    Evaluación de la estructura de la capa de rodadura de la vía La Merced en el tramo km 0+000 al km 4+200 del cantón Pujilí de la provincia de Cotopaxi

    The road connecting Pujilí canton, specifically in the La Merced neighborhood, from kilometer 0+000 to kilometer 4+200, is in a considerable state of deterioration, negatively affecting both road safety and traffic flow. This situation poses an increasing risk to users and hinders efficient transportation in the area, making it imperative to implement corrective actions. To address this, a comprehensive road maintenance and conservation plan has been developed. This plan includes a detailed analysis of vehicular traffic, a superficial and structural evaluation of the pavement, a proposal for a pavement structure tailored to current and future needs, and the preparation of a referential budget. According to the vehicular traffic study, the Annual Average Daily Traffic (AADT) is recorded at 1,841 vehicles per day, with a projected increase to 3,398 vehicles per day by 2044, highlighting the urgency of immediate intervention. Additionally, the pavement evaluation revealed an average Pavement Condition Index (PCI) of 58, indicating irregular conditions that necessitate maintenance. The plan proposes specific interventions for the identified sections, including milling and cleaning of the terrain with removal of the vegetative layer. The total estimated cost for these works is $516,582.04 (five hundred sixteen thousand five hundred eighty-two dollars and four cents). Once implemented, this project will not only improve the structural and functional conditions of the road but also enhance user safety, promote more efficient traffic flow, and facilitate road maintenance management by the Decentralized Autonomous Government of Pujilí canton. Furthermore, these actions will contribute to the socio-economic development of the region by providing safer and more sustainable transport infrastructure.

    Evaluación estructural del pavimento de la vía San Juan, que va desde la intersección entre San Bartolo y García Moreno a las comunidades de García Moreno, Chacata el Carmen, San Juan y San Jacinto, cantón Santiago de Pillaro, provincia de Tungurahua, Ecuador
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2024-08) Moya Arias, José Lizandro; Nuñez Aldas, Galo Wilfrido
    Pavement structural evaluation is crucial to ensure the durability and functionality of transportation routes. This study focused on the structural evaluation of the pavement of the San Juan Road, which connects several communities in the Santiago de Píllaro Canton, province of Tungurahua, Ecuador. Various methods and tests were used to determine the real conditions of the pavement and propose improvement solutions, the PCI condition determined that more than 50 percent of the road is in poor condition, the deflection method with the Benkelman beam indicated that the 80 percent of the road needs reconstruction; The excavation of 4 pits every 500m was carried out, obtaining 70kg of soil that was used in the laboratory tests, determining that the subgrade is in good condition while an improvement is needed in the Base and Subbase; For the design of the pavement structure, a design CBR of 19.82 percent was calculated with a 75 percent percentile, a future traffic of 1590 vehicles/day was calculated, the road was categorized as class II, in the same way it will be built with a 10 cm class II Base and a 15 cm class II Subbase with a 5 cm thick asphalt layer As a result, horizontal and vertical signage will be placed with the general cost that the maintenance of the San Juan Road will require with a length of 4.5 km and a lane width of 6m.

    Evaluación de vulnerabilidad sísmica de edificaciones de estructuras metálicas en la parroquia Santa Rosa zona 2, Ambato, Ecuador: propuesta de reforzamiento estructural de una edificación representativa
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Maestría en Ingeniería Civil con Mención en Estructuras Metálicas, 2023-03) Carranza Calero, Diego Mauricio; Caiza Sánchez, Pablo Enrique
    Seismic vulnerability is a magnitude that allows quantifying structural damage, failure modes and resistant capacity under the action of an earthquake, which is based on the characteristics of the structure. The present work was framed in the vulnerability analysis of metallic structures of the Santa Rosa parish, Zone 2, which has a high level of seismic hazard due to its location and proximity to several geological faults. It was found that most of the metal structure buildings analyzed present a high vulnerability index that indicates that they would suffer great damage in the event of an earthquake. The evaluation criteria used were based on three methodologies: NEC 15, FEMA P-154 and FUNVISIS: perform a more exhaustive analysis, draw vulnerability and seismic risk maps and identify a representative building to perform a detailed analysis and propose a reinforcement proposal, in this building three types of analysis were performed: static, spectral modal and Pushover to identify the critical points of the structure that should be reinforced.

    Evaluación estructural estática y dinámica del muelle marítimo ubicado en la Base Naval Sur Guayas, en la ciudad de Guayaquil
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2022-06) Frías Córdova, Christian Fabián; Cevallos Cabrera, Jorge Washington
    The present qualification work consists of a quantitative evaluation in order to know the behavior of the service pier after the impact received by the vessel M.H. HUALCOPO. Once the field information was collected, it was found that the pier had several damages, being the most dangerous the cracks and fissures in the inverted T-beam and the piles that support it, in the same way it was found that there is detachment of the coating in several areas of the pier and a great amount of rust present in the places where the reinforcing steel is exposed. Once the visual inspection was carried out, a sclerometric test was performed, where it was verified that the resistance of the piles decreased considerably in comparison to the resistance obtained through the studies carried out by the naval entity some time ago. Once all the field information had been compiled, as well as the structural and architectural drawings, the numerical model of the pier was made to perform the corresponding static and dynamic analyses, where it was verified that the structure behaved very badly under seismic stresses, mainly generating excessive periods and drifts. Subsequently, a Pushover analysis of each of the pier's frames was performed based on the displacements produced at the moment of impact by the ship, finding that the performance of the aforementioned frames is higher than the collapse prevention performance, which is consistent with the visual inspection of each of them. The studies carried out showed that the service pier has a very poor performance under dynamic stresses and a reinforcement would result in an excessively high cost due to the level of performance it presents, the poor structural configuration for the site where it is located and the advanced degree of deterioration it ha
