Rigid footing and flexible footing
WebExplanation: Contact Pressure. Loads from the structure are transferred to the soil through the footing. As a reaction to it, soil exerts upward pressure on the bottom surface of the footing which is termed as contact pressure. For flexible footing: Contact pressure is uniform. For Rigid footing: Settlement is uniform. WebWhen treatign a structrue as rigid or flexible, a major consideration is the aspect of interest. For example, if you wish to find out the stresses on a building, the nthe foundation can be …

WebBtech in Bachelor of Technology in Civil Engineering & Civil Engineering, National Institute of Technology Silchar (Graduated 2003) 6 y. The main difference between rigid and flexible foundation is the rigidity of the footing. The rigid footing is assumed to be infinitely rigid … WebJul 21, 2014 · Most references state that the contact stress in cohesionless soil is concentrated at the footing center and is low at the footing edges. It cannot be done, according to the numerical analysis, except in two cases. Case 1 is the flexible footing, and it is not applicable because the designed footing is considered semi-rigid.
WebSM ...footing WebMar 30, 2024 · When a flexible footing is laid on the Cohesionless soil, the settlement at the center becomes minimum while at edges it is maximum which exact opposite case of the settlement of flexible footing over cohesive soil. 2). Under Rigid footing: For rigid footings resting on cohesive soils, the settlement is uniform but contact pressure varies. At ...
WebMay 2, 2005 · This approach is valid for infinitely rigid footings. Past experience has shown that the assumption of a linear pressure distribution is satisfactory for most footings; however, there are some cases in which a shallow foundation must be analyzed as a flexible structure, particularly if the footing is excessively long/wide and thin. WebIn this paper an elastic settlement analysis method for rigid rectangular footings applicable to both clays and sands is proposed. The proposed method is based on the concept of equivalent shape, where any rectangular footing is suitably replaced by a footing of elliptical shape; the conditions of equal area and equal perimeter are satisfied simultaneously. The …
