Member Loads
Select the load Type from the dropdown.
a_param: dist from node i [m] (0 = full span for UDL).
Triangular loads act over the full span — a_param is ignored.
UDL acts perpendicular to the member. UDL_along and UDL_horiz act vertically: _along is per metre of member, _horiz per metre of horizontal projection. a_param is the loaded length from node i (0 = full span) — measured along the member for UDL_along, horizontally for UDL_horiz.
