Impact of Detailing on the Lateral Performance of Cold-Formed Steel Framed Walls

June 27, 2022
Author(s)
Zhidong Zhang, Matthew Speicher, Amanpreet Singh, Tara Hutchinson, Benjamin Schafer
The main objective of this study is to investigate the impact of structural and non-structural detailing that is not directly accounted for in conventional lateral strength and ductility design of wall-lines constructed of cold-formed steel (CFS) framed

Measurement Methods and Techniques for Pressure Losses in Pipe Fittings

June 25, 2022
Author(s)
Lingnan Lin, Marylia Duarte Batista, Natascha S. Milesi-Ferretti
Pressure losses in pipe fittings are important design information for sizing pipelines and selecting pumps. Currently, there is no standard method of test for determining the pressure loss of pipe fittings. To assist future development of a standard method

Certification of Standard Reference Material(R) 114r Portland Cement Fineness

June 6, 2022
Author(s)
Eduarda Votri, Blaza Toman, Paul E. Stutzman
The SRM 114 series for portland cement fineness has been provided by NIST since 1934 for use in calibrating instruments for measuring fineness characteristics of portland cement and other powdered construction materials. SRM 114r is the latest of this

Assessment of the reason for the vitrification of a wall at a hillfort. The example of Broborg in Sweden

May 9, 2022
Author(s)
Rolf Sjoblom, Eva Hjarthner-Holdar, Carolyn Pearce, Jamie Weaver, Erik Ogenhall, John McCloy, Jose Marcial, Edward Vicenzi, Michael Schweiger, Albert Kruger
It was discovered around 250 years ago that some of the rock material in the walls of some hillforts had been subjected to such high temperature that it had vitrified. This prompted a debate as to the reason for it that is still going on today: did the

Models for an Ultraviolet-C Research and Development Consortium

March 25, 2022
Author(s)
Dianne L. Poster, C Cameron Miller, Yaw S. Obeng, John J. Kasianowicz, Michael T. Postek, Norman Horn, Troy Cowan, Richard Martinello
The development of an international, precompetitive, collaborative, ultraviolet (UV) research consortium is discussed as an opportunity to lay the groundwork for a new UV commercial industry and the supply chain to support this industry. History has

Bioinspired Wear-Resistant and Ultra-Durable Functional Gradient Coatings

January 28, 2022
Author(s)
Zhengzhi Wang, Kun Wang, Houbing Huang, Xiao Cui, Zuoqi Zhang, Martin Chiang
For mechanically protective coatings, the coating material usually requires sufficient stiffness and strength to resist external forces and meanwhile matched mechanical properties with the underneath substrate to maintain the structural integrity. These
