Modeling Mat (Raft) Foundations (Flexible Method) in Autodesk Robot

Welcome to our tutorial on Modeling Mat (Raft) Foundations (Flexible Method) in Autodesk Robot. In this video, we'll show you how to model mat foundations using the flexible method in Autodesk Robot and how to analyze their behavior under different loads and supports. Whether you're an engineer, architect, or student, this video will help you understand the basics of mat foundation modeling and how to apply them to your projects. We'll cover topics such as modeling techniques, defining properties, and analyzing the results. We'll start by showing you how to create a new model and define the properties of the mat foundation, such as thickness, material, and reinforcement. We'll also cover how to define the soil properties and the boundary conditions. Next, we'll show you how to apply loads and supports to your mat foundation, such as self-weight, dead loads, and live loads. We'll also cover how to analyze the results, such as the settlement, stress distribution, and bearing capacity. By the end of this video, you'll have a better understanding of how to model mat foundations using the flexible method in Autodesk Robot and how to analyze their behavior under different loads and supports.

Also, let us assume that the Kz used in the software is calculated without factor of safety. The "simplistic equation" is: delta = F/K. Since the K is without a factor of safety, there are two approaches for this: Approach 1: calculate the "safe" "allowable" K by dividing by 3 (Factor of Safety). Then use it calculate the the settlement. (So we would need another model for this) Approach 2: realize that the soil is "too strong" and limit the deflection to 1/3 of the 0.025. HUGE THNX. It helps a lot. Current Video Ideas for the Future: LL Reduction in ACI/ASCE (vertical and horizontal) A possible way to model columns with pressure areas Deeper dive into slab reinforcement.
