ABSTRACT
The design and calculation of the suspended patio floor structure with a span of 25.2 m and an opening diameter of 20.8 m of Shandong Bohai advanced technology research institute are carried out. To study the stress law of the large opening structure of the floor slab, the finite element analysis of the mechanical indexes of the round hole diameter and the floor structure layer thickness is carried out by using ANSYS finite element software. The results show that the stress at the hole edge beam and support is larger when the opening is smaller, and the stress level at the hole edge beam and support decreases significantly with the increase of the opening diameter. Cross-sloped beams with large open edges were studied using steel or reinforced concrete beam-slab structures. The bearing capacity and deflection need to meet the design requirements.
