A SIMPLE METHOD OF ENHANCING THE ROBUSTNESS OF R/C FRAME STRUCTURES

June 1, 2016
Author(s)
Yihai Bao, Hai S. Lew, Fahim Sadek, Joseph A. Main
A simple debonding technique is proposed to reduce or eliminate strain localization in reinforcing bars in the region of wide flexural cracks in RC beams to enhance the resistance of RC buildings to disproportionate collapse (also referred to as

Acceleration and Parallelization of ZENO/Walk-on-Spheres

June 1, 2016
Author(s)
Derek Juba, Walid Keyrouz, Michael V. Mascagni, Mary C. Brady, Michael Mascagni
This paper describes our on-going work to accelerate ZENO, a software tool based on Monte Carlo methods (MCMs), used for computing material properties at the nanoscale. ZENO employs three main algorithms: (1)Walk on Spheres (WoS), (2)interior sampling, and

An Improved Method Of Modeling Infiltration In Commercial Building Energy Models

June 1, 2016
Author(s)
Lisa C. Ng, Steven J. Emmerich, Andrew K. Persily
Different strategies for improving building envelope thermal performance are being implemented in commercial building design and construction as well as being incorporated into ASHRAE standards and other design requirements. The energy impacts of

Capacitive Displacement Sensor for Detecting Planar Submicrometer Motion

June 1, 2016
Author(s)
Svetlana Avramov-Zamurovic1, Jae M. Yoo, Nicholas Dagalakis
This paper describes the design of a very simple displacement sensor that measures the displacement of an object by measuring the change in capacitance due to the movement of this object in the sensor fringing electric field. Two sensor geometries with

Energetic Electrons Driven in the Polarization Direction of an Intense Laser Beam Incident Normal to a Solid Target

June 1, 2016
Author(s)
Lawrence T. Hudson, John F. Seely, Nino R. Pereira, H. Chen, G.J. Williams, R.P. Drake, C.C. Kuranz, C.A. Di Stefano, J. Park
Experiments were performed at the LLNL Titan laser to measure the propagation direction of the energetic electrons that were generated during the interaction of the polarized laser beam with solid targets in the case of normal incidence. The energetic

In Situ Structural Characterization of Ageing Kinetics in Aluminum Alloy 2024 across Angstrom-to-Micrometer Length Scales

June 1, 2016
Author(s)
Fan Zhang, Lyle E. Levine, Andrew J. Allen, Carelyn E. Campbell, Adam Abel Creuziger, Nataliya Kazantseva, Jan Ilavsky
The precipitate structure and precipitation kinetics in an Al-Cu-Mg alloy (AA2024) aged at 190 °C, 208 °C, and 226 °C have been studied using ex situ TEM and in situ synchrotron-based, combined ultra-small angle X-ray scattering, small angle X-ray
