Thermal Integrity Profiling of Concrete Deep Foundations Data Analysis Session 4
Data Analysis Overview • Background (aka. theory) • Analysis Software • Sample Data Sets • Time of testing calculations
Single Shaft Heat Signature Elevated Shaft Concrete Temperature Distribution Higher Temperature Elevated Soil Temperature as well
Single Shaft Heat Signature Higher Temperature
Effects of Alignment or Radius Temperature (F) Radial Position (ft) Shaft Radius (ft)
X axis (independent) Y axis
Cage Offset • Compare Radii • T2 smaller than T4 • T3 smaller than T1 • Cage must be offset to the SE
TIP Data Setup • Field data input has limited input requirements • Update field data in TIP computer prior to starting the TIP Reporter software • Most significant • Tube length and stickup • Shaft and cage radius
Predicting Temperature Rise for time of testing Must know mix design with detailed cement and flyash reports (can change monthly) Must know geometry of shaft or other concrete element in question Must know environmental conditions (e.g. air temp, soil type, soil temp, etc.)
