Given: The Felton problem 4-29 frame modified as shown below.

Use L = 3 ft, P1 = 10 kips, q0 = 1 kip/ft, q1 = 2 kips/ft, E = 29,000 ksi, I = 1000 in⁴.

This is a modification of the previous problem, so we will bring it back up and modify it.

Note that this looks very much looks very much like our present problem, except we will have to add some loads, and add a pin at the end of member M1. Also, the supports have changed.

Change the support at node 3. You can click on the node to highlight it before starting the modification (looks like a black box around the node). This will pre-select that member (node) before entering the edit mode. Then click on the Edit Selected Member button. Note that at this time there is only one horizontal reaction shown on Node 3.

Go into the Edit mode and change the support from a roller to a pin:

Now note that there are two reactions at node 3. Also, you can see that I used the "View, View Manager" to change the screen display. It now shows the node names, and other clutter has been removed. I should have done that before I started.

Now, change Node 1 from a pin to a fixed support:

Now we will add Hinge B. Note that Hinge B is located at the end of member 1, NOT at the joint. Thus this pin would release any moment capacity FROM THE END OF MEMBER 1 INTO THE JOINT. If there were actually a pin AT THE JOINT, you would have to put a second pin, for example, at the end of member 2 OR at the beginning of member 3. You COULD NOT put three pins, one at the end of member 1, one at the end of member 2 and one at the beginning of member 3! This would leave the joint at Node 2 unstable in the moment direction.

Thus, click on member 1 to pre-select it:

Now go to "connections." Not only can you change all kind of member information, you can even change the nodes to which the member is attached. Here I have released the strong moment at the N2 node end of the member.

Now note that there is a pin at the end of member 1 (the slanted member.)

Next we will edit the loads on member 2, from node 3 to node 2. Click on it to pre-select it.

The "General" tab tells you which load case you are working with. The source tab would let you specify whether the new load is a "dead" or a "live" load, or whatever. We are just using dead loads for everything, so there is no need to click this tab.

Now add a load by clicking on the "Loads" tab, then on the "New" button. Note that members M3 and M4 already have loads on them, marked "DY." This means that the loads thus noted are in the "Global" Y direction, i.e. they are oriented with respect to the "earth's" y axis, as opposed to the member's own personal y axis (perpendicular to the length of the member.)

Now the "Create New Member Load(s)" box appears. Click on the "Type" tab, and the "Linearly distributed" radio button.

I then clicked on "OK" and got the screen shown below. Reason? I forgot to fill in the loads on the member. So click OK to get rid of the error box, and enter the loads.

Click on the "Magnitude" tab, and enter the loads. Also, "unclick" the "Full member length" check box, since you don't want the loads to go over the entire member. You only want the loads to cover one half of the member length, and since the member is 12 feet long the load starts at 6 and ends at 12 feet. Then click OK.

Now click on the "Edit Service" button to add a "projected" load onto member 1. Pre-select the member if you wish (click on it to highlight it).

Click on the "New" button.

On the "New Load on Member: M1: box, you will have to check "Global direction" (i.e. use the earth's y axis for the direction of the load), "Uniformly distributed" (NOT Linearly distributed, since both ends of the distributed load are of the same magnitude), and also check "On projected member length." This will put the load on the member as shown on the original problem statement. Note that when the program draws the load on the member, it looks the same whether you check "On projected member length" or not. You just have to have faith that the loads on a "projected" member are smaller that loads on a "non-projected: member. However, I have checked it carefully, and assure you it is correct.

Now click the "Magnitude" tab.

Enter the loads. Note here that because I erroneously entered the load as "Linearly distributed" rather than "Uniformly distributed", I am going to have to enter the same value twice, one on each end of the member.

Finally, the structure looks as follows. Note that the load on member M1 says "-2 K/ft (Proj.) i.e. projected. That will give it a total of 2 K/ft * 6 ft = 12 kips, rather than a total of 2 K/ft * 10 ft = 20 kips, which would be the case if you did not see "Proj." on the load.

Now put the concentrated load on member m1. State its type, and note that the direction of the load is not in the global y direction, but rather perpendicular to the member's axis! Thus, click on "Single, concentrated", and "Local direction" (i.e. local member direction.) The load is transverse to the axis of the member, so it is a shear y direction load.

Then enter the magnitude, and location from the START of the member to the load (the offset from the node.) The start of our member was at node 1.

And finally, add the top uniform load to member M1. Under "Type" enter "Uniformly distributed", "Local direction" since the load is normal to the local member axis, and "Direction = Shear y."

Under "Magnitude" enter -2 K/ft, Start at 15 ft and End at 20 ft.

When you hit the "Enter" key, you will get a summary of the loads you have placed on the structure. Note that Member M1 has several forces on it, some noted DY and others noted dy. The DY means with respect to the global (earth) y axis. The dy means directed along (or perpendicular) to the local member axis. Also, forces that are "Projected" on the member are also noted.

Finally, a view of the entire structure:

After running the program, it shows you the deflected structure. Forces and other information can be obtained as before.

NOTE that if you don't get the member internal forces, or something else like that it is because you did not include them in your report request. Hit "Options", "Edit Report Style", highlight the "Basic Model Report Style" and click on the "Edit Style" button, then highlight "Member Extreme Results" or whatever you are missing, and add it to the right hand window for "Reported Items."
