Title: Engineers without borders & CIEST student concrete clinic

Year: 2024

Participants: Engineers without borders, CIEST

Summary:

In the spring of 2024 CIEST hosted a student tutorial for the non-profit, Engineers without Borders or EWB. The tutorial was aimed at giving students experience making concrete before a trip to Nepal. The following video contains some of this process https://www.youtube.com/shorts/0TH0gq_Hia4. The non-profit, EWB, is an organization that goes to regions with limited access to building materials and creates infrastructure for underdeveloped towns and villages. We at CIEST were exited to be a part of Engineers without Border's mission, and would like to give special thanks to Rebecca Komarek, and Cayden Stratford for their help organizing the clinic.

Shell Mechanical Engineering Senior Design Team

Shell Mechanical Engineering Senior Design Team Anonymous (not verified) Thu, 03/26/2020 - 20:16

Year: 2019-2020

Participants: Joe Borgerding, Isaiah Brooks, Austin Maes, Nestor Montejo, Andrew Townsend, Grant Stewart

Summary: A Mechanical Engineering Senior Design team, sponsored by Shell, worked with CIEST on their project throughout the 2019-20 academic year. The goal of the project was to design, manufacture, and test the vibration responses of different piping systems with and without mitigation methods applied. The piping systems included an expansion loop system and 90 degree bend system, and the mitigation consisted of fixed restraints. The systems were tested using CIEST’s large shake table. This hands on testing enabled their team to explore the effects of common mitigation techniques to better understand vibration as a phenomenon while gaining valuable experience with testing procedures and data processing.

AP Research: Mycelium and Seismic Performance

AP Research: Mycelium and Seismic Performance Anonymous (not verified) Thu, 03/26/2020 - 19:50

Year: 2020

Participants: Anna Broerman, Kaitlyn Gentert

Summary: Erie High School student Anna Broerman, accompanied by her teacher Kaitlyn Gentert, investigated the inclusion of mycelium in cement bricks to aid in seismic performance for her AP research project. Mycelium is derived from fungus-like bacteria, such as mushrooms, and has been shown to maintain its strength long after death, making it an interesting component for mix design. Anna compared results from compression and 4-point bending tests between bricks with and without mycelium fibers to characterize material properties using CIEST's 10-kip (45 kN) Instron UTM. Using mortar, she then constructed small structures, again with and without mycelium, mounted to CIEST's 4-kip (18 kN) shake table to see if the fibers provided a natural seismic resiliency. With special help from Dr. Jaroslav Hruby, the structures were taken through frequency sweeps where the eigenfrequency was isolated and then taken to failure with increasing steps in acceleration. This was a valuable hands-on experience for Anna and Mrs. Gentert. CIEST hopes to continue teaming up with local high schools to provide unique and unforgettable outreach experiences.

Summary: The CU Earthquake Engineering Research Institute (EERI) Seismic Design Team competed in Vancouver for 2019 competition. The students worked very hard, testing multiple protypes on the CIEST Labratory shake table to perfect their building. The expeiencial learning that comes from these types of events are incredible!

Rocky Mountain 2019 ASCE Conference Anonymous (not verified) Thu, 08/29/2019 - 13:06

Year: hosted 2019, held annually

Participants: American Society of Civil Engineers student chapter

Description: The CU ASCE student chapter hosted the ASCE Rocky Mountain Regional Conference in April 2019, which was attended by student ASCE chapters from Colorado, New Mexico, Utah, and Wyoming. There was large community envolvment, including many student volunteers and participants, industry, and staff support. The CIEST staff helped support the conference from the early developmental stage through the completion of the conference. The conference was a great way to celebrate the hard work of the conference comittee and the student competition teams from each school that worked so hard to compete.

Concrete Mixing and Testing Anonymous (not verified) Thu, 11/08/2018 - 10:41

Course: AREN 4830 - Sustainable Materials and Structures

Year: 2018

Participants: �鶹��Ժ and Graduate Teacher, Jay Arehart

Summary: �鶹��Ժ developed concrete mix designs optimized for strength, cost, and sustainability. They also employed a variety of strategies to minimize the environmental impacts of their concretes such as using supplementary cementitious materials and recycled concrete aggregates. After designing their mixtures, the students mixed their concrete and cast cylinders that were testing for their ultimate compressive strength. The CIEST lab served as a resource for the students to learn about concrete mix designs and their environmental impacts.

CIEST served as a resource to students in AREN 4830 (Sustainable Materials and Structures) as they designed and tested concrete mixes and considered the variable environmental impacts of their chosen materials.
