The Go-To for concrete slab and foundation design

Economically design post-tensioned and reinforced concrete floors

what is ram concept?

RAM Concept is structural software for the design of post-tensioned and reinforced concrete floors including slabs, mats, and rafts. It provides exceptional visibility into compliance, efficiency, and practicality. Design floors and foundations reliably and efficiently, saving time and money, and overcoming the most common concerns you face as a designer. RAM Concept allows you to easily design complex floor geometries and incorporate changes with ease using powerful task automation and clearly organized output.

Powerful design task automation for concrete floors and foundations

Design post-tensioned and reinforced concrete floors and foundations efficiently and incorporate changes with powerful task automation. RAM Concept is the ultimate solution for concrete slabs, mats, and rafts. It empowers you to design floor systems cost-effectively, with exceptional visibility into the compliance, efficiency, and practicality of the design. The design work in RAM Concept can seamlessly extend into the rest of a project for building information modeling, documentation, and collaboration with other structural designers due to its ability to interoperate with other engineering applications and formats. RAM Concept can be used on reinforced, and conventionally reinforced concrete projects. Plus, benefit from post-tension capabilities.

Design and analyze slabs

Automate time-consuming tasks such as the layout of tendons, design spans, and column and middle strips. Quickly rework floors when you need to make geometric revisions. Eliminate tedious manual iterations with the cloud-based post-tensioned slab optimization feature in order to reduce total tendon, reinforcement, and studded shear reinforcement costs.

Analyze long-term slab deflections and perform load history analysis to calculate for deflections with accurate consideration of time-dependent material behavior, cracking, and load history. Easily consider the effects of cracking, creep, shrinkage, tension stiffening, and load sequence.

Model tendons more realistically

Model banded, distributed, or arbitrary tendons with virtually any profile in their true three-dimensional positions. Get a better understanding of the effects of tendons on the slab with tendon loading analyses that consider full 3D hyperstatic (secondary) effects, including restraint from shear walls and stiff columns.

Perform accurate punching shear analysis

Check punching shear capacity for any slab geometry and reinforce columns below slabs and at transfer columns. Simplify real punching geometry into standard interior, edge, and corner conditions. Automatically design studded shear reinforcement (studrails) to save days of design time.
