One way to reduce the mobilization of the earthquake forces in in-filled frames structures is by using lightweight infill materials. Autoclaved aerated concrete (AAC) is one of the lightweight materials that can be used as infill materials. However, the knowledge on the behavior of frame structures in-filled with lightweight materials, such as AAC blocks, under in-plane lateral loads is still limited. This paper presents experimental research conducted to study the in-plane behavior of R/C frames in-filled with AAC blocks. The tests are performed on two single bay, single story in-filled frame specimens with 1/2 scale models. One of the test specimens is in-filled with conventional clay brick materials and the other is in-filled with AAC blocks. The loading used in the tests is in the form of cyclic in-plane lateral loads, simulating earthquake forces. The objective of the tests is to study the influence of physical and mechanical characteristics of the infill materials used on the resulting seismic performance of the test specimens. Behavior of the frame structures is evaluated through the observed strength and deformation characteristics, and also through the measured hysteretic energy dissipation capability.[/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]Autoclaved aerated concrete,Hysteretic behavior,In-filled frames,Infill materials,Lightweight materials[/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]Autoclaved aerated concrete,Ductility,Hysteretic behavior,In-filled frames,Infill materials,Lightweight materials[/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][/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]
