| Title of the article | On the issue of strengthening vaults («Monier» type) with composite materials in the reconstruction |
| Abstract. | Problem statement. Currently, in normative documents there is no methodology for calculating the reinforcement of brick vaults on metal beams («Monier» type) with composite materials, and therefore its development is an urgent task. Results. Static calculations of a fragment of vaulted ceilings on steel beams were performed taking into account the presence of structural defects, increased load on the floor and the use of various amplification schemes with two types of composite materials. Deformations of elements, characteristic zones of stress distribution, the sequence and nature of cracking for specimens without reinforcement and defects, without reinforcement with a defect, were established for various reinforcement schemes with composite materials at all stages of loading until the structure is virtually destroyed. A comparison of the results for various amplification options made it possible to establish the most effective of the considered schemes. The values of cracking and destructive loads for all considered structures are obtained. Conclusions. The significance of the results for the construction industry is to confirm the effectiveness of the use of composite materials to strengthen Monier type vaults. A technique for assessing the strength and deformability of arches on steel beams when reinforced with composite materials is proposed, which allows to evaluate the effectiveness of the structural solution. |
