RE: UCI-CoLA Research

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Have you done the testing for a shear wall panel with opening in the wall?
I would like to know about the result on the following:
1. What is the shear capacity for a wall with opening? How big is the
opening that is allowed in the wall?
2. Impact on the height/width ratio based on the entire wall or on each
individual pier around the opening?
3. Stress distribution at opening and piers.
4. Displacement criteria and test result.
5. Blocking in between studs of wall panel should be continuous through out
the entire width of wall or not?
6. what is the path of shear transfer through piers, the connection at top
and bottom of piers?

This message is being sent to act as a recruitment devise for
from the design profession on timber shear walls.  Since late '98 UC
has been conducting a Light-framed Shearwall Research Project in
with the City of LA.  This project has revolved around the construction,

pseudo-static testing and analyzing of 27 different wall configurations
variable sheathing type and thickness', nail type and spacing as well as

wood and steel stud framing.  To date the project has provided raw and
summarized data related to envelope load-displacement curves, estimates
the yield limit and strength limit states, drift information, etc.
Currently, myself and 2 other graduate students involved in running this

research project, will ultimately use this collected data for the basis
our MS thesis.  As we begin the brainstorming for specific thesis topics
are interested in the ideas and advise of the design professional's.
there any topics that specifically interest you or any ongoing issues in
design community that a thesis paper could address?  If you would like
information on the project e-mail me at asmith(--nospam--at), otherwise we

look forward to hearing your responses/suggestions.

Thank You
