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.

The team was provided a set of architectural drawings and a 3D architectural Revit model of Carson Headquarters in Omaha, Nebraska. The team was tasked with the creation of a complete structural design as well as a discussion of integration of other building design disciplines.

Modal Analysis Of Cal Poly’S Kennedy Library Using Computational Modeling, Joseph Mangan

Architectural Engineering

This project determines the modal parameters of the Robert E. Kennedy Library at Cal Poly, San Luis Obispo using ETABS. Similar analyses on the building have been performed in the past by other Architectural Engineering students. The recent renovation of the library which included a seismic retrofit provides the opportunity to understand how the modal response of concrete structures can be influenced by retrofit practices. This project provides insight into how computational modeling can be used to accurately represent real conditions, and how isolated changes from the retrofit affect the structure’s modal response.
