BAB VIBAB VIPERHITUNGAN SAP

Secara konvensional dalam mencari gaya-gaya batang di dalam sistem portal dapat diselesaikan dengan metode cleperon, metode slope deflection, metode cross, metode energi, dan lain-lain. Tetapi juga dapat digunakan metode matriks kekakuan yang disebut juga dengan metode displacement (metode perpindahan).

Matriks kekakuan terhadap Sumbu lokalSetiap elemen memiliki sumbu lokal masing-masing

Hubungan antara gaya dengan perpindahan adalah :{ fe } = [ k ] { d }dimana :{ fe }=gaya[ k ]=matriks kekakuan{ d }=perpindahan

{ fe }=SX1{ d }=u1SY1v1MZ1dan1SX2u2SY2v2MZ22

Sedangkan matriks kekakuan adalah sebagai berikut :[ k ]=E A00- E A00=LL012 E I6 E I0- 12 E I6 E IL3L2L3L206 E I4 E I0- 6 E I4 E Ik11k12L2LL2L- E A00E A00k21k22LL0- 12 E I- 6 E I012 E I- 6 E IL3L2L3L206 E I4 E I0- 6 E I4 E IL2LL2LMatriks kekakuan terhadap Sumbu global

Untuk simpul 1f1=SX1=cos - sin 0SX1SY1sin cos 0SY1MZ1001MZ1=[ T ]{ f1 } (1)Untuk simpul 2 berlaku juga seperti simpul 1Dengan demikian maka untuk satu elemen berlaku :{ fe } = [ Te ] { fe }

Te=[T0]0T (2)Untuk displacement vektor{ de } = [ Te ] { de } (3)Dari persamaan (1), (2), dan (3)[ Te ]-1 { fe } = [ ke ] [ Te ]-1 { de }{ fe } = [ Te ] [ ke ] [ Te ]-1 { de } = [ ke ] { de }dimana :[ ke ]=[ Te ][ ke ][ Te ]-1=[ Te ][ ke ][ Te ]Tketerangan :[ Te ]-1=[ Te ]T==>karena [ Te ] adalah matriks ortogonal

Maka untuk batang miring

dengan :s=sin c=cos Degree Of Freedom (DOF)Joint atau nodal memiliki peranan penting pada pemodelan analisa struktur. Nodal merupakan titik dimana elemen-elemen batang bertemu sehingga mempunyai bentuk yang bermakna yaitu geometri struktur itu sendiri.

Degree of freedom (DOF) adalah derajat kebebasan suatu titik nodal untuk mengalami deformasi yang dapat berupa translasi (perpindahan) maupun rotasi terhadap tiga sumbu ruang.

Jadi untuk suatu nodal dapat terjadi 6 bentuk deformasi jika berada pada suatu kondisi bebas yakni 3 translasi (x, y, z) dan 3 rotasi (x, y, z). Suatu nodal tidak bebas berdeformasi (tertahan) karena diberi restraint atau disebut juga sebagai tumpuan.
