The real structural behavior obtained by the construction stages analysis is very different from the results of the classical analysis. Neglecting the construction stages effect, will lead to a dangerous under dimensioning of the transfer beam and middle column.

How to find out the start point and direction a beam was created in advance Steel 2018

/ graitecgroup / Leave a comment

While searching the forum, I found an intriguing question and I thought I would create a short video to address the issue.

Here is the dilemma, you are working on many projects simultaneously. While jumping from one project to another, you notice that in some of the drawings, your beam orientation is not as you expected.

It would be great if, in the steel structure, you were able to find out the start point of the beam. Did you create the beam from left from right or right from left?

TIP: Advance Steel allows you to view what direction the beam was created.

Open the Advance Steel Tool Palette and select the UCS category, which is the fourth icon in the first column.  Within that category select the second icon called “Define coordinate system” in the third row.

After selecting the beam in question, you will find a symbol as seen in Figure1. The symbol shows you that this beam was created from right to left and in Figure 2 the beam was created from left to right.

How to have Advance Steel 2018 recognize and use a customized Prototype that was created in the default location

/ graitecgroup / 1 Comment

Woah, I’m using the American installation of Advance Steel 2018. I’ve opened the Prototypes folder located in C/ProgramData/Autodesk/Advance Steel 2018/USA/shared/Support/Prototypes.

I copied an existing prototype and created a custom Prototype (Title block), for my company and saved it in this default location of Advance Steel.

I create drawings and Advance steel is using the Prototype, aka Title blocks from the default setup not my customized Prototypes. I get a warning that says “Prototype not found.”

How can I have Advance Steel recognize my custom Prototype?

Advance steel is able to recognize you custom prototype, however you need to map it to the correct Drawing process.

Please watch the video to view the steps to have Advance Steel 2018 recognize and use a customized Prototype that was created in the default location.

How to create a BOM of selected elements using the model browser Queries option in Advance Steel 2018

A civil view from your seat

/ graitecgroup / Leave a comment

During the ‘suites’ era, many companies upgraded from a single license of Civil 3D, or another vertical product, because the upgrade was offered for free. However, not many used the products offered in the suites.

Now that 2016 has come and gone, and so have the suites, we now have the Autodesk Collections. These Collections offer much more than the suites did.

This article will take you through a workflow for using your collection (or suite), to bring your Civil project from a bland, 2-dimensional visual to a realistic 3D animated model. You will need a good understanding of InfraWorks and Civil 3D in order to follow these instructions.

The software used for this workflow is Civil 3D, InfraWorks and Civil View, which is a plug-in inside of 3ds Max. You don’t have to be a 3ds Max expert to do this. You don’t even need to know how to use 3ds Max at all.

How to create a handrail to an existing stair and anchor it to a concrete wall using the wall rail tool in Advance Steel 2018

/ graitecgroup / Leave a comment

With Advance Steel 2018, you can now create a wall rail on concrete.

The wall rail tool is located on the Extended Modeling tab, Structural Elements panel. This video will show how to accomplish this.

Simply move the UCS to the face of the concrete, position the orientation of the X and Y axis accordingly, use the view on UCS tool and turn on your 2d snaps located on the Quick views category of the Advance steel tool Palette.

Create a line where you want the wall rail to be. In this video the system line of the stringer and landing was used.

Use the wall rail tool to create and customize the rail. Tweak the railing using the options located on the General, Wall Plates, Connections and Rail Segments panels. You can then save the customized railing in the library located on the Properties panel for later use.

How to change the slope dimensions to display in inches or only degree

/ graitecgroup / Leave a comment

Here is the issue, you have created a drawing which have sloped dimensions on it. You want the dimensions to display in inches rather than feet. Perhaps you have a client that wants to have the slope dimensions displayed in degrees rather than inches. How do you accomplish this in Advance steel?

This can be done locally on each drawing sheet, however, what if you have the same scenario on hundreds of sheets?

Not to worry. You can make the changes globally and have the changes reflect the created sheets after updating the database and using the force Update for the drawing or by updating the drawing in question.

How to change the piece marks that have an incorrect Phase number

/ graitecgroup / Leave a comment

Here is the dilemma, you have created a structure in phases and notice that some elements of the structure don’t reflect the phase. In fact, the piece marks are displaying the wrong phase number in the Model browser and the drawings they were created on.

What do you do, certainly not renumber the entire structure?

Advance steel allows you to remove the numbering and information from the problematic elements using the Toggle switch display SP/MP tool located on the Output tab, Part marks panel.
