CHAP 4 Finite Element Analysis for Beams and Frames 239 18. A linearly varying distributed load is applied to the beam finite element of length L . The maximum value of the load at the right side is q 0 . Calculate “work equivalent” nodal forces and couples. Solution: The distributed load is a linear function. 00 () x q x q sq L     Thus, the expression of distributed load can be written as 34 1 2 3 4 1 1 0 2 2 32 9 ( 2 ) 2 { } [ ] 21 60 3 L T s s s F M L s s s L qL x q dx q Lds F L ss ML L s s 
