Next we will create beams at the view +13400 level.
By using the same beam properties that we applied earlier, create the missing beams at the gridline intersections shown in the figure below.

Next we will create beams in locations where no gridlines intersect. The snapping tools help you pick points to position objects precisely without having to know the coordinates or layout additional lines or points.
Create the rest of the beams
Help: Modeling > Settings and tools > Tools > Snapping
1. Double-click one of the existing beams in the model and press Apply. Create beam A
2. Start the beam command. 2. Start the concrete beam command.

3. Make sure only the Snapto reference lines / points icon of the two main snap switches on the right is pressed down.
4. Make sure theSnap to mid points and Snap to end points icons are pressed down.
5. Pick a midpoint of the beam between A-2 and A-3 and then the midpoint of the beam between B-2 and B-3.
5. Pick a midpoint of the beam between A-2 and A-3 and then the midpoint of the beam between B-2 and B-3.
We will pick the start position of beam B by using the gridline intersection A-1 as a temporary reference point and tracking along gridline 1 in the direction of intersection B-1 for 9000 mm.
Create beam B
We will then pick the second position of beam B using the temporary snap switch Perpendicular.
1. Start the beam command. 1. Start the concrete beam command.
Pick the first position of beam B
2. Hold down theCtrl key and pick gridline intersection A-1 as the origin to show the
“From” location coordinates.
3. Then use the cursor to snap (do not pick!!) in the correct direction (e.g. to gridline intersection B-1).

4. Type 9000 for the numeric location. (TheEnter a numeric location dialog box will open automatically.)
5. Press OK orEnter and the cursor snaps to the correct position. (=9000 mm from A-1 in the direction of B-1).
6. Right click and selectPerpendicular. Pick second
position of beam B
7. Pick the second position on beamA (see below).
7. Pick the second position on beamA (see below).

While still in the beam command, Create beam C
8. Right click and selectIntersection for snap override.
9. Pick the intersection of beam B and gridline 2 and then the intersection of gridlines B-2.
9. Pick the intersection of beam B and gridline 2 and then the intersection of gridlines B-2.
We will first create one of the beams that frame around the silo and then by using theCopy >
Rotate command create the other three.
Create beam D

1. Hold down theCtrl key and pick gridline intersection A-1 to show the “From” location coordinates, use the cursor to snap (do not pick!!) in the correct direction. (E.g. grid intersection B-1).
2. Type 4000 for the numeric location and pressEnter, the cursor snaps to the correct position.
3. Type the letter O on the keyboard to snap to positions in orthogonal directions on the work plane (0, 45, 90, 135, and 180 degrees).
4. Let the cursor snap to the midpoint as shown below and pick.
5. Type the letter O to turn the ortho off.
1. Select the beam that you just created.
Copy rotate the
beam 2. Right click and selectCopy special > Rotate… from the pop-up menu.

3. Pick the center point of the silo as the point to define the rotation (select a view in which the silos are visible and pick near the circumference to snap to the center point). The origin X0 and Y0 values will appear in the dialog box.
4. Complete the other fields in the dialog.
5. ClickCopy.
We will now copy the beams to the other silo.
Copy translate the beam to the other
silo 1. Select the beams shown highlighted in the picture below (press theCtrl key to add parts to the selection).
2. Copy special > translate… them 9000 mm in the x direction.
Bracing
Working in theGrid A elevation view, we will input the vertical steel bracing members using theCreate beam tool.

1. Double-click on theCreate beam icon.
Create braces a and b
2. Complete theBeam properties dialog box as shown below andApply.

3. In the 3d view create brace a by first picking the gridline intersection A-2 and then the midpoint of column A-3.

4. Create brace b by picking the top position of column A-2 and then midpoint of column A-3.
We can see from the drawing above that the lower end of the brace needs 200 mm offsetting from the grid level. Now we will use handles to move the part end.
Use handle to move brace end

2. Select the yellow handle (Tekla Structures then highlights the handle).
3. Right click and selectMove special > Translate… to move the handle 200 mm upwards.
4. ClickMove.
5. Repeat the procedure to move brace b’s top handle 1000 mm downwards.
1. Select braces a and b.
Copy mirror braces a and b
2. Right click and selectCopy special > Mirror…
3. In the 3d view, pick grid A-3 then grid B-3 to define the mirror line.
4. ClickCopy.

Now we have modeled all the steel and concrete members in Model1. The model should look like in the picture below.
