Abstract

A local identification technique is developed to analyze the response of soil and soil-structure systems utilizing measurements from a newly developed Wireless Shape-Acceleration Array (WSAA). Local analyses of the constitutive behavior of these systems are performed using acceleration records provided by a cluster of closely spaced sensors. The developed new technique does not require the availability of boundary condition measurements, or solution of an associated boundary value problem. The constitutive behavior at a specific location is analyzed independently of adjacent response mechanisms or material properties. Numerical simulations of a soil-retaining wall system were used to demonstrate the capabilities of this local system identification technique. The combination of the developed Wireless Shape-Acceleration Array (WSAA) and local identification technique constitute a step toward autonomous monitoring technology and analysis tools capable of providing a realistic picture of acceleration, large deformation and failure of soil and soil-structure systems.
