(Universidad Santo Tomás, 2026-06-09) Gómez Bermúdez, Ana Grabriela; Moreno Bautista, Daniela; Vargas Parra, Julián Ándres; Universidad Santo Tomas
Over time, the machinery used in construction has undergone significant transformation. In its beginnings, the works were executed mainly by human and animal force, using basic tools such as levers, ropes, pulleys and wooden rollers. Despite their technical limitations, these instruments managed to build important old structures, although the process was slow and physically demanding. The main and one of the most important changes came with the industrial revolution, a period in which steam-powered machines emerged, capable of transforming thermal energy into mechanical energy. This allowed for the advancement of pumps, industrial equipment, locomotives and vessels, boosting industrialization and improving production capacity and transport. As a result, the contractile processes became more efficient and dynamic. In the 20th century, the incorporation of internal combustion engines gave rise to heavy machinery such as excavators, cranes, tractors, concrete mixers and loaders, among many others. Over the years, these equipment have been perfected becoming more powerful, safe and specialized, allowing specific activities such as earthmoving, compaction, demolition and paving to be carried out with greater precision. In conclusion, the evolution of machinery has made it possible to optimize construction processes, increasing productivity and performance, reducing physical effort and facilitating the execution of large-scale works worldwide

This research aims to establish geotechnical criteria based on soil typologies for the selection and design of foundation systems applicable to non-conventional housing located in rural areas of the department of Boyacá, Colombia. The study is developed considering the high geological and geotechnical heterogeneity of the region, as well as the soil–structure interaction characteristics of lightweight structural systems. Soil characterization is carried out through the application of the Unified Soil Classification System (USCS), which allows the identification of geotechnical soil typologies with similar mechanical behavior and the analysis of phenomena such as differential settlements, uplift induced by moisture variations, and loss of bearing capacity. Based on secondary geotechnical information, bibliographic analysis, and regulatory review, representative stratigraphic profiles are defined and the performance of different foundation systems is evaluated using simplified soil–structure interaction models. The study incorporates the guidelines of the Colombian Seismic Resistant Code NSR-10, considering regional seismic hazard and site parameters associated with soil conditions, in order to ensure compatibility between the foundation system and the lightweight superstructure. As a result, a geotechnical decision matrix and a set of technical recommendations are proposed, linking soil typologies, geomorphological conditions, and lightweight structural systems with technically viable foundation alternatives aimed at improving structural performance and safety in non-conventional rural housing.

This research on pavers involved executing an experimental phase, classifying the material and identifying specific dosage references for constructive adobe, clay masonry, soil-cement mixes, and material testing dosages for road construction. The study follows applicable standards to evaluate physical properties such as density; chemical properties like efflorescence; and mechanical properties like the compression of pavers designed from different soil-cement mixes functionalized with an organosilane-type additive, which was used to enhance the product's strength and durability. Dosages of cement-treated soils were prepared following the PCA (Portland Cement Association), INVAS standards, and subsequently with Terrasil addition based on theoretical concepts, showing significant improvements in hardness and disproportion resistance. These properties depend on several factors, such as the soil's inherent characteristics, the cement proportion used, the mixing process, compaction, curing, and the amount of water present during stabilization. Preliminary phases, such as extraction from materials of the Tilatá Formation located in the municipality of Soracá, Boyacá, were conducted. Experimental tests were carried out in the geotechnics and structures laboratories of Universidad Santo Tomás, Tunja campus, guided by Colombian standards that establish fabrication criteria and use in the construction industry, where it serves as one of the region's primary raw materials. The results enabled establishing optimal soil-cement and Terrasil dosages for the Tilatá Formation soil, evaluating its mechanical behavior based on humidity and curing periods.

Manual de hidráulica aplicada: aforos, curvas de calibración, pérdidas menores y modelado en EPANET
(Universidad Santo Tomás, 2026-03-18) Lemus Riaño, Jair Orlando; Cortes Zambrano, Melquisedec; Universidad Santo Tomás; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001404409; https://scholar.google.com/citations?user=bDodlAUAAAAJ&hl=es; https://orcid.org/0000-0002-6073-3391
This manual presents an experimental and simulation-based methodology for the hydraulic analysis of pumping systems and pressurized pipe networks. The proposed approach integrates laboratory measurements, uncertainty analysis, and hydraulic modeling using EPANET software. Initially, volumetric flow measurements are carried out through volume–time gauging using graduated cylinders and a stopwatch, allowing the determination of flow rates and the evaluation of measurement reliability through statistical analysis. Subsequently, pressure data obtained from manometers are used to construct the pump characteristic curve (H–Q), which represents the real hydraulic behavior of the pumping system. Based on these results, minor head losses generated by fittings and accessories are calculated using the equivalent length method together with friction factor estimation. Finally, the experimental data are incorporated into a hydraulic model in EPANET to simulate pressures and flows within the network and compare them with measured values. The methodology ensures consistency between experimental measurements and numerical simulation for hydraulic system analysis.
