Influence of structural and soil parameters on Mat deflection

The present study was carried out to investigate the deflection characteristics of mat foundation for structural and soil parameters. The gap in knowledge about mat deflection characteristics brings some uncertainty in analysis of mat foundation and may result in its uneconomical design or unsafe design. For economy in design of mat with service core requires comprehensive understanding of the influence of it on mat. This work involved an extensive investigation of structural parameters effect on deflection of mat foundation using Finite Element Program SAFE V8. A comparative study has been made among some critical positions of the mat foundation using finite element methods in order to perceive the influence of different parameters that assist to understand the practical safety limit of the design characteristics. As only rigid frame structure with gravity and lateral load cases are considered here for the present work, further scope of the study maybe based on other types of structural system and mathematical modeling of mat response.
