Certification of SRM 2493:Standard Reference Mortar for Rheological Measurements

October 4, 2017

Alex Olivas, Chiara C. Ferraris, Nicos Martys, Edward Garboczi, Blaza Toman, William L. George
Rheological measurements are often performed using a rotational rheometer. In this type of rheometer, the tested fluid is sheared between two surfaces, one of which acts as the rotating surface [1]. Usually, the rotational velocity is imposed and the

Double-shear tests of high-strength structural bolts at elevated temperatures

Rafaela Peixoto, Mina S. Seif, Luiz Vieira
The behavior of high-strength structural steel at elevated temperatures, especially under shear loading, is not well established in the literature. This paper presents results from recently conducted tests on high-strength structural bolts subject to

Behaviour of high-strength bolts at elevated temperatures under double-shear loading

During fire events, connections in steel structures may be subjected to large unanticipated deformations and loads. Those fire effects can produce failures of connections, including local buckling of the connection zone, rupture of connection plates, shear

Modelling and Influencing Human Behaviour in Fire

August 22, 2017
Author(s)
Steve Gwynne, Erica D. Kuligowski, Michael Kinsey, Lynn Hulse
The purpose of this article is to present a conceptual model of human behaviour in fire and its impact on evacuation modelling, life safety analyses, and evacuation procedures. This model is based on a theoretical framework of individual decision-making

Scaling Methods for Dynamic Building System Simulation in an HVACSIM+ Environment

August 9, 2017
Author(s)
Zhelun Chen, Jin Wen, Anthony J. Kearsley, Amanda Pertzborn
A robust and efficient nonlinear algebraic and differential equations solver is increasingly essential as the scale of dynamic building system simulation grows larger and the models employed become more complex. There are many factors affecting the

Performance Monitoring of Chilled Water Distribution Systems using HVAC-Cx

July 30, 2017
Author(s)
Natascha S. Milesi-Ferretti, Michael A. Galler, Steven T. Bushby
Automated commissioning tools facilitate an ongoing commissioning process to improve occupant comfort, ensure the persistence of correct system operation, and reduce energy consumption. These tools decrease the time and the skill level required to carry
