	1.75	Stepped beam
	2.00	Stepped beam

Position of stepped-up segment

Select position of stepped-up segment
(When k is larger than 1.00, the selected item will be considered)

Choices	Case	Location
	Left end
	Center
	Both ends
	Right end

Length of the stepped-up segment of the beam

(When k is larger than 1.00, the selected length of stepped-up segment below will be considered)
(When having 2 stepped-up segments, the selected length is the sum of them)

Loading on beam

Multiple loads (max. 2 point, +2 UDL, and +2 bending loads) can be superposed on this beam.

Key diagram for point loads

Input data for 0-2 point loads:

		#1	#2	← check/uncheck to enable/disable load(s)
Point load (kN)	P =	+\|– 10.0	+\|– 10.0	← check to signify negative value of P ← slide to get the desired value of P ← current value of P (kN)
Distance from left (m)	a =	0.5	1.0	← slide to get the desired value of a ← current value of a (m); a ≤ L

Key diagram for UDLs

Input data for 0-2 distributed loads:

		#1	#2	← check/uncheck to enable/disable load(s)
Uniformly distributed load (kN/m)	q =	+\|–	+\|–	← check to signify negative value of q
Left unfilled distance (m)	a =			← Condition: (a+b) < L
Right unfilled distance (m)	b =			← Condition: (a+b) < L

Key diagram for bending moments

Input data for 0-2 bending moment loads:

		#1	#2	← check/uncheck to enable/disable load(s)
Bending moment load (kN.m)	M =	+\|–	+\|–	← check to signify negative value of M ← select a value for M
Distance from left (m)	a =			← Condition: a ≤ L
