The seismic behavior of a building component (e.g., shear wall) is a fundamental attribute engineers need to assess the earthquake performance of a building. It is no surprise that component behavior is often dependent on the loading history. Repeatedly

ASHRAE Guideline 36 High Performance Sequences of Operation for HVAC Systems was developed to provide a reference set of high-performance control sequences for air-side heating, ventilating and air-conditioning (HVAC) equipment, including multiple-zone
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

ASCE 41 contains methodologies used by practicing engineers for the assessment of existing buildings and the design of new buildings. The National Institute of Standards and Technology recently completed a study investigating the relationship between ASCE
