Guidelines For The Eeri Seismic Design Competition, Kate Robinson Jun 2022

Guidelines For The Eeri Seismic Design Competition, Kate Robinson

Architectural Engineering

The Earthquake Engineering Research Institute (EERI) has been dedicated to exposing undergraduate students to the wide range of interdisciplinary subjects related to earthquake engineering through the Seismic Design Competition. In 2022, California Polytechnic State University, San Luis Obispo (Cal Poly) sent 14 students to Salt Lake City, Utah for the competition – to compete with 31 other teams who all tackled the competition problem statement uniquely. The 2022 team was tasked with the research, design, analysis, and construction of a new structure to be built in downtown Salt Lake City, with the goal of replicating the design sequence of real-world …


A Review Of Current Construction Guidelines To Inform The Design Of Rammed Earth Houses In Seismically Active Zones, David Thompson, Charles Augarde, Juan Pablo Osorio May 2022

A Review Of Current Construction Guidelines To Inform The Design Of Rammed Earth Houses In Seismically Active Zones, David Thompson, Charles Augarde, Juan Pablo Osorio

Articles

Sustainability in the materials we use for construction is a prime concern, focusing on reducing the embodied energy and carbon footprints of the materials used. The cement used in concrete products is responsible for a significant proportion of Man's CO2 emissions and its production requires substantial energy input, as do fired clay products. For this reason, products formed from unfired earthen materials are of increasing interest and the current challenges include devising means of robust design for strength and to address durability concerns. One form of earthen construction that employs an in-situ method is rammed earth, and it is a …


Analysis Of The Implementation Of Fluid Viscous Dampers In A Steel Special Moment Frame, Brad D. Weber Jun 2021

Analysis Of The Implementation Of Fluid Viscous Dampers In A Steel Special Moment Frame, Brad D. Weber

Architectural Engineering

This report examines the effects of adding fluid viscous dampers to a steel special moment frame through a series of analysis methods. Simple analysis procedures are first carried out and described, including a linear static procedure and a linear dynamic procedure. Then further analysis is carried out using a nonlinear dynamic analysis procedure. Multiple parameters are modified throughout the analysis processes to determine the impact on results and the data from all the analysis methods are compiled and used to demonstrate the overall impact of the use of fluid viscous dampers in a steel special moment frame.


Characteristics Of A Viscous Damper: Finding The Damping Coefficient, Roman Lara Iv, Tiffany Wang Jun 2019

Characteristics Of A Viscous Damper: Finding The Damping Coefficient, Roman Lara Iv, Tiffany Wang

Architectural Engineering

The authors of this report are undergraduate Architectural Engineering students at California Polytechnic State University in San Luis Obispo. This report documents the implementation, design, and experimentation of a damper with unknown properties. This experimentation data will be used to find the damping coefficient of a viscous damper alongside damping characteristics. Using knowledge from previous courses, this report focuses on dynamic responses through an assumed viscous damper. Through forced oscillatory motion testing with specified frequency and amplitude using the seismic shake table and equipment, compactDAQ instrumentation, and damper, values can be pulled from the data experimentation, which can be used …


Axial Testing Of Makeshift Buckling Restrained Braces, Daniel T. Item, Corey Huang Jun 2019

Axial Testing Of Makeshift Buckling Restrained Braces, Daniel T. Item, Corey Huang

Architectural Engineering

The testing of lateral force resisting systems is a concept that is very open to discussion and optimization. We seek to find the bounds of different materials as they act in a buckling restrained brace system in hopes of providing new methods of design for future structural engineering communities. By balancing budget, customization, and material availability we are able to determine what factors may benefit, or lack to benefit, the system at hand.


Retrofit Of Concrete Moment Frames With Masonry Infill In High Seismic Zones, Patricia Francis Pope, Madeleine Rasmussen, Zorana Tat Jun 2019

Retrofit Of Concrete Moment Frames With Masonry Infill In High Seismic Zones, Patricia Francis Pope, Madeleine Rasmussen, Zorana Tat

Architectural Engineering

Seismic events happen all throughout the world and each country has a slightly different way of handling the design of structures subjected to seismic forces. The goal of this project is to provide citizens of the Philippines with an effective way to retrofit their potentially unsafe buildings in the event of an earthquake. However, this retrofit manual will be able to help globally in other third world countries that have similar building techniques. In order to achieve this type of solution, we had to come up with options that took into account the lack of access to tools, materials, and …


A Cost-Effective Integral Bridge System With Precast Concrete I-Girders For Seismic Application, Justin R. Vander Werff, Rick Snyder, Sri Sritharan, Jay Holombo Sep 2015

A Cost-Effective Integral Bridge System With Precast Concrete I-Girders For Seismic Application, Justin R. Vander Werff, Rick Snyder, Sri Sritharan, Jay Holombo

Faculty Work Comprehensive List

To promote accelerated bridge construction in seismic regions, a large-scale experimental investigation was conducted to examine the seismic sufficiency of precast concrete I-girders in integral bridge super-structures. Such structures are not frequently used in high seismic regions due to lack of design guides and overly conservative design approaches. A half-scale,17.8 m (58.5 ft) long test unit modeling a portion of a prototype bridge incorporating a concrete column, ten I-shaped precast concrete girders, and an inverted-tee concrete cap beam was used to experimentally verify that precast concrete members employing accelerated construction techniques can be used in integral super-structures and provide excellent …


Predicting The Seismic Behavior Of The Dywidag Ductile Connector (Ddc) Precast Concrete System, Elizabeth Mary Kenyon Jul 2008

Predicting The Seismic Behavior Of The Dywidag Ductile Connector (Ddc) Precast Concrete System, Elizabeth Mary Kenyon

Master's Theses

Structural engineering is heavily dependent on the use of computers. When creating a building model using structural analysis software, it is required that the designer have an understanding of the system behavior and the modeling program capabilities.

Some engineers in the Southern California region are taking steps towards incorporating the Dywidag ductile connector (DDC) and super hybrid systems into building practice due to the advantages found in these systems’ construction methods and seismic performance.

As the DDC and super hybrid systems reach industry, the design engineer will need to model these systems using structural analysis programs. This report describes two …


Comparison Of Linear And Nonlinear Seismic Drift Histories For Midrise Steel Frames, K. Z. Truman, C. Pantelides, Richard A. Behr, Abdeldjelil Belarbi Jan 1996

Comparison Of Linear And Nonlinear Seismic Drift Histories For Midrise Steel Frames, K. Z. Truman, C. Pantelides, Richard A. Behr, Abdeldjelil Belarbi

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The linear and nonlinear seismic responses for two midrise office buildings of five- and 24-storeys were generated by two independent research groups using three commercial analysis packages, ABAQUS, SAP90 and DRAIN-2DX. The results indicate that a variability of up to 25% occurred between the independent research groups' seismic responses. Originally, these models and analyses were generated for the purpose of aiding in the development of load histories for the seismic testing of architectural glass at the University of Missouri-Rolla. The independent researchers were provided with the same structures, accelerograms and basic modelling assumptions and were directed to perform both linear …
