I am getting a WARNING: IN UNIFORM MEMBER LOAD. ITEM "f3" NOT PROVIDED FOR MEMBER 2 CASE 1

             "f3" ASSUMED TO BE MEMBER LENGTH =   12.00 . What does the warning mean ?

 

When one specifies uniform member load on a member, the software expects the data to be according to the following format

 

MEMBER LOAD

member-list { { UNI | UMOM } dir-spec f₁ f₂ f₃ f₄

 

where f1=magnitude of load

f2 =distance of start of uniform load from start node of member

f3=distance of end of uniform load from start node of member

f4=perpendicular distance from shear center to plane of loading

 

If f2 and f3 are omitted, the member load is applied for the full length of the member. However if f2 is provided but f3 is not provided, then a warning message like the one mentioned, appears in the analysis output file. In such cases the software assumes a value of f3 to be the full length of the member and the loading is applied from f2 to the end of the member. So if the entire length of the member needs to be loaded, simply specify f1 and leave out both f2 and f3. Else if the member is partially loaded, one may use both f2 and f3.
