The effectiveness of a nonwoven geotextile–geomembrane liner as a foundation isolation system for RC buildings is studied analytically by considering artificial as well as recorded accelerogram as earthquake ground input motion. The concept of foundation isolation is applied by separating the foundation from the soil by a sliding friction interface in the form of geotextile–UHMWPE. A 3D finite element simulation and parametric study in ABAQUS have been carried out to estimate the effectiveness of the proposed method. The results show that through slip deformation, the interface reduces seismic energy transferred, reducing the dynamic response of the building. On an average, the proposed scheme can reduce the horizontal ground acceleration by 40%. |
