Controlling Deflection in Concrete Slabs
The deflection in slabs represents the vertical displacement under load. Therefore, rigorous control of this parameter ensures the integrity of the building. Furthermore, excessive deformation compromises not only the aesthetics but also the structural safety. Thus, the technical analysis must be precise from the design phase.
Torsional Rigidity and Stability
Torsional stiffness acts as a determining factor in containing deformations. In this sense, our solutions focus on the real mechanical behavior of the elements. For example, when designing large-span slabs, we consider the interaction between beams and columns. Consequently, we avoid unwanted cracks in masonry and cladding. Similarly, we analyze the modulus of elasticity of the concrete to predict long-term behavior.
Technical Challenges in Large Spans
Often, the height of the cross-section is not enough to contain the deflection. Therefore, we use reinforcements or prestressing when necessary. Moreover, WGB's experience allows us to optimize material consumption without sacrificing performance. Let's take as an example a recent project near the iconic São Paulo Museum of Art (MASP), In this project, precision in calculations was crucial to overcoming the limitations imposed by the region's bold architecture. Therefore, we applied advanced modeling methods to ensure the necessary rigor.
The Importance of Technical Standards
Brazilian standard NBR 6118 establishes clear limits for immediate and deferred deflections. However, simply following the standard does not guarantee absolute user comfort. Therefore, at WGB, we adopt even stricter criteria to ensure excellence. Furthermore, concrete creep requires constant attention throughout the structure's lifespan. Thus, preventive monitoring is essential for high-performance buildings.
