Problem Description

Problem Description

Problem Description

Design Constrains Factors of Safety Soil bearing capacity Against sliding ≥ 1.25 Against overturning ≥1.5 Soil bearing capacity ≤ 3 ksf ≥ 0

Excel Model Features: Easy to Handle Flexible Minimum Cost Time Saving

Excel Model Optimization

Model Importance Material Saving: For a pipe force: Fp=1502 lb; Typical Solution Obtained by Saudi Aramco Engineer: V=30*16*16=7,680 ft3 Excel Model: minimized to V=4,288 ft3 % Saving: =45%

Results Concluded The dimensions for a given force can be obtained using: Model (Solver) Tables Charts Equations

Results Concluded The dimensions are exponentially related to the pipe’s force magnitude Approximately Min 40% saving in material
