Overview

RAM Concept is a software application for the structural analysis and design of conventionally reinforced and post-tensioned concrete floors, mats, and rafts. RAM Concept contains an advanced feature set that allows for the design of a wide variety of floor systems including post-tensioned, reinforced concrete and hybrid systems, elevated slabs and mat/raft foundations, one-way slabs, two-way slabs, beams, and joist systems. Here's an overview of RAM Concept's key capabilities:

Complete modeling of the floor as physical objects: slabs, beams, walls, columns, openings, penetrations, etc., with the option to trace over a CAD background.
Option to create design objects (such as design spans and strips, and studded shear reinforcement) either manually or by intelligent program automation.
Organization of user interface by layers, much like a CAD program. This allows easy access to the large amount of information in the model.
Placement of reinforcement either manually or by automatic program selection, with the option to 'freeze' program reinforcement.
Tendon placement tools that allow the post-tensioning or prestressing in even large, complicated floors to be quickly established and refined.
3D finite element analysis of the structure, with rationalization into resultants for easy processing of results by the designer.
Exhaustive design capabilities including consideration of short and long term states, service and strength criteria, punching shear design, vibration due to walking, and advanced deflection calculations using load history.
2D and 3D plots of virtually any possible response quantity.
Creation of CAD file from reinforcing or post-tensioning plans in RAM Concept.
Integrate RAM Concept models with RAM Structural System, STAAD.Pro, or STAAD(X) to analyze and design the remainder of the structure for full gravity load takedown and systematic lateral loads.
