The structural design of the EPS lattice slab is common in residential and small-scale projects, as it meets the client's needs. However, to be successful in the execution and preparation of the project, it is necessary to have technical knowledge in reading and representing this type of structural element. In this video, I show you step by step how to read all the information contained in the project board. ????

The lattice slab is very common when we need to reduce the weight of the structure, since we can adopt this structural element in single-family or multi-family residences. The structural project must be represented in a clear and objective way, so that once it is executed you will have no difficulty in interpreting the document. In the structural project of the lattice slab with EPS, we must represent each panel of the slab, that is, all the slabs must be identified and dimensioned, with the numbering starting from the top in the direction from left to right. However, there is no established standard for graphic representation, and each calculator can represent it in the way he or she finds appropriate. In particular, the representation adopted is the identification of the slab, with the type of slab, in the case adopted it was the LT-12 slab and the counter deflection. Next to the counter deflection I represent the direction of the reinforcement with a filled triangle. Another point that cannot be left out is the direction of the reinforcement of the slab, whether it is unidirectional or bidirectional. A quality factor of the structural project is the table that must accompany the information of the structural elements plan, which must include the position of the slab, type of slab, counter-deflection, additional reinforcement, main span and secondary span. The concrete cover is related to the LT-12 slab model, where it is 7 cm high and 5 cm of concrete cover. The details must be identified and identified by arrows with the legend. Good studies.
