I built a tool in grasshopper that could analyze a concrete member's resistance to delamination in real time due to numerous parametric variables, such as pre-stressing force, radius of the member, and concrete strength. The tool gives engineers a sense of what design limits are possible in non-linear pre-stressed space. https://images.squarespace-cdn.com/content/v1/5a64f5f08a02c74bc460d658/1517095973289-1AL6WUEGTHV9MX833MV1/Screen+Shot+2018-01-21+at+3.31.02+PM.png Master's Work - Design of Steel Structures: Pedestrian Bridge For the capstone of my Design of Steel Structures at UC Berkeley, we organized into teams of four and designed a pedestrian bridge to link the East and West spans of the Bay Bridge. The site constraints called for a low-impact design on the natural landscape, and an iconic structure to help define the region. Our team wanted to keep views as open and stunning as possible for pedestrians experiencing the beauty of the Bay Area. https://images.squarespace-cdn.com/content/v1/5a64f5f08a02c74bc460d658/1516656396982-NZRZHPOIVS81KFQT8NKP/IMG_20180122_145102-2.jpg Master's Work For my Introduction to Making class at MIT, my teammates and I wanted to build a physical game we could play against a robot. We built a game like Pong, where you use paddles to try to knock a ball past the computer's "goal." I have included a video towards the bottom of this page. https://images.squarespace-cdn.com/content/v1/5a64f5f08a02c74bc460d658/1516635361486-DM607X62F6ZQJ9CEYKFU/Screen+Shot+2018-01-22+at+10.34.18+AM.png Master's Work During the Fall semester of 2017, our Structural Engineering master's cohort was organized into groups and tasked with designing a long-span roof over an existing courtyard on MIT campus. https://images.squarespace-cdn.com/content/v1/5a64f5f08a02c74bc460d658/1527387397492-78K0OARG9SWDIE87RPN9/IMG_20180520_124007.jpg Master's Work For our Design for Robotic Assembly course, we wanted to program our 6-axis robot to cut styrofoam blocks with a heated wire. Our hope was to cut geometries in a more accurate and faster method than a CNC mill. https://images.squarespace-cdn.com/content/v1/5a64f5f08a02c74bc460d658/1527468809710-KL4N3UKXSP96WAXF4ZWI/highrise_clean.jpg Master's Work For our design class, we were tasked with designing a high-rise mixed-use structure in the Hudson Yards site in New York City. https://images.squarespace-cdn.com/content/v1/5a64f5f08a02c74bc460d658/1516666357613-VL0EB1S9R1F46P5QKWIG/Screen+Shot+2017-11-14+at+12.59.19+AM.png Master's Work - Optimized Cantilever Topology optimization is a robust tool for structural design that can autonomously generate efficient forms within a given design domain by ascribing construction material to key locations of the structure while simultaneously removing it from underutilized areas. https://images.squarespace-cdn.com/content/v1/5a64f5f08a02c74bc460d658/1523227914970-3UANYM45KATBNMKGWLJL/IMG_9271.JPG Master's Work - Click on any image for the journal article discussing this research in detail. For my Master’s Thesis, I designed, fabricated, and tested plain concrete beams using topology optimization. To carry out the tests, we built a custom testing apparatus to deliver our atypical load conditions into our concrete specimens. https://images.squarespace-cdn.com/content/v1/5a64f5f08a02c74bc460d658/1519014015501-DYUA015DN0OL3FEJDG8Z/IMG_20180215_170225.jpg Master's Work - Click any image to access the journal article explaining this research. Topology optimization is an exciting tool for generating efficient structural design, yet there is little experimental confirmation of their efficacy in Civil Engineering applications. For my thesis, I fabricated and tested concrete beams designed with a stress-based topology optimization algorithm. https://www.jacksonjewett.com/favorite-papers daily 0.75 2022-06-05 https://images.squarespace-cdn.com/content/v1/5a64f5f08a02c74bc460d658/1516653184951-XQX72WPRUFE6U111COUC/fabric+form.JPG Favorite Papers - Fabric Forms: The Robotic Positioning of Fabric Formwork This is an inspiring paper by Ron Culver, Julia Koerner, and Joseph Sarafian that combines robotically-modulated digital fabrication methods with fabric-formed concrete. The paper begins here on page 107; the photo is borrowed from the publication. https://images.squarespace-cdn.com/content/v1/5a64f5f08a02c74bc460d658/1516654211751-SLOI9ZC22QM5KWXTIUBM/hammerhead.JPG Favorite Papers - Reinforced Concrete Force Visualization and Design Using Bilinear Truss-Continuum Topology Optimization This paper, more than any other, has shaped my thinking on my thesis. It combines continuum and truss topology optimization meshes to simulate the behavior of reinforced concrete. While I read it for the first time, all I could think was "how cool would it be to build one of these?" It was written by Andrew T. Gaynor, James K. Guest, and Christopher D. Moen, with whom my advisor Josephine V. Carstensen worked during her PhD. The full-length paper can be found here.     https://images.squarespace-cdn.com/content/v1/5a64f5f08a02c74bc460d658/1516653162929-YTE1DZ1E285Q401XSYHU/ICD.JPG Favorite Papers - ICD/ITKE Research Pavilion 2016-17; Photo borrowed from Roland Halbe I am a fan of almost everything they do at the Institute of Computational Design and Construction. This pavilion is particularly interesting for its extensive use of fiber composite materials, and the fact that they used a unmanned aerial drone for construction. Here is a link to the site, with an incredible video           https://images.squarespace-cdn.com/content/v1/5a64f5f08a02c74bc460d658/1516846984623-Z07N6SXKTMMQKOC17ZCB/Screen+Shot+2018-01-24+at+9.15.29+PM.png Favorite Papers - Scissor Mechanisms for Transformable Structures with Curved Shape The idea behind this is simple, elegant, and smart. The authors Etienne Bouleau and Gabriele Guscetti use scissor-mechanisms and kinetic amplification such that small modulation in the bridge creates large global deformations in the structure – and they actually built it! The paper is so cool.   https://images.squarespace-cdn.com/content/v1/5a64f5f08a02c74bc460d658/1516847394399-6G8JJFJHJJR5QOOMHNO0/Screen+Shot+2018-01-24+at+9.29.31+PM.png Favorite Papers - Behavior of Curved Post-Tensioned Concrete Structures without Through-Thickness Reinforcement I searched everywhere for a paper that discussed delamination failure due to post-tensioning in curved concrete members, and I finally found it here. The authors Jongkwon Choi and Trevor Hrynyk made this complex mechanics phenomenon comprehensible and interesting to read. https://images.squarespace-cdn.com/content/v1/5a64f5f08a02c74bc460d658/1516850868018-NB6V3MAVXS1BCJPM37LV/Screen+Shot+2018-01-24+at+9.08.14+PM.png Favorite Papers - Aleatory Construction Based on Jamming This is a cool paper that plays with the idea of reconstructable, reusable construction material. The self-confined arch picture just blows my mind, and related projects like the Rock Printer are invaluable experiments for the field of Structural Engineering. This particular paper was written by Kieran Murphy, Leah Roth and Heinrich Jaeger.   https://images.squarespace-cdn.com/content/v1/5a64f5f08a02c74bc460d658/1516850792845-5QX2MI3TNXOHJMWJJJD3/Screen+Shot+2018-01-24+at+9.08.40+PM.png Favorite Papers - CASTonCAST Shell Structures This amazing paper outlines a fabrication technique in which pieces of curved concrete are casted on top of one another, then bound together with post-tensioned cables. As an efficient and beautiful building technique, it is extremely interesting. The paper goes very good detail on how this model was built; it was written by Lluis Enrique and Joseph Schwartz https://images.squarespace-cdn.com/content/v1/5a64f5f08a02c74bc460d658/1551668198767-NHJHMP2K7JV4V1EB51SV/Screen+Shot+2019-03-03+at+9.55.56+PM.png Favorite Papers Topology-Optimized Design, Construction and Experimental Evaluation of Concrete Beams I would be remiss to not mention the publication of my first paper, which was accepted by Automation in Construction in January of 2019! It details the work I did with my advisor at MIT for my thesis, in which we tested two different optimization algorithms against one-another using concrete as the construction medium.

We found we could increase the strength of concrete by 25% using the same volume of material as a control specimen.

Researchers only printed the outer layer of the concrete, leaving the inside to be filled with rebar and poured concrete after an initial cure.
