Xenaform Algorithm, Alden Ulysses Quandt

Architectural Engineering

This project develops a computer-generated form-finding process for XenaForms, a discrete folded-plate shell system made from rigid triangular panels and hinge-like edge connections. Using Blender and Python, the workflow generates an initial top-down triangular strip, expands it into a fuller shell through stability-guided growth, checks the resulting geometry against a local stability rule, and culls unstable or erroneous elements. The algorithm translates XenaForm stability principles into a usable design tool while also accounting for constructability through sheet-size constraints and geometric collision checks. The result is a Blender-based workflow that can rapidly produce stable, varied XenaForm models for architectural, sculptural, and …

Assessing Video Game Pedagogy For Civil Engineering Education And K-12 Stem Engagement, Jillian Codron, Anahid A. Behrouzi

Architectural Engineering

Traditional civil engineering education is often structured around a “theory before practice” model, where students first learn concepts in lecture and then confirm them in a laboratory setting.

Xenaforms: Reinforcing Kinematic Stability Through Rigid Connections, Katherine G. Thies

Architectural Engineering

XenaForms combine rigid planes and straight lines with the fluidity of structural origami to create beautiful, organic folded plate structures. Unlike many conventional structures, folded plate systems derive their stability from the interaction between connected panels, creating the appearance of a single continuous sheet of material. The XenaForm uses structural origami and triangulation to create stable points at the apex of two non-colinear triangles. While it is mathematically true that no moment needs to be transferred across the seam between panels in order to have a stable structure, allowing some moment capacity greatly helps during construction. Specifically, these stiff connections …

Mineral King Cabin Roof Rennovation, Leilani G. Lau

Architectural Engineering

This project explored performance-based design by analyzing and redesigning the roof for a cabin built in the 1950s and located in Mineral King Valley in the Sierra Nevada Mountains, California. The Sierra Nevada Mountains experience heavy amounts of snow during the winter season. In the winter, the cabin is unoccupied, so the performance objective was collapse prevention, rather than life safety. Since the performance objective focused on collapse prevention at a time when the building was unoccupied, the probability of failure did not need to be low, so safety factors were omitted. This approach required deeper understanding of the code …

Performance Of Reinforced Concrete Wall With Discrete Frp Boundary Element Retrofit, Katelyn Lowry, Roger Biddle, Peter Laursen, Anahid A. Behrouzi, Cole Mcdaniel

Architectural Engineering

This paper presents experimental results for a lightly reinforced concrete (LRC) shear wall retrofitted with discrete fiber-reinforced polymer (FRP) strips at the boundary zones. The performance of this wall was evaluated through cyclic lateral load testing and compared with a wall retrofitted with continuous FRP at the boundary zones (Duong et al., 2024). Test results showed that the wall retrofitted with discrete strips exhibited a flexural tensile failure characterized by wide flexural cracks confined between FRP strips and rebar fracture at high drifts, while maintaining displacement compatibility and axial load capacity beyond strength degradation. Compared to the continuous FRP retrofit, …

Cementing Co2 Into C-S-H: A Step Toward Carbon Neutrality, Or A Step In The Wrong Direction?, John Reilly Benn, Tahne Larson

Architectural Engineering

As greenhouse gas emissions continue to rise, many in the construction industry are looking for sustainable solutions to reduce its carbon footprint. One of the biggest contributors to atmospheric CO2 comes from cement production. In 2023, researchers at MIT explored ways to enhance concrete’s natural ability to act as a carbon sink. Concrete does this unassisted through a chemical reaction called carbonation, by which atmospheric carbon bonds to key components in cement. The researchers at MIT proposed a process of early-stage forced carbonation, which can be induced by the addition of NaHCO3 into a standard concrete mix. Sodium bicarbonate, or …

Concrete Mix Designs With Shrinkage Reducing Admixture, Beau Usry, Julio Munoz Tanaka

Architectural Engineering

The goal of this project was to explore how shrinkage-reducing admixtures (SRAs) affect the strength and overall performance of concrete. While SRAs are typically used to help reduce shrinkage and cracking, it is less common to see how they might affect compressive strength directly. To test this, three different concrete mixes were made: a control mix with no admixture, one mix with 1% SRA, and another with 3% SRA. The idea was to compare how each mix performed under the same testing conditions.
