The most important step in which architects, mechanical engineers and structural engineers have to coordinate and interact with each other in the design of architectural and structural elements, in the design of openings and ducts. In one direction, due to architectural designs, Moving facilities, etc. it is impossible to ignore the presence of opening on the structural floor, and in the other hand, the location of these opening can not be selected due to structural constraints solely based on taste and artistic designs. There fore, according to the project conditions and structural maps, the optimal site architecture and architecture should be selected and designed based on the factors. In this article using ABAQUS limited element software, we examine the effect of different variations of opening, such as the shape and position on the roof of an arched concrete slab.
In this article concrete slabs with a diameter of 1000 to 1000 mm and a thickness of 60 mm, and opening with a surface area of 10% of the total concrete slab surface are modeled in rectangular, circular and triangular shapes. Based on the result of this research, it can be seen that due to the compassion of different shape, The best performance in terms of minimal displacement is the reinforced concrete slab with a circular opening, with a 30% increase in the value of the displacement relative to the without opening state and the weakest performance of the RC slab with triangle bursts, with a 75% increase in the value of the displacement relative to the without opening state
