Pantalla del editor del lenguaje de programación donde se introdujeron los valores y ecuaciones para realizar todas las tareas y comandos necesarios para ejecutar el predimensionamiento del muro, ecuaciones para el cálculo de los empujes dependiendo de las condiciones del terreno el volcamiento, el deslizamiento y los esfuerzos sobre el mismo a fin de chequear que los valores de factor de seguridad estén dentro de los parámetros de diseño.

Una vez obtenida la pantalla de salida del sistema por ingresan los datos y parámetros de análisis, se procedió a realizar un ejercicio comparativo donde puedan evaluar los resultados obtenidos por el sistema computarizado y los obtenidos en forma manual, obedeciendo al siguiente procedimiento:

1. obtener los valores de los ángulos de fricción del suelo a contener y del apoyo del muro, para así hallar coeficientes de empujes de tierra (activo y pasivo).
2. Conocida la altura H del muro, se debe determinar las dimensiones de sus elementos.
3. Hallar las resultantes de los empujes de tierra y sus puntos de aplicación.
4. Calcular la magnitud de todas las cargas gravitacionales, debido al peso propio del muro y la tierra que se apoya sobre el pie y el talón.
5. Determinar la resultante R, producto de las cargas.
6. Calcular el momento de volcamiento con respecto al punto I del extremo del talón.
7. Hallar el momento estabilizante con relación al mismo punto I, con y sin empuje pasivo.
8. Calcular el acero principal del fuste del muro, colocado verticalmente, junto al paramento interior, y en el pie del muro, horizontalmente, junto al borde respetando los recubrimientos mínimos según la norma covenin.

Luego se constató que la diferencia en algunos elementos eran valores aceptables, razón para catalogar el sistema con éxito.

At the end of my civil engineering studies I had the opportunity to carry out a research project where the initiative arose to design an automated system for the structural calculation of reinforced concrete bearing walls of the cantilever type.
As a civil engineering student at that time I had little or no knowledge about programming, however it was not an impediment.
He got the advice of one and then another programmer but apparently there was a barrier between what he was trying to convey and what he expected him to understand.
After further research, we were able to meet with a third programmer where we could quickly identify the starting point, which would be a flowchart.
I will now present what was called SAM (automated wall system) as it was generated and the result obtained.

^{Cantilever-type wall elements.}

^{Procedures for the calculation of walls represented in the form of a flowchart, which was given to the programmer so that he could work with the agreed programming language}.

A flow chart was used to establish a calculation pattern following the detailed procedure in order to be able to use it as a guide in the development of the automated system. Also, the considerations for the design of walls, thrust calculations (Ka, Kp) and stability reviews were taken into account, in accordance with what is indicated in the standard covenin number 1756.

To design the automated system as a proposal for the calculation of the bearing wall, the programming language "java" will be implemented as a tool, which was assembling the calculation procedures oriented by the previously defined flowchart.

Screen of the programming language editor where the values and equations were introduced to perform all the tasks and commands necessary to execute the pre-dimensioning of the wall, equations for the calculation of the thrusts depending on the ground conditions, overturning, sliding and stresses on it in order to check that the safety factor values are within the design parameters.

^{Predimensioning comparison}

^{Check comparison}.

Once the output screen of the system was obtained by entering the data and analysis parameters, we proceeded to carry out a comparative exercise to evaluate the results obtained by the computerised system and those obtained manually, in accordance with the following procedure:

1. obtain the values of the friction angles of the soil to be contained and of the support of the wall, in order to find earth thrust coefficients (active and passive).
2. Knowing the height H of the wall, the dimensions of its elements must be determined.
3. Find the resultants of the earth thrusts and their points of application.
4. Calculate the magnitude of all gravity loads, due to the self-weight of the wall and the earth supported on the foot and heel.
5. Determinar la resultante R, producto de las cargas.
6. Calculate the overturning moment with respect to point I at the heel end.
7. Find the stabilising moment with respect to the same point I, with and without passive thrust.
8. Calculate the main steel of the wall shaft, placed vertically, next to the inner face, and at the foot of the wall, horizontally, next to the edge, respecting the minimum coverings according to the covenin standard.

The difference in some elements was then found to be acceptable values, which is why the system was successfully catalogued.
An automated structural calculation system for a specific type of wall, at very low cost and with reliable results for civil engineering and construction.
