Tipo de ítem: Ítem , Análisis Comparativo de los Criterios de Diseño Sísmico y del Uso de la Mampostería en Concreto en Colombia y República Dominicana.(Universidad Santo Tomás, 2026-04-10) Vargas Marulanda, Ronal David; Medina Sierra, Wilson Alfredo; Universidad Santo Tomás; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001435719; https://orcid.org/0000-0002-0454-3251Colombia and the Dominican Republic are located in areas of high seismic hazard, which has led to the development of regulatory frameworks for structural design. In Colombia, the Colombian Seismic Resistant Construction Regulation NSR-10 integrates the requirements for seismic and structural masonry design into a single regulatory body, while in the Dominican Republic these guidelines are found distributed in separate regulations. The academic mission allowed observing the widespread use of concrete masonry in low-rise buildings and motivated the comparison of regulatory criteria between both countries.Tipo de ítem: Ítem , Comparación de prácticas constructivas y control de calidad observadas en la Misión Académica Internacional en Santo Domingo y su posible aplicación en infraestructura educativa oficial en Colombia(Universidad Santo Tomás, 2026-02-12) Mahecha, María; Daza, AngelThe international academic mission carried out in Santo Domingo strengthened the training of structural engineering specialists through the observation of construction practices, structural systems, quality control processes, and regulatory frameworks. The study followed a descriptive and observational approach based on urban tours, an academic visit to the materials and soil mechanics laboratories of the Autonomous University of Santo Domingo, and the observation of an industrialized construction system using modular metal formwork. This work reflects on the importance of quality control, seismic-resistant regulations, and the academic interest in industrialized construction systems for public educational infrastructure in Colombia, without performing quantitative analyses or structural verification.Tipo de ítem: Ítem , Comparación de prácticas constructivas y control de calidad observadas en la Misión Académica Internacional en Santo Domingo y su posible aplicación en infraestructura educativa oficial en Colombia(Universidad Santo Tomás, 2026-02-10) María de los Ángeles Mahecha Sánchez; Daza Pinzón, Angel FranciscoLa misión académica internacional realizada en Santo Domingo permitió fortalecer la formación del especialista en estructuras mediante la observación de prácticas constructivas, sistemas estructurales, control de calidad y referentes normativos. El trabajo se desarrolló con un enfoque descriptivo y observacional, a partir de recorridos urbanos, la visita a los laboratorios de materiales y mecánica de suelos de la Universidad Autónoma de Santo Domingo y la observación de una obra con sistema constructivo industrializado mediante encofrado metálico modular. A partir de estas experiencias, se reflexiona sobre la importancia del control de calidad, la correcta aplicación de la normativa sismo resistente y el interés académico de los sistemas industrializados en el contexto de la infraestructura educativa oficial en Colombia, sin desarrollar análisis cuantitativos ni verificaciones estructurales.Tipo de ítem: Ítem , Revisión De los Parámetros de Diseño Estructural En Compuertas Hidráulicas de Grandes Obras: Análisis Comparativo Entre las Esclusas Del Canal de Panamá Y las Propuestas Para el Canal Del Dique en Colombia(Universidad Santo Tomás, 2026-01-30) Ruiz Pidiache, Laura Natalia; Vásquez Castillo, Lina María; Daza Pinzon, Angel Francisco; Universidad Santo TomásThe need to control flow rates, ensure navigability, and protect ecosystems in tropical river environments has driven the design of hydraulic structures such as sluice gates, whose performance depends largely on their structural characteristics. In tropical contexts, this design requires rigorous criteria to ensure strength, stability, and durability against hydrostatic loads, thermal effects, corrosion, and complex geotechnical conditions. The locks of the Panama Canal, especially after its expansion, are an international benchmark for their technical sophistication, with rolling gates capable of withstanding high hydrostatic stresses, earthquakes, and highly corrosive environments. In contrast, the restoration project for the Canal del Dique in Colombia involves similar infrastructure, facing challenges specific to soft soils, high sedimentation, and water variability, which raises questions about the adaptation of structural parameters in geotechnically different contexts. This project develops documentary and comparative research focused on the technical analysis of the structural parameters used in the Panama Canal locks (materials, geometry, closure systems, foundations, and regulations) to compare them with the proposals for the hydraulic control system of the Canal del Dique on the Caribbean coast of Colombia. The objective is to identify transferable structural principles that can be adapted to the Colombian context under standards such as Colombia NSR-10. The methodology includes a regulatory and typological review, together with a structural analysis aimed at constructing a comparative matrix as the main result. This research seeks to contribute to the strengthening of the national river infrastructure from a structural engineering perspective, generating relevant technical inputs for the design of floodgates in tropical settings with challenging geotechnical conditions.Tipo de ítem: Ítem , Evaluación del avance de la carbonatación en concreto bajo condiciones de alto trafico urbano: Caso Tunja, Colombia.(Universidad Santo Tomás, 2025-09-12) Barrantes Duarte, Angie Tatiana; Castellanos Castaño, Sara Alejandra; Medina Sierra, Wilson Alfredo; Universidad Santo TomasCarbonation in concrete is a progressive phenomenon that compromises the durability of structures, especially in urban environments exposed to high levels of vehicular pollution. This study focused on evaluating the impact of traffic on the advancement of carbonation in concrete by exposing cylindrical specimens in ten strategic locations in the city of Tunja, selected based on their varying levels of traffic congestion. The main objective was to identify whether urban environmental conditions significantly influence concrete performance over time. A four-phase methodology was developed: traffic analysis, specimen fabrication, six-month exposure in the field, and evaluation of carbonation depth. Results showed that although all specimens exhibited structural behavior within expected parameters, the depth of carbonation varied significantly between zones. This confirmed that the urban environment directly influences the rate of concrete deterioration. As a conclusion, a general zoning was established, identifying the areas most affected by this phenomenon in Tunja, providing a useful foundation for future decisions regarding the design, maintenance, and preservation of structures in the city.

The research is based on a review of relevant standards (NSR-10, ACI 318, and ASTM A1034), as well as on documented international and national experiences in high-rise buildings. The methodology included the identification of internationally recognized splice types, the verification of normative requirements through tensile testing, and the consultation of local applications, particularly in the Torre Atrio and Edificio Aguacate projects. Findings indicate that, within the Colombian context, mechanical splices have been mainly employed in post-construction solutions, such as continuity of previously cast elements, while conventional lap splices remain prevalent during the construction stage. The results highlight that national regulations allow the use of mechanical splices in columns under specific performance and location requirements, but their practical implementation in local projects is still limited. Moreover, it was confirmed that mechanical splices provide greater structural reliability in critical seismic zones, provided that they comply with the Type 2 classification of ASTM A1034. In conclusion, this research suggests that mechanical splices represent a viable and innovative alternative to improve safety and optimize construction processes in reinforced concrete structures in Colombia.
