Seismic Analysis of a School Building
With Reinforced Concrete Panels

This paper aims to present, on the example of a reinforced concrete school building, a comparative analysis of its behavior due to the effects of an earthquake through 4 fundamentally different models. The school building has a frame structural system with reinforced concrete walls, while the other models were created by adding and subtracting vertical and horizontal structural elements. The most prominent problem of this structure of the school building is the very high stiffness, which is the result of the existence of a dense system of underground and above-ground walls. This paper includes the calculation of required and adopted reinforcement, as well as displacement control, and inter-storey drift control, respecting the provisions of Eurocode 8. Based on the calculation results, certain conclusions were drawn, and some possible solutions were also proposed to potentially improve the building.
