In UC-1/FRAME(In-Plane), it was necessary to create an extra intermediate node and apply a node moment load. This is not required in Engineer's Studio® 2D.

Nodes for load are not required any more because moment load can be input to distributed spring material in the Engineer's Studio® 2D.

1. Cross-section creation

UC-1/FRAME(In-Plane)	Engineer's Studio® 2D
Enter the cross-sectional area and the second moment of area.	Enter the cross-sectional area and the second moment of area. Specify materials. The auto-generation of dead loads is available by checking "Add section area x unit weight"

2. Node input

UC-1/FRAME(In-Plane)	Engineer's Studio® 2D
Enter coordinate values for all nodes.	Enter only the main nodes. Auto-generation of the middle nodes is more easily achieved by dividing beam elements after creating them later. At that time the individual member lengths can be controlled.

3. Member creation

UC-1/FRAME(In-Plane)	Engineer's Studio® 2D
Create line elements by specifying two nodes in the table editor after setting up all nodes. Assign section references to all members.	Select sections, click prepared nodes, and create beams like drawing frames. Possible to undo during commands.

4. Support condition setting

UC-1/FRAME(In-Plane)	Engineer's Studio® 2D
Enter node numbers to set supporting point condition and supporting point code. Not possible to process collective setting for multiple nodes.	Select nodes to set supporting condition by clicking on them and select restraint conditions. Possible to apply the same conditions simultaneously to a set of selected nodes.

5. Load value input

UC-1/FRAME(In-Plane)	Engineer's Studio® 2D
Enter load code, intended members, and load values. Require retyping the load value after recalculating the load value at that position when the middle node is inserted.	Remembering load codes is not required. Select the load type from a list of names such as "point load" and "distributed load" and specify its direction and magnitude. Auto-interpolation of trapezoidal distributed loads is done when an element is split.

6. Data change, edit
Ex) Insertion of intermediate beam (1/4 height above the deck slab)

UC-1/FRAME(In-Plane)	Engineer's Studio® 2D
Create a node at the 1/4 position from the deck slab. Reconnect i and j nodes. Calculate a load value at a newly added node (1/4 position) and setup.	Divide sidewall elements using the "divide members" function. Connect the left and right intermediate nodes that are automatically generated by the division process using your mouse. The intermediate load value of the trapezoidal distributed load acting on the side wall is automatically interpolated.

*1: Only corner node coordinates were entered. The remaining middle nodes were entered when creating the elements.
*2: Values in the table represent seconds.

The model used in the above comparison is the BOX Culvert in-plane analysis shown in the picture on the right.
The self weight load case, 2 other load cases and combined cases of those are input.
Section properties and load value calculations are done outside the times quoted here. However note that the self weight load case is automatically calculated in Engineer's Studio 2D. Only the time of data entry and editing was compared.
The application operators used in this comparison have more than 5 years experience in this area.

The percentage improvement in usage times is shown in the graph on the right.
The larger the model is, the greater the time difference becomes.

Time is cost and so especially for larger models, the cost saving achieved by using Engineer's Studio 2D compared to UC-1/FRAME (in-plane) is great.

This is especially noticeable when editing the model.
