Abstract

A research study was conducted at South Dakota State University to evaluate the performance of cold formed steel walls subjected to loads from bar joists. To fulfill the objective of this research, 32 test specimens were constructed, instrumented, and tested to evaluate the effect of the load distribution members and joist seats on the following: elastic stiffness of the test setup, rotational stiffness of each test, distribution of load to the stud cross section, and distribution of load down the length of the wall. All test setups were loaded using monotonic testing until failure. During testing, strain data was gathered to evaluate the behavior of each test as well as the test setup. This research included a literature review, fabrication and instrumentation of test specimens, load testing each test setup until failure, and an evaluation of the measured data to evaluate the behavior of the test specimens. Testing showed that the joist seat and LDM had an effect on the overall behavior of the tests. The overall effect varied from test to test.
