This study quantifies the impact of different ground motion selection methods on the seismic performance evaluation of steel special moment frames. Two methods are investigated: a "traditional" approach, herein referred to as the PEER method, and a newer
A methodology is presented for calculating the uncertainty associated with the estimation of peak pressure coefficients from wind tunnel test records of various lengths, and how this uncertainty affects design wind effects. Investigation of time series
The standard reference materials (SRM) for fineness of cement are SRM 114 and SRM 46h. They are an integral part of the calibration materials routinely used in the cement industry to qualify cements for ASTM C204 (Blaine), C115 (Wagner) and C430 (45 m
This paper presents the results of a study investigating the correlation between the seismic performance of an ASCE 7 code-compliant steel building with special moment frames and its associated seismic performance as quantified using ASCE 41 analysis
ASCE 41 component backbone curves are typically based on envelopes of data from lab tests of specimens subjected to simulated seismic demands. Prior editions of ASCE 41 required loading protocols having fully-reversed cyclic loading at increasing

The need for improved building performance is global and has led to numerous international collaborations. Since 2000, the International Energy Agency (IEA) Energy in Buildings and Communities Program (EBC, formerly ECBCS) has completed two building
Many existing reinforced concrete moment frame buildings in high seismic regions around the world, including the U.S., were built without adequate seismic detailing requirements. Identifying the level of collapse criticality of these buildings in terms of
A series of experiments was conducted to examine the potential to use kitchen-installed photoelectric smoke detection devices to warn of approaching ignition of food during unattended cooking. An electric range, range hood, and cabinets were installed in a
Structural engineers in the United States have turned to performance-based design methodologies for design of new buildings in order to find improved design solutions as compared to those obtained using prescriptive design provisions of current model

This paper quantifies the impact of using different ground motion selection methods to evaluate the seismic performance of steel special moment frames. Two methods are investigated: a "traditional" approach, herein referred to as the PEER method, and a
This paper presents the results of a collapse prevention seismic performance assessment using ASCE 41-06 for six special concentrically braced frames designed in accordance with the 2012 International Building Code. The correlation between ASCE 7-10 and
ASCE 41-13 is an industry standard for seismic evaluation and retrofit of existing buildings. Alternative component modeling and acceptance criteria are based on a backbone curve constructed from an envelope of component hysteresis loops derived via
Homeowners and builders have increasingly strived to build low energy homes. As building materials, equipment, and methods have improved and renewable energy systems have become commonplace, the goal of net-zero energy homes has become technologically
The Facility Smart Grid Information Model (FSGIM) standard is one part of a larger ecosystem of standards that support the development and implementation of a smart electric grid. The FSGIM uses Unified Modeling Language to define key concepts that must

The time that it takes an occupant population to reach safety when descending a stair during building evacuations is typically estimated by measureable engineering variables such as stair geometry, speed, stair density, and pre-observation delay. In turn

Performance-based methodologies to evaluate the fire performance of structures are needed to move beyond the prescriptive procedures presently in use, which cannot be used to determine actual structural performance in fire. Analytical methods are needed
One of the key concepts of a modernized smart grid is to combine modern communication technology with an improved electric grid to enable energy consumers to exchange information with energy suppliers in order to collaboratively manage electricity supply
