    Desarrollo de un software específico para el diseño de conexiones de arriostre o viga-columna para pórticos especiales arriostrados concéntricamente, conforme a la normativa ANSI/AISC 341 -16
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Maestría en Ingeniería Civil con Mención en Estructuras Metálicas, 2022-03) López López, Liliana Lizbeth; Pico Núñez, María Fernanda; Medina Robalino, Wilson Santiago
    The present research project has as purpose the codification of a specific software for bracing connections or beam-column connections design for steel special concentrically braced frames (SSCBF). It allows us to design in a quick and safe way the simple beamcolumns (bolted) connection, welded beam-column connection, double braced beam column (welded) connection, X brace-beam (welded) connection, simple beam-column (bolted) corner connection, and simple beam-column (welded) corner connection. For the design of the different connections, they were analyzed by ANSI/AISC 341-16 Standards criteria. From it the calculation equations for a design by capacity were taken. For the development of the software, we started with the manual calculation of the different connections, with this the software programming code was developed and at the same time the graphic interface for the visualization of the results was created. For the veracity of the SCBF DESIGN CONNECTION software, the results obtained by the developed software were compared with the manual method; resulting in a margin of error of less than 1.50 percent, thus verifying that the results obtained by the software are reliable.

    Desarrollo de un software específico para el cálculo de canales abiertos de flujo uniforme considerando los principios de energía
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Civil, 2018) López López, Liliana Lizbeth; Morales Fiallos, Fabián Rodrigo
    The present research contains the codification of a specific software to calculate open channels with uniform flow, considering the principles of energy, it allows to obtain easily and safely the normal depth, critical depth, geometric elements, flow rate, optimal hydraulic section proposed by Ven Te Chow, such as: rectangular, trapezoidal, triangular, circular, parabolic, rectangular with rounded corners and triangular with rounded bottom. Additionally, the geometric elements for any equation of the parabola, the highlight hydraulic and landfills. In order to validate the SN CANALES v2.0L software, the results obtained by using the existing software HCANALES were compared to the ones obtained by the proposed software and hand calculation step by step. The margin error was less than 1.5% which verified the software reliability.
