Abstract

This work, made a gantry stiffness matrix plan based on principles of Timoshenko and adding the effect of normal stress, thereby obtaining a matrix on the local system. Using a graphical inspection was possible to obtain a coordinate transformation matrix which equated correctly transfers the array of the gantry plane stiffness of the local coordinate system to the global coordinate system. Considering the principle of discharge of secondary thickening was used Zaretsky rheological model for obtaining the discharge time, this model has similarities to the actual behavior of clay soils. The association of the two formulations was carried out using the method of direct rigidity to gates solution, both Timoshenko principle as the Euler-Bernoulli, adding the settlement provided by the formulation of the rheological model Zarestsky. Using the methodology of the method of direct stiffness held a mathematical formulation to verifying the possibility of its use.
