Teaching The Equivalent Rectangular Stress Block, Anahid Behrouzi, J. Chris Carroll, Ben Dymond

Architectural Engineering

The equivalent rectangular stress block is the basis for determining the flexural strength of reinforced concrete members. Instructors commonly present the concept in two dimensions, contrary to its three-dimensional nature. Unfortunately, this can be particularly difficult for students to understand and visualize, especially for students with visual learning style preferences. This paper presents an overview of the equivalent rectangular stress block, select active learning methods, and four specific examples used by the authors to introduce the equivalent rectangular stress block in an undergraduate reinforced concrete design course. The first method focuses on understanding the terms associated with the equivalent rectangular …

Active And Visual Methods For Teaching Nonrectangular Reinforced Concrete Beams, Anahid Behrouzi, J.Chris Carroll, Karl F. Meyer

Architectural Engineering

Nonrectangular cross sections are a common occurrence in reinforced concrete design typically taking the form of flanged beam sections, circular columns, and square or rectangular columns subject to biaxial bending. Instructors typically introduce the theory behind nonrectangular beams using two-dimensional sketches of flanged sections. Students can struggle to visualize the examples when presented in two dimensions; deciphering the multiple resultant compressive forces and their corresponding moment arms are particularly difficult. This paper presents an overview of nonrectangular beam theory and select active learning methods along with three specific examples used by the authors to teach nonrectangular beams in an undergraduate …

Wood Diaphragm Deflections. Part I: Generalizing Standard Equations Using Mechanicsbased Derivations For Panel Construction, John W. Lawson, Scott Breneman, Marco Lo Ricco

Architectural Engineering

Horizontal wood diaphragm systems, whether decked with conventional or mass timber panels, transfer wind and seismic loads to vertical elements of the lateral force-resisting system (LFRS), in flexible, rigid, or semi-rigid fashion. Characterizing and calculating the resulting diaphragm deflections determines the distribution of forces to critically loaded components and a significant portion of lateral building translations and rotations. Deflection equations for sheathed wood structural panel (WSP) diaphragms are well established in U.S. design standards in a 4-term expression that models flexural, shear, and fastener-slip deformations and its full derivation using principles of mechanics is provided herein. Derivations of similar equations …

Wood Diaphragm Deflections. Part Ii: Implementing A Unified Approach For Current Clt And Wsp Practice, John Lawson

Architectural Engineering

Horizontal wood diaphragm systems, whether decked with conventional or mass timber panels, transfer wind and seismic loads to vertical elements of the lateral force-resisting system (LFRS), in flexible, rigid, or semi-rigid fashion. Characterizing and calculating the resulting diaphragm deflections determines the distribution of forces to critically loaded components and a significant portion of lateral building translations and rotations. Deflection equations for sheathed wood structural panel (WSP) diaphragms are well established in U.S. design standards in a 4-term expression that models flexural, shear, and fastener-slip deformations, but similar equations for cross-laminated timber (CLT) diaphragms have yet to unfold, despite growing industry …

Physical And Digital Models For Timber Design And Analysis Courses, Paulina Robles, Gabrielle Rose Favro, Anahid Behrouzi, Abby Lentz

Architectural Engineering

Among structural engineering education research, there is a limited number of studies on interactive learning tools and activities specifically for the timber design classroom to assist students in visualizing material behavior, vertical and lateral load paths, and construction sequence. Timber design courses within the undergraduate program in the Architectural Engineering department at California Polytechnic State University in San Luis Obispo (Cal Poly), place an emphasis on seismic and wind design. Therefore, the proposed learning tools and activities are intended to pair with an introduction to concepts in the American Wood Council’s National Design Specifications (NDS) and Special Design Provisions for …

The Center For Centering Dome, Olek Piechaczek, Ryan M. Scharf

Architectural Engineering

The Center for Centering seeks to create a large-scale healing center, conducive to individual centering of the mind and body. This mobile installation provides a relaxing, enclosed space while still maintaining a connection to the outdoors. The clients liked the idea of having a pop-up installation that could be easily set up as a touring display. With a deadline for installation looming in June 2022, a team of students had five months to design and manufacture the structure.

In winter 2022, the students developed custom geometry to minimize the number of individual parts and built a ¼ scale model of …

The Leaf For Leaning Pine Arboretum, Maria Boyle, Shelby Holmquist, Andrew Duong

Architectural Engineering

The goal of this ARCE 415 senior project course was to create a shade structure that could be incorporated into The Leaning Pine Arboretum, located on campus at Cal Poly, San Luis Obispo. From start to finish, these three ARCE students took on the role of form-finders to form-testers to form-makers. We are putting the "architectural" back in architectural engineering as we reclaim the historical tradition of the engineer as the form finder. In many of our design labs we focused primarily on sizing members and analysis, just using a structure that the architect already had established. In this one-of-a-kind …

Investigation Of Natural Pozzolans: Analyzing The Practicality Of Natural Pozzolans As A Partial Substitute For Cement In Grout Production, Jadyn I. Breien, Andrew J. Baro, Logan T. Marino

Architectural Engineering

This senior project aims to investigate whether natural pozzolans are more sustainable than fly ash and a sufficient substitute for cement in the production of grout. By following the intent of the ASTM (American Society of Testing and Materials) standards, a conclusion will be made to determine if natural pozzolans can contribute comparable strength in compression. The objective is to prove that natural pozzolans should be utilized in the production of grout rather than alternatives such as fly ash because it can provide similar strength while being more economical and more sustainable.

Precious Plastics - Plastic Brick Machine Fabrication, Timothy Ukaobasi Kanu, Evi Paraskevi Troulis

Architectural Engineering

The goal of this research is to determine the structural parameters of the recycled plastic polypropylene when molded into bricks resembling CMU blocks. To accomplish this, three mechanisms had to be assembled: the shredder, the injector, and the 1x1 mold. A tensile and compression test were to be performed on the plastic brick, and the values would be used to compare the tensile and compressive strength of PP plastic bricks, as well as their modulus of elasticity and stress vs. Strain performance. These values would be analyzed to determine whether it would be feasible to build an entire plastic wall. …
