Complex Wall Project: Planar Wall Specimen Time Lapse Videos
12 Oct 2011 | Multimedia | Contributor(s): Anna C Birely
The image at the top of the movies shows the first floor (lower one-third, or 4 feet) of the test specimen. The bottom center figure shows the drift at the top of the specimen vs. the base moment....
Large Scale Testing of Reinforced Concrete Squat Walls
12 Jul 2011 | Poster | Contributor(s): Josh Rocks
To better design reinforced concrete squat walls for the effect of earthquake shaking, a better understanding of their behavior is needed. This can be done through testing of large scale...
PW2 Damage Progression
Coming soon: Detailed description of the damage progression.
Simultaneous Shear and Axial Failures of Reinforced Concrete Columns
11 May 2011 | Publications | Contributor(s): Santiago Pujol
Axial failure of columns can lead to collapse of a building. Reinforced concrete columns in buildings constructed before modern seismic design codes were enforced may contain inadequate transverse...
PW1 Damage Progression
Below is a detailed discussion of the damage observed during the test of PW1. Included are a set of images selected by the researchers to be representative of the damage progession. Step numbers...
Simulation of the Seismic Response of Low Aspect Ratio Concrete Walls
04 Jan 2011 | Poster | Contributor(s): Josh Rocks
Recent studies have shown that predictive equations used in North America for the peak shear strength of low aspect ratio walls are biased and that the scatter in the ratios of measured to...
Hybrid Simulation of the Seismic Response of Squat Reinforced Concrete Shear Walls
04 Jan 2011 | Poster | Contributor(s): Catherine Whyte
This project will investigate the earthquake response of large-scale reinforced concrete walls through hybrid simulation tests conducted at the nees@Berkeley laboratory site. Squat...

05 Dec 2010 | Databases | Contributor(s): National Institute of Standards (NIST), Taylor and Stone
This performance database contains material and geometric properties, experimental results and reference information from cyclic, lateral-load tests of reinforced concrete columns with spiral...
Dynamic Field Tests of Small-scale Bridge Bents Supported on Drilled Shafts
02 Dec 2010 | Publications | Contributor(s): Puneet Agarwal, Sharon Wood, Asli Kurtulus, Farn-Yuh Menq, Ellen M. Rathje, Kenneth Stokoe
Two, 1/4-scale, two-column, bridge bents were constructed at a field site in Austin, TX. Three different types of dynamic tests were conducted. Initially, the specimens were struck with...
Behavior of Ten-Story Reinforced Concrete Walls Subjected to Earthquake Motions by Jose Dario Aristizabal-Ochoa
27 Sep 2010 | Publications | Contributor(s): Mete Sozen
The overall objective of this work was to investigate the response of multi-story reinforced concrete structures resisting earthquake forces primarily through "cantilever" rather than frame...
Cyclic Response of Concrete Columns Reinforced with High-Strength Steel
16 Sep 2010 | Publications | Contributor(s): Jeffrey Rautenberg
In this paper the use high-strength bars (having a yield stress exceeding 80 ksi) as longitudinal reinforcement for columns is reconsidered. The focus of the work presented is on columns meeting...
