“…Para las figuras 2c, 2d y 2e, su principal aplicación es para cabezales que soportan una carga axial y dos momentos (dirección X y Y). La ecuación general para obtener el esfuerzo generado en cualquier parte por el suelo sobre las zapatas apoyadas en estratos superficiales (cimentación superficial o poco profundas) sujetas a flexión biaxial es (Gere & Goodo, 2009;López-Chavarría et al, 2017;Luévanos-Rojas et al, 2017;Velázquez-Santillán et al, 2018):…”

Este documento muestra un modelo optimizado para cabezales o zapatas rectangulares apoyadas sobre un grupo de pilotes, con el fin de obtener el área de la superficie mínima en planta que soporta una carga axial y dos momentos en dirección del eje X y Y debido a una columna. Este modelo asume que los cabezales son perfectamente rígidos y los pilotes están articulados en la unión de los cabezales con los pilotes y, por lo tanto, los pilotes transmiten solamente carga vertical. La metodología normalmente utilizada para obtener el área de la superficie en planta de los cabezales se propone de acuerdo con la distribución de los pilotes, tomando en cuenta las especificaciones marcadas por los códigos de construcción. También, cinco tipos de cabezales apoyadas sobre un grupo formado por dos, tres, cuatro, cinco y seis pilotes se muestran para demostrar la exactitud del modelo presentado en este documento.

López-Chavarría et al [22] investigated the optimal dimensioning for the corner combined footings. Luévanos-Rojas et al [23] investigated the optimal design for rectangular isolated footings using the real soil pressure.…”

This paper shows a general model of rectangular footings to obtain the soil minimum contact area (optimal surface) that support from 1 to n columns aligned on a longitudinal axis. The proposed model considers that the soil pressure varies linearly. The recently published models have been presented individually to obtain the soil contact area for rectangular isolated footings, rectangular combined footings that support two columns, these models present the equations, but it is not guaranteed to be the minimum area. The present research complies with the models mentioned above and can be applied to footings that support 3 or more columns, and also the minimum area is guaranteed. Also, numerical problems are shown the soil minimum contact surface for rectangular isolated footings, and rectangular combined footings that support two and three columns (unrestricted on its sides, one side restricted and two opposite sides restricted).

“…Chavarria et al . [5] have shown the optimal dimensioning for combined footings to meet the contact surface on the soil, the bending moment about X and Z axes in each column developed due to axial load. The EMETL [6] provides the standards for allowable spans, clearance, live load conditions based on the diameter of the pipe and the standard pipe-bridge load-application criteria.…”

Pipe bridges are structures that play an indispensable role in chemical and oil plants. They support cable trays or pipe-carrying material. This study aims to identify the ideal configuration of a pipe bridge through the comparative study of girders with drop hanger and truss arrangements for three different spans. The most efficient arrangement for each span was suitably identified. Through the analysis carried out, it was then identified that the Girder arrangement is suitable for smaller spans such as 15 meters; while the truss arrangement was preferable for longer spans.
