    Estudio y análisis del proceso de fabricación de cerchas de acero tipo HOWE para fortalecer la productividad de la empresa FYMSA, del cantón Salcedo–Ecuador

    In the search for new design alternatives for the construction industry, it is crucial for mechanical engineers to understand improvement criteria for a thorough analysis of metal structures. Interpreting regulations is a challenge that generates problems in the development of these projects, leading to non-compliance with standards, arbitrary actions, and erroneous decisions that have, in some cases, resulted in damage to infrastructure and compromised safety. Therefore, this research is experimental in nature, and the following hypothesis was proposed: the use of Howe-type trusses in FYMSA company is feasible as an alternative in the construction of industrial warehouses, considering their design, fabrication, and assembly. A comparative analysis was conducted with the trusses commonly used in the construction of industrial warehouses. Through qualitative analysis, the situation in the company was described, and deficiencies in the manufacturing process were identified. To determine the effectiveness of using Howe trusses, a non-linear Pushover analysis was performed, determining the ductility of the structure. It was found that the elements, when subjected to critical seismic loads, did not experience rupture, and the ultimate strength (Sut) limit reflected in the performance curves was extended by 80 percent less than Warren-type trusses. As a result, it was determined that the use of Howe-type trusses is feasible.

    Diseño y análisis del parqueadero central de la ciudad de Ambato de hormigón armado y estructura metálica con el uso de elastómeros en la cimentación

    In the present research work several factors are taken to determine the seismic safety of buildings, materials such as elastomers have been used for structural protection. The design and analysis of the central parking lot of the city of Ambato of reinforced concrete and metal structure with the use of elastomeric insulators in the foundation helps to improve seismic behavior. A modeling was carried out using software analyzing each of the structural elements, especially the behavior of the foundation. Structural and economic analysis shows that a structure equipped with elastomeric insulators in the foundation reduces its initial investment in the structural system since these are responsible for dissipating much of the energy that enters the system so the sections of the structural elements are reduced which implies savings. Its benefit is given in the long term reflected in the performance that the structure can achieve. In the analysis torsional distortion was visualized, we did not find the use of prequalified connections, factor of importance of the structure equal to one, vibration modes insufficient for a minimum mass participation of 90 percent, so we performed a verification through a linear analysis and a static nonlinear analysis with a factor of importance I = 1.5, , additionally, we must analyze the essential structures by means of a non-linear analysis for a return period of 2500 years as stipulated in the NEC SE DS 15. Therefore, this research determines the level of structural performance, as stipulated in the Ecuadorian Construction Standard in force, in the chapter of seismic design thus deducing that it was necessary to implement a structural reinforcement system, which at least allows the structure to remain at a level of (Life Safety) LS which is what the standard requires us.
