Estudo comparativo da estabilidade global em diferentes tipos de lajes

The verification of the overall stability in reinforced concrete buildings is a very complex parameter regarding the strength and durability of the structure. In this work, we analyzed a structural model for three types of slabs, modeled by the AltoQi Eberick v10 software. The first model considers the massive slab portico. The second considers the building with ribbed slab and the third model with lattice slab. The results to be considered are the Gamma-Z coefficient and lateral stiffness. These analyzes were compared, and there was a difference in the load distribution to the beams, the displacements and consequently the stability of the building. It was also noticed that the Z-Gamma values ​​did not change significantly, showing that the gantry have the largest contribution. Thus, the results showed the importance of a comparative study between the slabs before the elaboration of structural projects, emphasizing the cost-benefit is also clear.
