Abstract
Placement of the structure on a sloping surface has caused a short column to form in an irregular structure. For structures located on a sloping surface, it is necessary to take special precautions against explosive loads, such as the effect of an earthquake. In this research, a reinforced concrete frame with a moment frame system on the ground surface with slopes of 7, 14, and 21% under the effect of explosion load to a mass of 1000 kg from a distance of 3 meters from both sides of the top and bottom of the slope is investigated. The frame on a flat surface is compared. The results of this study show that the highest von Mises stress created in concrete occurred on a slope of 21%. This value is about 80 MPa, which compared to the slope of 0, 7 and 14% has shown an increase of 3.5, 33.3, and 68.4%, respectively. The maximum lateral displacement of the roof is also obtained for a slope of 21% when the blast load is applied from the top of the slope to the frame. The support reaction at the foot of the columns for a slope of 21% for both loading modes at the top of the slope and at the bottom of the slope was 1684 kN compared to 832 kN for the frame on a flat surface, which is a 100% change.
