jangan lupa selalu nantikan video video
kami terbaru Oke
kita akan belajar cara menghitung hasil
tes kuat untuk beton ya benda uji balok
mungkin yang belum familiar Apa itu kuat
lentur nanti kita bisa lihat di video
ini ya
dimana biasanya untuk water ini untuk
jalannya Kalau istilah kerennya ya FS ya
flekstore Al Strange What lenturnya saat
ini mengadopsi dia STM ya kalo yang
belum tau astm yaitu
American standard charge of material
kalau sini konkret 78 nomornya Hai Di
sini ada c78 dan
c29 ya Sorry 293 yaitu metode tentang
typhoid wedding dan metode centerpoin ya
jadi tes kuat unsur ini ada dua metode
ya yuk nah selama lemas install lanjut
dan saja
kita lihat benda uji balok ya benda uji
balok untuk fakturnya balok Ini ukuran
penampangnya 15k 15 dan panjang balok
minimal 50 cm menit contohnya
penampangnya 15 k15 tebal dan tingginya
dan untuk panjangnya minimal 50 Sentia
Kalau yang ini saya berikan contohnya 60
senthil seperti ini
benda ujinya
Bagaimana cara menghitung menghitung
rumus kuat lentur balok yang jadi
ada dua pengujian yaitu
itu dengan
typoid legging icmje 78
ini seperti ini nanti pengetesan seperti
ini nyanyi benda ujungnya ini B lebar
dirinya Singgih Hani panjangnya gaji 60
cm Nah nipe itu apa bedanya beban
misalnya samponya Kangen ya ini salvin
bisa jadi samponya kg juga bisa atau n
juga bisa B lebar balok lebar sampai
senti dirinya tinggi balok yang diduga
dan Elya iletou panjang perletakan
sabasanti kalau sini sudah debat 45 cm
nih harga mati yang pernah sendiri terus
bagaimana rumusnya menghitung Fortuner
tersebut kini rumusnya capek kali l
dibagi BD kuadrat beban kali l panjang
perletakan Panglima Sandy dibagi A B C
kuadrat yakni bisa madunya ya kembangkan
seperti ini ya ini untuk metode yang
typhoid loading atau dua titik beban ya
kalau ini Rumus yang kedua dengan metode
apa sangat odette beban atau center
point yaitu dia CNC 293 Yani center itu
maksudnya Ya di sini pasti cuma satu ya
kalau tadi kan ada dua ya di sini cuma
satu ya oke tua ini sama
ukuran juga sama terus rumusnya Seperti
apa rumusnya yaitu tiga kali plp2b
dikuadrat ya dek kalau tadi cuma prb di
wajah nih 3 ditambah 3 y tiga kali plp2b
D kuadratnya Jadi kalau kuatur itu ada
dua rumus jadi kita harus tahu dulu mau
pakai metode yang sporty a Hai
guys Friends seperlunya tetap
Hai ini hal-hal yang perlu kita catat
saat pengujian ya yaitu yang pertama dan
berat benda uji kedua dimensi benda uji
pembacaan beban ya terserah kita
sebanyak berapa
penampang bertanya terus kode benda
ujiannya harus tahu Corbuzier siang
eh Deep dites itu apa misalnya Jalan
jalan-jalan
fs45 tanggalnya pemenang tanggal
pembuatan dan tangga pengujian yaitu
harus ada terus setelah itu ya tentu
kita hitung kuat lenturnya ya
Hah Ini contohnya contoh-contoh
pengujian kuadran lentur kuat lentur
resin jangan lupa tekan tempat
ini pertama kita timbang benda Uchiha
strategi kembang kita catat beratnya
berapa crunchy men Nah dengan sih dari
panjang lebar dan tingginya Ah terus
yang ketiga ini kita beri tanda as benda
uji untuk peletakannya ini kita cari Axe
dulu nih setengahnya
ini panjangnya kesini 15 ya 15 dan tidak
dipasang kesini tujuh setengah ini guys
tidur setengah ini yang ujung sama ujung
ini panjang 45 cm tapi sialnya di sini
ya ini lebih muda seperti ini pasti
tengah ya
TNI kita panjangnya totalnya 45 senti ya
terus yaitu masukkan benda uji setelah
itu ya sudah kita gambar kita masukkan
benda uji ke mesin tasnya dan pasang
sesuai peletakannya jantes dengan
kecepatan konstan nya depannya mesin
tasnya itu ada pesertanya Jangan
langsung cepat jadi harus bertahap ya
yang kelima catat hasil beban dan Squad
Nur dan hitung khas daunnya ya
Nah ini contohnya setelah dites nih
jawabannya pasti hasilnya setengah ya di
tengah itu maksudnya apa ya antara
khasnya ini tekanan tujuh setengah ini
dengan ini masuk AC rotate seperti ini
dia mungkin ada yang disini letaknya
tapi jarang saya belum pernah menemui
rata-rata letaknya di tengah-tengah
seperti ini
ini contoh untuk tentunya ya
ini contohnya Ini
contohnya Ini pakai typhoid watching ya
di sini ada dua Nia
22 titik ya Aduh 2.0 disini ini berarti
dari harus ke sini eh tujuh setengah Ini
kesini tengah ada ini panjang terletak
yang bawah ya yang 45 cm ini dari sampai
Natal kali depan seperti ini
transfer Ini contohnya hasilnya 51
akhirnya setelah dites ketemunya 5 1km
ya kita tahunya dari mayat dari dayanya
ini jadi saat kita sini sampaikan
maksimal biasanya patah di tengah Jadi
dua hancur menunjukkan angka beberapa
yang kita rata Ini hasilnya
yang kita nanti ditunggu ya Nah ini
contoh perhitungannya ya
Putri tunggalnya
kalau misalnya ini dengan metode typhoid
loading ya contohnya bebannya 35 knkn
kondisi benda uji tercanggih Tengah
metodenya type-c STMJ 78 hitung
konturnya penontonnya berapa ya kita
itung
kondisi pecah di tengah rumusnya prb D
kuadratnya stringnya 35km ini kalau
dikonversi ke kg karena nanti satuannya
kilogram per sentimeter persegi ya ah
ini satu KN = contoh koma 9 7 1 kg er
panjang meletakkannya pada mesin di b&d
jelas 15 ya Kita masukin umurnya PL
penerbit dikuadrat 35 v-nya l-nya 45 Ani
langsung dikonversi ya ke qnqq persatu
dikalikan ini
kantornya terus dibagi BD kuadrat yang
15 kali 15 Quadra ketemu
4758 kg per sentimeter persegi ini kuat
ongkirnya jadi SS berapa
fs4735 Va
Nah kalau di standar efeknya itu kece
fs45 dia kapal ini Grace hasilnya
memenuhi so ya seperti itu gampang kan
ini udara berhubungan sederhana gampang
Terus kalau kita gitu dengan metode yang
kedua yaitu metode Centerpoint Hah nih
mean hasil tespek kantor dengan beban
35km Berapakah nilai kuat lenturnya
wangi dites ketemu Bandi K5 km berapa
fakturnya rumusnya kita harus tahu dulu
dan ingat ya rumusnya tiga kali plp2b C
kuadrat
1km ini = 101 plus 971 kg ah tinggal
kita masukkan saja nih
tiga kali P banyak 35km kalikan l
panjang perlambang peletakan 45
dikalikan angka konversi satu kain ya
karena Kya
101,0 971 kg dibagi
dua kali BD kuadratnya B mimpinya 15
dikuadrat 15 ha15
ini ketemu 4818 13 dibagi 6750 ketemunya
7 1,3 Cup kg per sentimeter persegi jadi
efeknya berapa ya ini semuanya ya
Sederhanakan mudahkan ini sebenernya
sangat-sangat sederhana yang penting
kita tahu rumusnya kita tahu metode
Seperti apa kita tinggal masukin file
rumus terstruktur Oke semoga video ini
bermanfaat bagi
kita semua ya rumah terutama untuk yang
lebih belajar tentang
kuat lentur beton ya
