The experiment was carried out on both dense and loose sand conditions at various confining pressures. Several types of anchors were investigated, they included smooth, rough, and ribbed anchors with different rib spacings. In dense sand, degradation that results in increasing void ratio occurs at the interface, therefore anchor resistance decreases in subsequent cycles. In loose sand, the degradation tends to decrease the void ratio at the interface. As a result, anchor resistance in subsequent cycles is either relatively constant or increases. The contribution of passive resistance on the ribs and friction at the interface results in a coefficient of apparent friction (μ *) for both the peak and the residual conditions. The value of μ * is influenced by compressive normal stress, soil density and rib spacing, whereas the coefficient of lateral earth pressure at rest (Ko) has little influence on the anchor resistance. © 2009 IOS Press.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]A-coefficient,Coefficient of lateral earth pressure at rest,Confining pressures,Cyclic loadings,Dense sands,Experimental studies,Loose sands,Normal stress,Passive resistance,Pullout resistance,Rib spacing,Soil density,Triaxial testing,Void ratios[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Anchors,Cyclic loading,Rib spacing,Triaxial testing tank[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.3233/978-1-60750-031-5-546[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
