ACSAHE

A bit of
context...

The primary objective in the field of Structural Engineering is to design structures capable of resisting external loads—whether natural or anthropogenic forces—while efficiently, stably, and safely transmitting them to the foundation throughout their intended lifespan. In linear members such as beams or columns, these external loads are translated into internal section forces that the members must resist. The most common internal forces are Axial Force and Bending Moment, but determining their limits can be a complex task.
This is precisely the challenge that ACSAHE addresses.

A solution
for civil engineers

The determination of the strength of structural concrete members (reinforced or prestressed) subjected to Bending Moments and Axial Forces, requires solving non-linear equations, making hand calculations considerably complex.
As a consequence, Biaxial Bending – Axial Force Interaction Diagrams have been extensively used as a practical tool in the industry. In these diagrams, the axes represent the mentioned forces, and a contour of safe M, N combinations is depicted.

Interaction Diagrams normally limit themselves to particularly conventional cases (f.e. rectangular geometries, symmetric distribution of reinforcements, etc.), which is useful but does not allow for optimal designs or exploring the full potential of the materials used.

THE MISSION

ACSAHE generates interaction diagrams of combined axial-force/biaxial-bending for structural concrete sections under ACI 318-19(22)’s Chapter 22 hypothesis. The tool offers users complete flexibility to explore and analyze all cross-section possibilities, including those with prestressed reinforcement.
