However, the occurrence of defects, such as pores, during manufacturing processes can alter the effective properties of these materials and, consequently, their mechanical response. In this context, the present study proposes an extension of Pagano’s analytical solution, which is based on the three-dimensional Theory of Elasticity, for the static analysis of sandwich beams with a functionally graded and porous core. To represent the continuous variation of the material’s mechanical properties, an approach based on the discretization of the material into equivalent homogeneous sublayers was employed. The developed formulation was validated by comparison with results available in the literature. Subsequently, a parametric study was conducted considering different material gradation indices, porosity indices and distribution models, slenderness ratios, and geometric configurations of the layers. The results demonstrate that these parameters directly influence the structural response, highlighting the importance of analyzing the behavior of these structures by considering the combined effects of these factors.

However, it is also characterized as one of the industries that consume the greatest amount of natural resources and raw materials, thus being one of the main contributors to environmental impacts. Among the emerging sustainable alternatives, the use of engineered wood products, such as Glued Laminated Timber (Glulam), stands out. This technology presents significant advantages since, besides being an efficient structural solution, it uses a renewable resource and contributes to the reduction of carbon emissions in construction. The advancement in the use of Glulam has generated considerable interest due to its versatility and potential application in various structural systems. This study aims to analyze the flexural design of Glued Laminated Timber (Glulam) elements, addressing the technical aspects involved in their structural behavior, with a focus on beams subjected to bending, highlighting their role in the pursuit of more sustainable practices in civil construction.

In this context, new research has emerged on a composite consisting of fine-aggregate concrete reinforced with multiaxial textiles, which can be made of natural fibers, basalt, carbon, or glass. This composite has become known in the literature as Textile Reinforced Concrete (TRC).The focus of this work is the study of TRC applied as structural reinforcement for reinforced concrete beams subjected to bending, as well as the development of a computational program for the design of such reinforcement. To achieve the main objective, a literature review and an analysis of the calculation methods available in the literature were conducted. The program was developed in Python, and its code is available in Appendix B.The results obtained were analyzed and compared with experimental data from the literature, showing that Beber's model presented a high correlation with experimental data, while Trintin's model revealed a more conservative character. Furthermore, the high efficiency of national fiber was observed, signaling a promising path for the development of this technology in Brazil. The developed computational tool proved to be a practical and agile mechanism for the comparative analysis of calculation methods, validating the structural safety of the reinforcement. Finally, the study points to the need for greater fiber standardization and the expansion of experimental testing to support future national standardization.

The tool contemplates simple beams, built-up beams composed of two members, and built-up beams composed of three members, considering the partial interaction between the elements through semi-rigid connections. The calculation procedure includes the determination of design resistances, normal and shear stresses, internal forces acting on the connectors, and the verification of instantaneous and final deflections. The validation of the tool was carried out through the comparison between analytically obtained results and those automatically generated by the spreadsheet, showing a high agreement between the methods, which confirms the consistency and reliability of the developed model.
