Specifying the parameters

Now, let’s open the Parameters manager and define the following parameters:

Parameter	Type	Value
span 1	Length	6
span 2	Length	12
span 3	Length	18
load – total	Line load	-1000
load – outer beg	Line load	-1000
load – outer end	Line load	-1000
load – inner beg	Line load	-1000
load – inner end	Line load	-1000

Let’s close the Parameters manager and select the end node of the first span.

In the Property window let’s select item GCS coordinates > Coord X and change its content to "span 1" (Using the little down-arrow button).

Similarly, let’s change the X co-ordinates of end nodes for the second and third span. Let’s change their values to "span 2" and "span 3" respectively.

Now, let’s adjust the second load case to be displayed in the window. Select all the loads and let’s focus on the Property window again. Let’s change the load value to parameter "load – total".

Further, let’s adjust the third load case to be displayed in the window. Select all the loads and let’s focus on the Property window again. First let’s change the Distribution to Trapez. Then, let’s change the load value 1 and value 2 to parameters "load – outer beg" and "load – outer end" respectively.

Similarly, let’s make the same change with the load in the last load case. Here, let’s use the parameters "load – inner beg" and "load – inner beg".
