The experimental study aims to determine the ductility and energy dissipation of beam with hoops confinement in compression zone at the plastic hinge region under cyclic loading. Two half-scale beam specimens that conducted as a simplification model of beam plastic hinge region at column face were tested. The one specimen was confined with hoops and would be compared by un-confinement beam in compression zone. The beam will be loaded with load centered on the middle of the span so it will receive the greatest moment and shear. The cyclic loading system by using displacement control with the static squasi loading gradually reaches the ultimate state. The experimental test shows that confining with hoops in the compression zone of beam’s section increases up to 50 percent in displacement of ductility, and around 65 percent in curvature of ductility. Further, the cumulative index of energy dissipation of beam increase up to 2 times compared with un-confinement beam in compression zone. The confinement hoops of compression zone insignificant increase in terms of strength capacity and moments as well as in monotonic loading test.[/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][/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][/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/10.1063/1.5011489[/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]
