  1. 1ª Empresa de transferência de tecnologia entre Brasil e Rússia neste segmento INSPEÇÕES EM FUNDAÇÃO DE CONCRETO 4º ANO Certificada ISO 9001:2008

  2. O SISTEMA Equipamento de inspeção em fundações de concreto. Pile Testing System

  3. A APLICAÇÃO Sistema de avaliação rápida e simples.

  4. Pile Testing System Low Strain Test Method • Based on measuring bar wave response to small hammer impact • Measures in both time domain and frequency domain • Can measure dynamic stiffness, length and mobility

  5. Pile Testing System Frequency Domain XFer FFT Mobility Force/Frequency Force/Time FFT XFer Velocity/Frequency Velocity/Time

  6. t Frequency domain ½∆F ∆F Frequency Length = velocity / 2 ∆F Fixed End Condition - Undamped Time domain Time Length = velocity x time / 2 Fixed End

  7. Fixed End Condition - Damped Head Response – time domain Effectively an increase in pile impedance Increase in sectionStiff Soil InterfacesRock Socket Time Head Response – frequency domain Frequency

  8. ∆F ∆F Un-damped Free End Condition Time domain Length = velocity x time / 2 Frequency domain Free End Length = velocity / 2 ∆F

  9. Free End Condition - Damped Head Response – time domain Effectively a decrease in pile impedance: Pile Toe/CrackDecrease in QualitySoft Pile Toe Time Head Response – frequency domain Frequency

  10. Length = c/2∆f Mobility = 1/ρcA Stiffness = 2π f(m) V/F(m) Impulse Response (Mobility) Curve VF V/F Frequency
