Autor(es): Araújo, Hyan Gabriel Felipe Primeiro Orientador: Santos, Matheus Tabata Abstract: This Final Course Project presented a comparative analysis between conventional masonry and structural masonry construction systems applied to social housing in the state of Goiás. The research was conducted through a real case study, encompassing the quantitative survey of materials, budget analysis, evaluation of technical performance, preparation of the physical-financial schedule, and application of the ABC curve. The results show that structural masonry offers advantages related to sustainability, waste reduction, and speed of execution, making it a suitable solution for standardized projects. In contrast, conventional masonry presented lower direct costs and greater constructive flexibility. It is concluded that the choice of construction system should consider the specific context of the project, in order to contribute to the rationalization of the Brazilian construction industry and provide technical, academic, and institutional support for decision-making.

Autor(es): Calixto, André Luiz Andrade Soares Primeiro Orientador: Queiroz, Angela Custódia Guimarães Abstract: The choice between flexible and rigid pavements represents a strategic decision in Brazilian highway engineering, especially in the context of continuous fleet growth and the increasing demand for structural performance and cost optimization throughout the service life of roadways. This study presents a literature review based on manuals from the National Department of Transport Infrastructure (DNIT), specialized technical literature, and consolidated design methods such as the traditional empirical method, MeDiNa, and PCA/84, addressing structural criteria, materials used, construction techniques, durability, and associated costs. The adopted methodology consisted of a bibliographic review and the comparative application of pavement design methods to a case study involving a section of BR-153 highway, near Pirenópolis, Goiás State, considering traffic parameters, subgrade characteristics, and design period. Based on the structural design and the estimation of construction and maintenance costs, differences in mechanical performance, resulting thicknesses, and economic impacts over the service life were analyzed. The results indicate that, although rigid pavement presents a higher initial construction cost, its lower frequency of interventions and greater durability may make it more advantageous under conditions of heavy traffic and long design periods. It is concluded that the choice of pavement type should consider not only the initial investment, but primarily the integrated analysis of structural performance and life-cycle cost throughout the highway’s service life.

Among the most common techniques is concrete casing and additional reinforcement, whose effectiveness depends on good adhesion between the old and new concrete, often provided by metal connectors. The overall aim of the research was to evaluate the performance of columns reinforced with increased cross-section and reinforcement with connectors, considering load capacity, stiffness and failure modes, taking into account the impact of using different types of connectors. To this end, a literature review was carried out of experimental studies by authors such as Takeuti (1999), Omar (2006), Sahb (2008), Nascimento (2009), Marques (2014), Ferreira (2014) and Virgens (2015), who investigated the behavior of columns subjected to flexion-compression with different reinforcement configurations. Analysis of the results showed that although the reinforcement provides a significant increase in strength and stiffness, there is a need to improve the form of rupture to ensure greater structural safety. The adherence between the concretes and the anchoring of the connectors proved to be fundamental in this process. Anchor bolt type connectors, pin type connectors and open stirrups were used with varying performance, indicating that the rate and distribution of these elements directly influences the effectiveness of the reinforcement. The conclusion is that reinforcing columns by partial encasement is an efficient technique, as long as it is carried out with strict control of the materials and special attention to the interface between the concretes.

Initially, an in-depth literature review was conducted on conventional concrete, its properties in the fresh and hardened state, as well as the history, types, applications, and mechanisms of action of metal fibers, especially steel fibers. Six concrete mixes were prepared: one reference mix (without fibers) and five with macrofiber additions at contents of 0.5%, 1.0%, 1.5%, 2%, and 3%. The workability of the mixtures in the fresh state was evaluated using the slump test, while the properties in the hardened state were analyzed by tests of axial compressive strength, diametral compression tensile strength, flexural tensile strength, and modulus of elasticity, in accordance with ABNT standards. The research aims to identify the contributions of metal fibers to improving the mechanical strength and ductility of concrete. The results obtained allowed for a comparison of the performance of fiber-reinforced concrete with conventional concrete, helping to define more efficient dosages and encouraging the use of fibrous materials in civil engineering.
