Structural Performance of Nuclear Power Plant Concrete Structures Affected by Alkali-Silica Reaction (ASR). Task 3: Assessing Cyclic Performance of ASR-Affected Concrete Shear Walls

September 27, 2021
Author(s)
Jonathan Weigand, Fahim H. Sadek, Travis Thonstad, Sorin Marcu, Rudy Villegas, Long Phan, Adam L. Pintar
This report describes the results of Task 3 of a five-task comprehensive research program conducted at the National Institute of Standards and Technology (NIST) under the sponsorship of the U.S. Nuclear Regulatory Commission (NRC). The overall study aims

New Connections for Enhancing Robustness of Precast Concrete Frame Structures

May 18, 2021
Author(s)
Travis Thonstad, Jonathan Weigand, Joseph Main, Hai Lew
The National Institute of Standards and Technology is continuing its research on the mitigation of disproportionate collapse in structural systems typical of U.S. building construction. As part of this research, two ten-story precast concrete moment frame

Simulations of Flow Over an Axisymmetric Hill

February 26, 2021
Author(s)
Rikhi Bose, DongHun Yeo
In this report, high-Reynolds number turbulent flow around an axisymmetric hill is studied using large eddy and unsteady Reynolds averaged Navier-Stokes simulations and the results are extensively validated against experiment. The boundary-layer thickness

Application of ASCE 41 to a two-story CFS building

October 22, 2020
Author(s)
Matthew Speicher, Zhidong Zhang, Benjamin W. Schafer
The objective of this paper is to summarize the evaluation results from applying the updated performance-based seismic design provisions: ASCE 41-17, on a cold-formed steel framed building sited in a location with high seismic demands. The assessment

Seismic Evaluation of a 2-Story Cold-Formed Steel Framed Building using ASCE 41-17

September 29, 2020
Author(s)
Matthew S. Speicher, Ivana Olivares, Benjamin W. Schafer
The objective of this report is to assess the adequacy of new provisions in ASCE 41 for seismic assessment of cold-formed steel framed buildings. A two-story cold-formed steel (CFS) framed building that has been designed to contemporary seismic standards
