Tiang Pancang Xls | Perhitungan Kalendering

Then compare with design required capacity.

File perhitungan biasanya mencakup parameter dinamis berikut untuk menghitung kapasitas ultimit ( Rducap R sub d u end-sub : Berat palu ( Wrcap W sub r ), tinggi jatuh ( ), dan efisiensi palu ( Data Tiang : Berat tiang pancang ( Wpcap W sub p ) dan luas penampang. Data Lapangan (Grafik Kalendering) : Penetrasi ( ) : Masuknya tiang per 10 pukulan terakhir. Rebound ( ) : Pantulan balik tiang saat dipukul. Faktor Keamanan ( SFcap S cap F ) : Biasanya menggunakan nilai 3 untuk beban permanen. Formula yang Sering Digunakan perhitungan kalendering tiang pancang xls

– This is not a guess. Perform a dynamic load test (PDA) on at least 1–2 piles to back-calculate η for your specific rig and pile type. Then compare with design required capacity

– Prevent division by zero, negative S, or nonsense inputs. Rebound ( ) : Pantulan balik tiang saat dipukul

Rebound (C) is often estimated or taken as 10 mm for concrete piles with plywood cushion. Never assume zero rebound.

For final working load: [ R_allow = \fracR_uSF \quad (\textSF = 2.5 \text to 3.0) ]
