Development of a Mechanical Seismic Simulation Apparatus for College Engineering Education

Description

The School of Sustainable Engineering and the Built Environment (SSEBE) used to have a shake table where FSE 100 professors would use students' model structures to demonstrate how failure occurs

The School of Sustainable Engineering and the Built Environment (SSEBE) used to have a shake table where FSE 100 professors would use students' model structures to demonstrate how failure occurs during an earthquake. The SSEBE has wanted to build a shake table ever since the original table was no longer available to them. My creative project is to design and build a shake table for FSE 100 use. This paper will go through the steps I took to design and construct my shake table as well as suggestions to anyone else who would want to build a shake table. The design of the shake table that was constructed was modeled after Quanser's Shake Table II. The pieces from the shake table were purchased from McMaster-Carr and was assembled at the TechShop in Chandler, Arizona. An educational component was added to this project to go along with the shake table. The project will be for the use of a FSE 100 classes. This project is very similar to the American Society of Civil Engineers, Pacific Southwest Conference's seismic competition. The main difference is that FSE 100 students will not be making a thirty story model but only a five story model. This shake table will make Arizona State University's engineering program competitive with other top universities that use and implement shake table analysis in their civil engineering courses.

The Barrett creative project in residential structural design serves as the culmination of my most meaningful undergraduate experiences and interests. I previously interned for D.R. Horton, a home builder, and spent a significant amount of time on the development sites and in the engineering management office. This experience sparked a curiosity in the design of wood frames for homes and the residential industry as a whole. Since then, I have also had the opportunity to intern for Felten Group, an architecture, engineering, and forensics firm specializing in residential work. A residential roof structure is designed following the American Society of Civil Engineer's Minimum Design Loads for Buildings and Other Structures design code, in addition to the National Design Standards for Wood Construction manual. Although the sub discipline of wooden structural design can often be disregarded as the simplest type of analysis, I believe that it is a key component of an education in structural engineering. Like all aspects of civil engineering, the design of a house is composed of many interconnected systems, which include the balance of structural integrity and cost, functionality and aesthetics, and light and space. For my creative project, I took these ideas into account when designing both the floor plan and roof structure of the house using Revit and RISA, respectively. Well-rounded engineers are not only technically competent, but they also understand the social dimensions of a problem and how all the systems work together. The project focuses on creating a cohesive representation of a structure as a whole and how the individual frames, trusses, and beams interact with one another using RISA, a structural analysis program. With RISA's 3D interface, I have a better understanding of how more complex structures behave, which I have not gained from my 2D perspective in classes. RISA is used to calculate support reactions and the deflections of the trusses, which are checked against the bearing capacities of the supports and deflection design criteria to ensure a safe design. Concepts such as tributary area, truss connections, and the behavior of girder systems are also explored through the process.

Mexico City: Earthquake Dynamics of Structures

Description

The 8.1 magnitude earthquake that struck Mexico City in 1985 left 10,000 people dead, and over 400 buildings collapsed. The extent of the damage left behind by this powerful quake

The 8.1 magnitude earthquake that struck Mexico City in 1985 left 10,000 people dead, and over 400 buildings collapsed. The extent of the damage left behind by this powerful quake has been extensively studied to make improvements to engineering and architectural practices in earthquake-prone areas of the world. Thirty-two years later, on the exact anniversary of the devastating earthquake, Mexico City was once again jolted by a 7.1 magnitude earthquake. Although still significant, the 2017 earthquake collapsed only about a tenth of the buildings collapsed by the 1985 Earthquake, and in turn resulted in a lower death toll. Even though these earthquakes struck in the same seismic region, their effects were vastly different. This thesis completes a comparison between the two earthquakes focusing on the structural impacts including background on Mexico City's unique geology, basic concepts necessary to understand the response of structures to earthquake excitation, and structural failure modes observed in both earthquakes. The thesis will also discuss the earthquake's fundamental differences that led to the discrepancy in structural damage and ultimately in lower death tolls. Of those discussed, is the types of buildings that were targeted and collapsed. In 1985, buildings with 6 or more floors had the highest damage category. Resonance frequencies of these buildings were similar to the resonance frequencies of the subsoil, leading to amplified oscillations, and ultimately in failure. The 2017 earthquake did not have as much distance from the epicenter for the high frequency seismic waves to be absorbed. In contrast, the shorter, faster waves that reached the capital affected smaller buildings, and spared most tall buildings.

This Barrett creative project includes the structural design of a coffee shop using recycled shipping containers in Phoenix, Arizona. Repurposing old shipping containers into commercial and residential buildings has become more popular. Even here in Arizona, buildings have already integrated shipping containers into their design. Shipping containers add a unique character to the architectural design of the building and at the same time cut costs of construction due to their low prices. With using the shipping containers as building materials, there is a positive impact on the use of the structures in builds. The uniqueness of using shipping containers is what sparked my interest to design a shipping container coffee shop. For my creative project, I designed the coffee shop using the already structurally sound core of the shipping container to my advantage. However, when adding modifications to the structure, the materials of the structure were analyzed to ensure the design could take the modifications. I have taken my love for structural design, the environment, and coffee and brought it to life. Through this project, I have a better understanding of how much thought goes into designing a building and have a deeper understanding of the codes that structural engineers must follow to design and analyze buildings.

Evolution of Women in Engineering

Women have evolved in the engineering profession over the decades. However, there is still a lot more room for female presence in the industry as women currently make up about 12-15% of working engineers. Based on many studies and surveys, it is clear that female confidence in their own performance and a feeling of belonging in the industry has evolved for the better. The studies and surveys also show that women still lack a certain confidence to get their engineering degree and then to pursue a career in engineering once they receive their degree. Research shows that the main cause for this is due to the stereotype that engineering is a masculine profession. Men and women both have this mindset because it has become a societal norm that most people go along with and do not even realize it. Unfortunately, it is very hard to overcome and change a societal norm, therefore, something needs to be done in order to fix this mindset. (Crawford). Based on studies and research, there are many ways the stereotype is being combatted. Social media has become a huge component in advocating for female engineers. Men and women are helping to fight the status quo by supporting female engineers and lobbying against people who think women do not belong in the industry. Industry professionals are teaming up with schools to figure out ways to make STEM programs more exciting for all young kids, but especially girls. They are also working to provide more mentors and role models for young girls in order to cheer them on and make them more confident in their abilities when learning and applying the STEM curriculum, as studies have proven that providing young girls with mentors can really help foster more female engineers in the long run. (Crawford). With all of the positive support and promotions of female engineers in the past few years, it is evident that women can certainly progress at a much faster pace than in previous decades.

Ahwatukee Foothills Village Final Residential Structural Report

Description

This project report contains the design of a low-cost structural model of a residential structure in the City of Phoenix, AZ. The structural unit will be part of a residential

This project report contains the design of a low-cost structural model of a residential structure in the City of Phoenix, AZ. The structural unit will be part of a residential area in Ahwatukee Foothills Village located just south of South Mountain. The residential structure is 3600 square feet and consists of three bedrooms (including the master bedroom), two bathrooms (including the master bathroom), a 2-car garage, laundry room, kitchen, dining room, and a living room. There are two elevation options (A & B) for the roof framing plan. Elevation A includes a straight forward truss package consisting of two truss designs with no hip or girder trusses. Elevation B includes a more complex truss package which includes girder trusses, hip trusses, and corner jacks. Within both elevations, the trusses run perpendicular to the ridge of the structure as displayed in the Architectural Floor Plan (see Figure 4) with the exception of the hip trusses and corner jacks in Elevation B.

The design objective is to meet all safety specifications while minimizing the total cost of members and member connections. The design also aims to streamline the construction time and resources by using standard member cross section dimensions. This residential building report is carried out in accordance with the City of Phoenix standards and follows the ASCE7-10 code for the dead and live load combinations and wind pressures. This report also references the National Design Specifications (NDS) 2005 for the column design. HT Consulting Group is excited to create a safe and sustainable development for the residents within Ahwatukee Foothills Village.

An existing house is outdated and in need of a renovation. The kitchen, living room, bar and dining room are currently all closed off from one another creating four separate spaces. The goal is to recreate the main floor into an open concept space, that is great for entertaining, and being with family and friends. This Thesis/Creative Project deals in the area of structural redesign, aesthetics, client relations and budget tracking. To do this effectively, Revit, AutoCAD, RISA 3D and Excel will all be used to complete various elements of the project. In order to open the space a structural analysis needs to be done to ensure the structural integrity of the home remains solid. If structural walls are being removed the forces being exerted on those walls will need to be redistributed. This will require a redesign of the structural members to ensure the forces are supported. Once the walls are down the area can be redesigned to ensure function and usability. Every inch of the space needs to be optimized to ensure the most efficient use of space. The storage will also need to be taken into consideration because there will be storage loss when removing walls. The space will need to look aesthetically pleasing and keep in theme with the country cabin feel of the home. The Client’s will be involved in every step of the process to ensure they are satisfied with the varying design. While redesigning the area there is a strict budget that was set by the Clients, and every step of the designing process needs to take into consideration the cost. Once the successful completion of the project is accomplished, the Clients, will have the ability to take the plans and complete the renovation on the house.
