According to the Experimental Results, the Shear Thickening Effect is Found to Be Strongly Influenced by the Addition of the Chemical Admixture (A Polycarboxylate Ether based Superplasticizer), Whereas Mineral Additions Were Found to Modify the Intensity of Shear Thickening. the Limestone, Quartzite and Fly Ash Addition …

Macarthur Park Master Plan, Community Design Center

Community Design Center Project Reports

Like waterfronts and transit stops, parks leverage value in urban areas. While much recent attention has been given to the signature mega-park, the value of the small-scale neighborhood park in reinventing the city has been overlooked. Once connecting neighborhoods of differing character, and sponsoring more than 80 residential structures along its edges, the historic MacArthur Park at the edge of downtown Little Rock is radically underutilized as an urban neighborhood asset. Severed from its neighborhoods along two edges by interstate construction in the 1960s, this moribund 40-acre municipal park is left with only 16 residential structures along its frontage. The …

Taproot™ Technology: Tree Coring For Fast, Noninvasive Plume Delineations, Joel Gerard Burken, Sallie Bailey, Matt Shurtliff, Jeff Mcdermott

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In Efforts to Evaluate the Use of Plants as a Forensic Tool for Delineating Contaminated Soil and Groundwater, a Laboratory Experiment and a Field Sampling Effort Were Undertaken. Site Assessments Are Often Costly and Inaccurate, Requiring Multiple Mobilizations to Hone in on Source Areas and Getting Accurate Estimates of Contaminant Extent and Distribution. as These Extensive Site Delineations Take Place, Valuable Time and Resources Are Lost. the Findings of This Study Show that Plants Can Be Used as a Tool to Evaluate a Variety of Subsurface Contaminants, Either in the Vadose Zone or in the Saturated Zone. in the First …

Risk Indexes For Draft Ccl3 Chemicals, J. Alan Roberson, Matthew Lueders, Craig Adams, Jeffrey S. Rosen

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

To supplement the processes used for developing the draft third Contaminant Candidate List (CCL3) and better inform decisions made by the US Environmental Protection Agency on future CCLs, the authors offer an evaluation tool for efficiently synthesizing, visualizing, and organizing data for effective comparisons among contaminants. Graphical presentations of health effects-occurrence indexes were developed for more than 300 chemical contaminants, including those on the draft CCL3. a risk indexes framework was then used to elucidate the extent of available data, the data quality, and the underlying uncertainties for occurrence and toxicity. Choosing the appropriate contaminant for regulation is a complex …

Predicting The Perforation Response Of Honeycomb Sandwich Panels Using Ballistic Limit Equations, William P. Schonberg, Frank Schäfer, Robin Putzar

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Man-made debris from previous spacecraft missions poses a serious threat to spacecraft that are launched to operate in Earth orbit because it can strike such spacecraft at extremely high velocities and consequently damage mission-critical systems. Most satellites are constructed with honeycomb sandwich panels as their primary structural elements. to be able to perform a risk analysis, it is important to know, in the event of such a meteoroid or orbital debris particle impact, whether or not the impacting particle or parts thereof will exit the rear of the sandwich panel. a recently developed set of ballistic limit equations for two …

Preparing Students For The Environment Of The Practice Of Consulting Engineer, James Mwangi, Craig Baltimore, Brent Nuttall

Architectural Engineering

In the United States of America, the body of knowledge required for an individual to be allowed to take the engineering licensing examination, which on passing allows the individual to be in responsible charge of engineering projects, is usually defined by laws and regulations of each state. In California, the shortest path taken by most individuals is one where the individual graduates from an ABET accredited undergraduate program; passes the Engineer in Training (EIT) examination and works under the supervision of a licensed engineer for two years (one year if the individual has a Masters degree in relevant field).

Capstone Projects: Integrating Industry Through Student Leadership, Brent Nuttall, James Mwangi, Craig Baltimore

Architectural Engineering

Capstone projects provide a unique opportunity for developing student leadership skills while integrating industry partners. While models for including industry partners in capstone projects have been discussed in prior literature, these models focus on faculty leadership in developing industry partnerships. This paper describes a capstone project model that encourages student, not faculty, leadership in engaging industry partners. Factors that influence successful project teaming of students and industry partners are identified and described using case study examples. The successes and difficulties of integrating industry in capstone project via student leadership are explored.

Teaching The Design: Timber Shear Walls And Developing Student Engineering Judgement And Intuition Through A Hands-On Experience, Craig Baltimore, James Mwangi, Brent Nuttall

Architectural Engineering

Engineering judgement and intuition are vital characteristic of the design profession. Engineering judgement and intuition are developed through experience. This experience is gained by designing a building (working with industry disciplines and the owner); analyzing the building (calculations); being part of the construction process (constructability), and walking through the final product (end user). Teaching design means, in part, developing engineering judgement and intuition. This may best be accomplished by incorporating active learning experiences.

For timber and masonry buildings, the shear wall is the lateral resisting system of choice. A hands-on experience has been developed as a simple exercise in constructing …

Corporate Social Responsibility Of Architectural Design Firms Towards Sustainable Built Environment In South Africa, Ayman Ahmed Ezzat Othman

Architectural Engineering

The construction industry makes a vital contribution to the social and economic development of every country. Buildings provide their users with places for housing, education, culture, medication, business, leisure and entertainment. None of these buildings will perform its function unless supported with efficient road networks, superlative telecommunications facilities, water and electricity. On the other hand, the construction industry has major impacts on the environment. It is a very large consumer of non-renewable resources, a substantial source of waste, pollution, land dereliction and energy consumption. This highlights the responsibility of present generations to use the available resources in a way that …

Incorporating Constructability In The Design Of Masonry Structures, James Mwangi, Craig Baltimore

Architectural Engineering

The International Building Code (IBC) has now been adopted as the model design code for most states and territories of the United States of America. For Masonry design, the IBC references the Building Code Requirements and Specification for Masonry Structures (MSJC) for material properties, design procedures, specifications and quality control. Individual state codes then amend the two documents (IBC and MSJC) appropriately.

In high seismic regions of the United States, hollow block of concrete masonry units (CMU) are the material of choice in masonry construction. The CMU’s are built using sand, pea gravel, cement and water. CMU is typically delivered …

Damage Characterization Of Beam-Column Joints Reinforced With Gfrp Under Reversed Cyclic Loading, Aly M. Said

Civil and Environmental Engineering and Construction Faculty Research

The use of fiber reinforced polymer (FRP) reinforcement in concrete structures has been on the rise due to its advantages over conventional steel reinforcement such as corrosion. Reinforcing steel corrosion has been the primary cause of deterioration of reinforced concrete (RC) structures, resulting in tremendous annual repair costs. One application of FRP reinforcement to be further explored is its use in RC frames. Nonetheless, due to FRP's inherently elastic behavior, FRP-reinforced (FRP-RC) members exhibit low ductility and energy dissipation as well as different damage mechanisms. Furthermore, current design standards for FRP-RC structures do not address seismic design in which the …
