| contents | Comparison between exact and approximated visco-elastic transfer functions for a resonant-column system Javier Camacho-Tauta Ingeniería Shear Visco column Resonant elasticity The resonant column test is the standard method in the laboratory to obtain the dynamic properties of the soil. The state of dynamic equili- brium during the test can be represented by a viscoelastic model that is expressed by a transcendent equation in complex variables. It implies that the solution of the equation to find the shear modulus and damping ratio should use fairly sophisticated numerical techniques. This article presents and compares an approximate viscoelastic equation that allows obtaining an approximate value of the dynamic properties of the soil. Finally, a set of resonant-column test was performed in order to verify the proper performance of the proposed solution. 2013 artículo científico 0122-3461 https://www.redalyc.org/articulo.oa?id=85229155002 en http://www.redalyc.org/revista.oa?id=852 Ingeniería y Desarrollo application/pdf Universidad del Norte Ingeniería y Desarrollo (Colombia) Num.2 Vol.31 |
