Avaliação de desempenho estrutural e manifestações patológicas em estruturas metálicas

Abstract

The paper it is a scientific and technological study about quality control in the fabrication and assembly of steel structures, developed through the analysis and interpretation of information obtained from literature surveys, technical visits and interviews with companies in the sector, highlighting the knowledge the existing literature. Therefore, they will discuss the processes for obtaining structural steel and its properties, the various stages of fabrication and assembly of steel structures, as well as nondestructive testing. The survey aims to define inspection criteria for the fabrication and assembly of steel structures for early identification of pathological manifestations, present the main pathological symptoms found in steel structures, establishing its origins and causes, exposing a flow chart of the process production of a steel structure showing the main performance checkpoints and, finally, to analyze certain pathological events, indicating failures in the production process. It is concluded that there are precautions to be observed not to make constructive errors, easily preventable through efficient planning and supervision. The study's aim is to promote the exchange of research results to the productive sector and assist in the review and development of standards.
