RAMP: resilient construction through concrete 3D printing.

RAMP connects housing resilience, computational design, robotic fabrication, experimental testing, and numerical modeling to investigate high-performance 3D-printed concrete wall systems.

The research challenge

How can printed walls perform under disaster demands?

Concrete 3D printing makes it possible to vary internal wall geometry, material placement, and fabrication strategies. RAMP investigates how those design choices influence printability, structural continuity, damage, and performance under windborne-debris impacts.

The broader goal is to develop experimental evidence and validated digital models that can inform future studies of disaster-resilient printed housing systems.

Research workflow

Design. Print. Test. Model.

The project combines physical and computational methods so each stage can inform the next.

01

Computational design

Wall profiles and fabrication toolpaths are developed through parametric modeling in Rhino and Grasshopper.

02

Robotic fabrication

Material flow and accelerator delivery are checked before full wall profiles and companion specimens are printed and cured.

03

Impact testing

Planned experiments at Texas Tech’s National Wind Institute examine wall response across impact speeds and locations.

04

Digital modeling

Three-dimensional documentation and finite-element analysis support model validation and expanded impact scenarios.

Collaborative team

Engineering resilience meets architectural robotics.

This HUD-supported initiative pairs CECREH’s housing-resilience expertise with the Hi-DARS Lab’s work in computational design, emerging materials, and robotic fabrication. Experimental testing at Texas Tech’s National Wind Institute extends the collaboration into hazard-performance evaluation.
