Elastic settlements under linear surface pressures on rectangular areas

Abstract

SUMMARYThis paper presents the practical closed-form solutions for elastic settlement under the linear full-contact pressures on rectangular areas resting upon an elastic mass. The linear pressure distribution is mostly assumed in practice for the rectangular footing having biaxial bending. The equations presented here are determined by evaluating the integration of Steinbrenner's strain approximation based on the stress solutions from the Boussinesq equations. The presented formulae are validated to be used for the elastic settlement under any point of linear full-contact loading, triangular and embankment types of pressure cases. In this respect, it represents a significant step forward in the understanding of elastic settlement and rotation under the practical loading cases. The presented solutions are concise and easy to use. The numerical examples are demonstrated and the resulting influence factors in graphical forms are presented for their practical use especially in the elastic settlement calculations of rectangular footing subjected to the biaxial bending.

Correlación en Costos De Un Diseño De Una Cimentación Superficial Rígida Y Flexible Considerando La Consolidación Unidimensional

“…223). Las soluciones de Boussinesq se utilizan ampliamente en la práctica para todos los tipos de masas de suelo para obtener el aumento de la tensión vertical de las cargas de cimentación, representa un importante paso en la comprensión del asentamiento elástico (Algin & Algın, 2009). En la presente investigación está considerando una edificación de 06 niveles donde la cimentación está constituida por una losa de hormigón armado cuya distribución de esfuerzos bajo una superficie rectangular uniformemente cargada por Boussinesq considera la distribución de esfuerzos verticales en un punto a una profundidad debajo del cimiento.…”
