CUREE-Caltech Woodframe Project

Element 1 - Testing & Analysis
Task 1.2 – Organization of an International Benchmark

PI: Chia-Ming Uang (University of California, San Diego)

Problem Statement

The international engineering community has been invited to blind-predict the inelastic seismic response of a two-story woodframe house tested under the CUREE-Caltech Woodframe Project. This exercise will provide a unique opportunity to assess the state-of-the-art of numerical models for woodframe structures and will help foster cooperation between the CUREE-Caltech Woodframe Project and other related research activities.

Main Objectives

The main objective of Task 1.2 is to organize an International Benchmark based on one particular shake table testing phase of Task 1.1.1 of the CUREE-Caltech Woodframe Project.

Methodology

Task 1.2 incorporates the following five main parts, namely:

Part 1 - Announcement of the International Benchmark
A promotional flyer was prepared to announce the International Benchmark and sent out to over 150 potential participants from the engineering and research community worldwide.

Part 2 - Promotion of the International Benchmark at the World Conference on Timber Engineering
The International Benchmark was promoted at a CUREe-Caltech Woodframe Project display booth sponsored by UCSD at the World Conference on Timber Engineering, held at Whistler, British Columbia on July 31 to August 3, 2000.

Part 3 - Preparation of an Information Package to Participants
An information package was sent out to all registered participants of the International Benchmark on September 15, 2000. This package detailed the basic data on the test structure, material properties and ground motions used for the shake table tests. A description of the various analyzes and specific responses requested from the participants were also provided. The types of analyzes requested ranged from qualitative performance evaluation to full nonlinear dynamic analyses.

Part 4 - Preparation of a Comparative Report
After submission of the blind predictions on January 15, 2001 by the participants a report comparing these predictions with the experimental results will be complied. This report will be distributed to the participants.

Part 5 - Preparation of a Workshop
A workshop will be held on June 15th, 2001 at UCSD at the end of the benchmark. One representative of each participating team will be invited to present their modeling assumptions and predictions. The workshop proceeding will be published.

More Information

A team of six different countries have registered as benchmark participants and will be represented at the June 15th, 2001 Workshop.
