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 GY –
MEMBER LOAD
member-list { { UNI | UMOM } dir-spec f1 f2 f3 f4
where f1=magnitude of load
f2 =distance of start of load from start node of member
f3=distance of end of load from start node of member
f4=perpendicular distance from shear center to plane of loading
when f2 and f3 are omitted, then 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 accordingly. 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.
