The Automation Of Bim For Compliance Checking: A Visual Programming Approach, Jonathan Reinhardt, Malachy Mathews

Conference papers

A study by FIATECH confirmed that human interpretation causes inconsistencies in applying building compliance & regulations (Solihin & Eastman, 2015). Producing, updating and quality assuring such processes is inconsistent and unreliable (Preidel & Borrmann, 2016). A barrier to interpretation of building regulations is that software is designed by developers that are separate to local authorities (Solihin & Eastman, 2015). The current literature suggests Singapore, Norway, USA & Australia have all implemented BIM automation systems for building regulations. This study reviews current automation systems and based on this proposes a system of creating a checking system is efficient in the control …

Standard Commercially Available Rheometers Are Typically Used to Perform Those Measurements. However, the Results of the Measurement Depend on the Geometry, Testing Procedure and a Number of Potential Artefacts. This Technical Letter Describes the Most Common Techniques and Procedures Used to Assess the Rheological Properties of Cement Paste, as Well as Challenges during Measurements and Actions to Counter These …

Impact Of Surface Ozone Interactions On Indoor Air Chemistry: A Modeling Study, M. Kruza, A. C. Lewis, G. C. Morrison, N. Carslaw

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

An INdoor air Detailed Chemical Model was developed to investigate the impact of ozone reactions with indoor surfaces (including occupants), on indoor air chemistry in simulated apartments subject to ambient air pollution. The results are consistent with experimental studies showing that approximately 80% of ozone indoors is lost through deposition to surfaces. The human body removes ozone most effectively from indoor air per square meter of surface, but the most significant surfaces for C6-C10 aldehyde formation are soft furniture and painted walls owing to their large internal surfaces. Mixing ratios of between 8 and 11 ppb of C6-C10 aldehydes are …

Perception Of Spatial Impression Due To Varying Positions Of The Source On Stage, Sungbeen Cho

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

The listener’s surrounding environment affects the perception of sound. The environment includes physical factors such as space size, shape, and finish materials, and psychological factors such as individual difference of impression, and vision. Acoustic spatial impression can be defined as the concept of the type and size of space at which a listener arrives spontaneously when he/she is exposed to an appropriate sound field. This thesis analyzes how physical factors in enclosed spaces affect the acoustic spatial impression, and how sound sources at different positions on stage are perceived in different shapes of spaces.

First, existing spatial impression parameters, IACC …

Hyperelastic Structural Fuses For Improved Earthquake Resilience Of Steel Concentrically-Braced Buildings, Francys López-Mosquera

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Improving structural resilience (i.e., reducing service interruptions and improving rapidity of function restoration) following extreme events is one of the primary contemporary challenges in structural engineering. While massive casualties have successfully been avoided through the adoption of modern building codes, the sole codified performance objective has been limited to the life safety/collapse prevention range of response. Christchurch, NZ, highlighted the insufficiency of this approach, with large sections of the city nonfunctional after a major earthquake, and with subsequent collapses induced by significant aftershocks. Engineering advances to improve building and community resilience are necessary to mitigate hazards from becoming disasters. This …

The Prevalence Of Six Sigma Trends In The Construction Industry In Pakistan, Muhammad M. Hassan

Masters Theses & Specialist Projects

Economic development in any country or area depends heavily on the performance of the construction industry. This is because the subsequent development of infrastructure increases economic activity, living standards, direct foreign investments, and business opportunities. The construction industry in Pakistan also plays a significant role in its economic activity, and the government’s focus towards increasing infrastructure development provides the construction industry with growth prospects. It is observed that quality management practices in the Pakistan construction industry are highly inadequate to enhance quality. The construction industry there is highly challenged with inadequate delays in projects and project quality. The need for …

Developing A Robust Teaching Portfolio As A Doctoral Student In A Research-Intensive Engineering Program, Anahid A. Behrouzi

Architectural Engineering

Successful faculty applications to teaching/undergraduate institutions can be difficult for doctoral students transitioning directly from a research-intensive engineering program. Oftentimes, these prospective faculty members have limited opportunities to engage in engineering education research, to serve as a primary instructor for a lecture course, or to receive adequate mentoring to prepare them for the environment of a teaching/undergraduate institution.

This paper will highlight the lessons learned by a new faculty member at a top-ranked undergraduate institution (and recent doctoral candidate at a R1 research institution) about how students can build a comprehensive teaching portfolio outside of the traditional coursework and research …

Implementing Subspace Identification On Shake Table Model, Zoe T. Cooperband

Architectural Engineering

Stochastic Subspace Identification is a field of applied mathematics that takes collected experimental time-history data and gives out information about the system that produced the data. SSI is typically used in control analysis but here we apply the methods to the modal analysis of structures. This senior project didn’t involve theory - instead much of the work was in research behind how Subspace Identification works, implementing the algorithm in MATLAB, and applying the program to shake table data to validate the program. In other words, building the framework to make SSI a usable tool and practical learning experience for other …

Mano De La Amistad: A Thin Shell Concrete Structure Designed For The People Of Havana, Cuba, Peter Aster, Marta Blachowicz-Scott, Aaron Cook, Alex Erler, Elizabeth Townsend, Ger Yang

Architectural Engineering

In designing a thin shell structure to cover the performance space on Tribuna Anti Imperialista Jose Marti, in Havana, Cuba, we developed a heavily symbolic concept and further abstracted it to reach our design. Basing the concept on the quote to the right by Obama about US and Cuba relations, we wanted our design to be representative of a hand that works to adjoin the plaza to the US Embassy which is directly west of the site. The “wrist” portion adds an asymmetric element, while the fingers provide a backdrop to the performers as well as a view through to …

The Ginkgo Shell, Mark Luzi, Karla Santos, Josh Cannon, Erika Davis, Nora Villanueva

Architectural Engineering

The overall concept for this outdoor concrete shell structure, located in Furstliche Park in Inzigkofen, Germany, is derived from an abstracted ginkgo leaf. Drawing on inspiration from a poem about the two parts of the ginkgo leaf becoming one, we took the approach of combining both the natural and built environment into one cohesive piece. To connect the two, it was imperative that we place the shell on the site as to have the smallest impact. With a small portion of the overall site used, the unoccupied space further enhances the natural environment. Creating a literal design connection between the …

Shrinkage Cracking In Concrete Tilt-Up Construction, Stewart Hooks, Jack Robinson

Architectural Engineering

The purpose of this project is to investigate a particular, undesirable cracking pattern in concrete tilt-up panels that, until now, did not have a known definite cause. The cause of this cracking pattern is hypothesized to be due to shrinkage restraint of the concrete panels. The cracking under investigation occurs at the bottom corners of the Tilt-Up panels, suggesting that the base of the panel is restrained from shrinkage. This project models various components of Tilt-Up Construction that have potential for restraining the panels from shrinking. This project consists of the following main components.

The first aspect of this project …

Speculations On A City For Mars, Edouard Terzis

School of Architecture - Theses

This thesis proposes the reinterpretation of architectural forms as the index of the constitution of the idea of the city. “Speculations on a City on Mars” is paradoxical in a sense as it superposes both the managerial representation of a city, that is Zoning, along with the speculative aspect of an extra-terrestrial city.

Dermal Uptake Of Phthalates From Clothing: Comparison Of Model To Human Participant Results, Glenn Morrison, C. J. Weschler, G. Bekö

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In this research, we extend a model of transdermal uptake of phthalates to include a layer of clothing. When compared with experimental results, this model better estimates dermal uptake of diethyl phthalate and di-n-butyl phthalate (DnBP) than a previous model. The model predictions are consistent with the observation that previously exposed clothing can increase dermal uptake over that observed in bare-skin participants for the same exposure air concentrations. The model predicts that dermal uptake from clothing of DnBP is a substantial fraction of total uptake from all sources of exposure. For compounds that have high dermal permeability coefficients, dermal uptake …
