Stress Research in Hollow Core Flat Slab and Applications
Hollow core flat slab is currently a superior solution compared to traditional reinforced concrete slab in today's construction to help save materials, reduce construction time, thereby saving construction costs significantly while providing a variety of functionality. It brings cool and airy spaces while saving energy in line with the trend of green construction and sustainable energy development in Vietnam and in the world as well. This paper aims to examine the methods of structural calculation and stress analysis of hollow core flat slab through actual cases and then, compare the results of the calculation methods with the measured ones at the actual projects using hollow core flat slab. The finite element method of 3D modeling in commercial Etabs and Ansys software was used to simulate the stresses of the hollow core slab and the column mushroom area. A few simple formulas to calculate the equivalent exchange of flexural stiffness and slab weight were used in analytical methods. The results show that if using Etabs software in the design, the stress and deflection calculated by the wall method are the closest to reality while the slab method gives the biggest error. The achieved results and analytical data of this study can be used as a reference for engineers.
