Contoh Perhitungan Perencanaan Awal Dimensi Balok Teknik Sipil

Denah Perencanaan Awal Dimensi Struktur

Menurut SNI 2847 pasal 11.5 bahwasanya untuk ukuran balok di tentukan bahwa tinggi balok minimum berkisar antara 1/8 bentang s/d 1/21 bentang.

            Balok induk memanjang ( L = 8000 mm)

            Tinggi balok (h)          = (1/10 – 1/14) x L

                                                = 1/12 x 8000 mm

                                                = 670 mm = 700 mm

            Lebar balok (b)           = (1/2-2/3) x L

                                                = 1/2 x 700 mm

                                                = 350 mm = 400 mm

Dimensi balok induk memanjang 400/700 mm

            Balok induk melintang ( L = 5000 mm)

            Tinggi balok (h)          = (1/10 – 1/14) x L

                                                = 1/10 x 5000 mm

                                                = 500 mm

            Lebar balok (b)           = (1/2-2/3) x L

                                                = 1/2 x 500 mm

                                                = 250 mm % 300 mm

Dimensi balok induk melintang 300/600 mm

Balok anak melintang ( L = 5000 mm)

            Tinggi balok (h)          = (1/10 – 1/14) x L

                                                = 1/10 x 5000 mm

                                                = 500 mm

            Lebar balok (b)           = (1/2-2/3) x L

                                                = 1/2 x 500 mm

                                                = 250 mm % 300 mm

Dimensi balok anak melintang 300/500 mm
