Structural
Testing of Walls and Floorsperformed at the Gene D. Knudson Wood Engineering Laboratory
Department of Wood Science and Engineering College of Forestry
Oregon State University located in Corvallis, Oregon 97331-5751
under the direction of Rakesh Gupta, Ph.D. Associate Professor,
Wood Engineering/Mechanics and Milo Clauson Faculty Research
Assistant.
Civil and
Structural Engineer Jok Ang, P.E. overseeing testing at OSU
states that based on his structural observations during load
tests and evaluation of test results, the ICS structural
components have met the IBC/UBC and ASTM testing criteria.

ICS shown to exceed commercial load applications.
Above graph demonstrates ICS Shear
Wall Test results compared to Conventional (Stick Frame)
Construction Shear Wall Test.
Shear Wall Test
ICS shear walls were tested (above) under monotonic loads following ASTM standard
E564 (ASTM 2001b) and under CUREE cyclic load
protocol (Krawinkler
2000).
Vertical Load Test of Floors
The vertical load test of ICS floors was conducted as shown above.
Each floor was supported at two ends and was loaded using a set of
air bags. The air bags were sandwiched between the ICS test
floor and a reaction floor (and reaction beam) as shown.
Floor Diaphragm Test
ICS floors were tested as diaphragm (simply supported deep beams) to
determine the ultimate shear strength of diaphragms. The tests
were conducted according to the ASTM standard E455 (ASTM 2002a).
Diaphragms were tested as shown above.
