Updates on Research Task Progresses

Task 4b Plan

This task involves design, construction, and testing of a 2-story full scale mass timber building with the resilient rocking wall system. The new knowledge that will be generated from this test include:

The specimen is shown below, with an open floor plan and reasonably realistic diaphragm aspect ratio

Construction started in June. Testing will start early July.

Test Outcome

A good INTERVIEW on the investigative 2-story building test in 2017 at NHERI@UCSD

Major findings on the test results have been presented in Mass Timber Conference, Structures Congress 2018, NCEE conference in Los Angeles, and World Conference on Timber Engineering in Souel South Korea.

Several publications have been made available in research journals. Check the list of papers in Research page.

The testing videos from the test 14 can be found in this Video List for interested viewers.
