Development and Interpretation of the Security Rating Index

October 12, 2021
Author(s)
Jonathan Sylvie, Stephen R. Thomas, Sang-Hoon Lee, Robert E. Chapman
This article is a follow-on publication to Addressing Security in the Early Stages of the Project Life Cycle. It details the development and interpretation of the Security Rating Index (SRI), which provides a means of quantitatively assessing the level of

Effects of Aspect Ratio of Multi-Walled Carbon Nanotube on Flammability Properties of Polymer Nanocomposites

October 12, 2021
Author(s)
Bani Cipiriano, Takashi Kashiwagi, Srinivasa R. Raghavan, Ying Yang, E A. Grulke, Kazuya Yamammoto, John R. Shields, Jack F. Douglas
The effects of the aspect ratio of multi-walled carbon nanotube (MWNT) on viscoelastic properties and flammability properties of PS/MWNT nanocomposites are studied with two different MWNTs having average aspect ratios of 49 and 150. While no significant

Energy-Based Design Approach for Seismic Design: Energy Spectra

October 12, 2021
Author(s)
P Khashaee, B Mohraz, Fahim H. Sadek, Hai S. Lew, John L. Gross
Among the approaches that the Structural Engineers Association of California has recommended for performance based seismic design is the energy approach. In this approach, the earthquake input energy transmitted to the structure is estimated from ground

Feasibiliy and Fidelity of Data Exchange Through IFC for Building Commissioning

October 12, 2021
Author(s)
Hongjun Wang, Burcu Akinci, J H. Garrett, K A. Reed
The building commissioning (BC) process ensures that the various interacting systems in a building are properly installed and operating. It is a process requiring extensive data exchange among different participants across multiple project phases. The

Hydrolysis-Controlled Transport of Water in Polymeric Coatings

October 12, 2021
Author(s)
Sanghun Lee, Tinh Nguyen, Jonathan W. Martin, E Byrd
Thermoset acrylic melamine coatings are widely used for exterior structures. These materials are formulated by reacting an acrylic polyol with an alkylated melamine. Because the reactions are reversible, acrylic-melamine coatings tend to hydrolyze during

Imidazolium Modified Clay Based ABS Nanocomposites: A Comparison Between Melt-Blending and Solution Sonication Processes

October 12, 2021
Author(s)
M Modesti, S Besco, A Lorenzetti, Mauro Zammarano, V Causin, C Marega, Jeffrey W. Gilman, D M. Fox, Paul C. Trulove, Hugh C. De Long, P H. Maupin
Acrylonitrile-butadiene-styrene (ABS) nanocomposites containing imidazolium-modified montmorillonite have been prepared by melt-blending and solution-sonication in order to study the effects of processing on the morphology and properties of the polymer
