Flat Slab and Raft Design with Slab Patch Panels

Summary

Advancing Slab and Foundation Design with ProtaStructure

Designing safe and efficient structural systems requires advanced tools and methods to optimize material use and ensure compliance with standards. ProtaStructure Suite provides a comprehensive range of features for designing beam-slabs, flat slabs, rib/waffle slabs, and raft foundation systems. These tools empower engineers to deliver economical and practical solutions tailored to project needs.

Key Features for Slab and Foundation Design

ProtaStructure employs two main methodologies for slab and foundation design:

  1. Finite Element Method (FEM): Used for analyzing rib/waffle slabs, flat slabs, and raft foundations, FEM offers precise results by modeling real-world behavior under applied loads.
  2. Moment Coefficient Method: Utilized for beam-slab systems, this method provides a quick and reliable approach for simpler designs.

By integrating these methods, ProtaStructure ensures that engineers can achieve optimal performance and efficiency across a variety of slab and foundation systems.
