ALGORITMA OPERASI TEKUK KOLOM

1. Algoritma Program Tekuk Kolom

a. Algoritma cara hitung langsung

1. Memulai

Menjalankan program

2. Memilih perletakan

Membaca data pilihan yang telah dimasukkan:

2.1 sendi - sendi

2.2 sendi – jepit

2.3 jepit – jepit

2.4 jepit - bebas

3. Memilih penampang

3.1 penampang T

3.2 penampang L

4. Memilih jenis bahan penampang

4.1 bahan baja = 120000 mpa

4.2 bahan alumunium = 200000 mpa

4.3 bahan beton = 20000 mpa

4.4 bahan lainnya (memasukan data sendiri)

5. Memilih panjang batang

L

6. Memasukan nilai dimensi a,b,c,d (milimeter)

a b

c a

b

d c d

7. Tampilkan hasil perhitungan

7.1 Ix kanan-kiri

7.2 Iy atas – bawah

7.3 Pmax

7.4 P diperbolehkan

8. Selesai
