Fundamentals of Column Bases and Exposed Seismic Base Design (Cont. of Large Scale Tests & Micromechanics-Based Simulation of Ultra-Low Cycle Fatigue & Fracture in Steel Structures): Phase 3

PIs: Amit M. Kanvinde (UC Davis) & Gregory G. Deierlein (Stanford University)
Graduate Student: Ivan R. Gomez (UC Davis).

Test schedule: January 3, 11, 22, 31, & February 11, 2008

The aim of the project was to investigate Ultra-Low Cycle Fatigue (ULCF) in large-scale welded steel columns. The extensive experimental study was complemented by detailed continuum-based FEM and micromechanics-based models that capture the fundamental processes of void growth, collapse, and damage responsible for ULCF.

January–February, 2008
Determining the Live Load Capacity of Bridges Designed to Caltrans Seismic Design Criteria Following a Major Seismic (Design) Event

PI: Bozidar Stojadinovic (UCB)
Graduate Students: Vesna Terzic (UCB) and Nicola Tondini (U. of Trento, Italy).

Testing will be performed to evaluate the remaining traffic load capacity of a bridge after an earthquake events. In the November 16 test, a column which had been damaged by applying axial load. The amount of axial load capacity remaing after a controlled amount of leteral load induced demage was measured. These tests will be used to develop the evaluation procudure and modeling guidelines.

Special Demonstration: First-Ever Real-Time Geographically-Distributed Hybrid Simulation Using the Internet

PIs: Steve A. Mahin and Gregory Fenves
Graduate Student: Andreas Schellenberg (UCB)

Mr. Jon Lea, with some help from Andreas Schellenberg, successfully conducted the first-ever real-time hybrid simulation over the Internet. The structure was modeled using OpenSees on a portable computer located at the NEES Inc. headquarters in Davis, CA. It had a physical component located at the micro-nees lab of the nees@berkeley Equipment Site. The connection between the computer and the physical models was established through a general-purpose Ethernet connection and managed using the OpenFresco framework. A 32-second long earthquake record was applied to the hybrid model in a simulation that lasted exactly 32 seconds!

Here is a pdf file with some results of the first ever geographically distributed real-time hybrid simulation. [PDF]
