Verifying The Cause Of Panel Cracking - A Case Study, Jack Robinson, Stewart Hooks, John W. Lawson

Architectural Engineering

Despite the multitude of benefits tilt-up construction has to offer in low rise commercial buildings, there is still room for improvements in the performance of tilt-up buildings. One opportunity for improvement is to minimize a particular, undesirable cracking pattern often seen in concrete tilt-up panels (See Figure 1), which in some cases requires significant cosmetic patching (See Figure 2). This concrete cracking can first appear as non-problematic and non-structural, but even small cracks can become weathered and lead to water intrusion and rebar corrosion. At the very least, these cracks are cosmetic concerns for the owner or tenant potentially resulting …

Valuing Variations In Accordance With The Principle Irish Standard Forms Of Building Contract – Worked Examples And Solutions, Tony Cunningham

Other Resources

Given the nature of the construction process some change is almost inevitable. Standard forms of contract, therefore, cater for such change by including provisions which permit variations and alterations to the works. Variations may range from small inconsequential changes to major revisions which can delay and disrupt the completion to the project and place the project budget under considerable stress.

Establishing a realistic valuation for variations is not always a straightforward task. Even apparently simple changes can have significant unexpected consequences on project outcomes. This study examines how the valuation of variations may be carried out in accordance with the …

Dermal Uptake Of Benzophenone-3 From Clothing, Glenn C. Morrison, Gabriel Bekö, Charles J. Weschler, Tobias Schripp, Tunga Salthammer, Jonathan Hill, Anna Maria Andersson, Jørn Toftum, Geo Clausen, Hanne Frederiksen

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Benzophenone-3 (also known as BP-3 or oxybenzone) is added to sunscreens, plastics, and some coatings to filter UV radiation. The suspected endocrine disruptor BP-3 has been detected in the air and settled dust of homes and is expected to redistribute from its original sources to other indoor compartments, including clothing. Given its physical and chemical properties, we hypothesized that dermal uptake from clothing could contribute to the body burden of this compound. First, cotton shirts were exposed to air at an elevated concentration of BP-3 for 32 days; the final air concentration was 4.4 μg/m3. Next, three participants wore the …

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 …

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 …

Bim+Blockchain: A Solution To The Trust Problem In Collaboration?, Malachy Mathews, Dan Robles, Brian Bowe

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 …
