Análise da capacidade resistente residual em estruturas de betão armado - estudo de caso

Abstract

This professional internship report is the result of activities that were carried out at the Mozambique Engineering Laboratory for six months. In addition to the insertion of the student in the practice of civil engineering, the activities carried out had as their main objective the harmonization of theoretical and practical knowledge; In this context, activities were developed in two main sectors (sectors of the DMCE): Concrete and aggregates Sector, Structures Sector. In the Concretes and Aggregates sector, among several tests carried out, the most requested stand out: characterization tests of the materials for the composition of the Concrete, and compression test of cubes/carrots. In the Structures Sector, precast tests were carried out (Sashes, beams and joists). A work was developed to evaluate the residual resistant capacity of a building, which is the core of this report. The study was conducted in two main phases of the preliminary evaluation phase and the detailed evaluation phase. In the preliminary evaluation phase, the visual inspection of the building, registration and mapping of pathologies, evaluation of the Carbonation of the Concrete, chloride and sulfate content was made; in detailed evaluation, the reconstitution of the architectural and structural project of the building, collection of materials for tests (compression of carrots, reinforcement traction) and structural analysis of the building were made. The crossing and compatibility of all results culminate with a suggestion of recovery or not of the building, presented in the chapter of conclusions and recommendations.
