Análise crítica de patologias provocadas em juntas de dilatação estruturais de edifícios verticais

Abstract

The concept of expansion joints is intrinsically related to heat and movement. With technological advancements and studies on materials, it is observed that concrete in large structures has a significant tendency to expand and undergo slight movements. This characteristic can become a critical issue in rigid and robust structures. In this context, expansion joints emerge as an effective solution, allowing the structure to move in a controlled manner, ensuring safety, functionality, and, most importantly, preventing the development of structural pathologies. To address pathologies and ensure the lifespan of structures, this study presents different filling methods for expansion joints, with a focus on proper sealing. Joints can be filled with various types of materials, such as elastomers and sealants, or even with pre-fabricated neoprene rubber profiles, which combine technical efficiency and aesthetic appeal in a single product. Regardless of the material chosen, it is essential that the design and execution of expansion joints be carried out meticulously, ensuring the desired performance and contributing to the durability and safety of buildings.
