Abstract
Concrete beam is one of the common components in building structure, in the long-term use process, may be affected by various factors and damage, such as chloride ion penetration, carbonization, cracks and so on. Therefore, it is of great significance to study the failure mechanism of concrete beams. This paper analyzes the failure of a reinforced concrete beam by using the method of display dynamics simulation, analyzes its failure process, the research shows that: When the beam is subjected to load, it has a large displacement and deformation. The maximum displacement is 164.12mm; the stress distribution is uneven, and the maximum equivalent stress is about 25Mpa; after the load reaches a certain degree, the beam appears obvious cracks and failures, and the scope of failure gradually expands with the increase of the load.
