WEBINAR – Full-Scale Shear Wall Tests for Force Transfer Around Openings
November 13, 2013 – 12:00 pm - 1:00 pm
Join at 10 am Pacific, 11 am Mountain, 12 pm Central, 1 pm Eastern
A joint research project of APA – The Engineered Wood Association, University of British Columbia (UBC), and USDA Forest Products Laboratory was initiated in 2009 to examine the variations of walls with code-allowable openings. This study examines the internal forces generated during these tests and evaluates the effects of size of openings, size of full-height piers, and different construction techniques by using the segmented method, the perforated shear wall method and the force transfer around openings method. Full-scale wall tests as well as analytical modeling were performed. The research results obtained from this study will be used to support design methodologies in estimating the forces around the openings. This presentation shares test results from the (8 feet x 12 feet) full-scale wall configurations, which will be used in conjunction with the analytical results from a computer model developed by UBC to develop rational design methodologies for adoption in the U.S. design codes and standards.
Dr. Thomas Skaggs, PE, APA
Tom is the Manager of Product Evaluation in APA’s Technical Services Division. During his 16 years at APA he has been actively involved in dynamic testing of engineered wood products – including vibration performance of I-joist floor systems and evaluating the cyclic performance of braced wall and shear wall assemblies. He was also actively involved in the design and implementation of APA’s full-size three-dimensional house testing program and the recent addition of adding combined shear and uplift testing as well as full-scale diaphragm testing at the APA Research Center. In addition to his extensive test laboratory experience, Tom has served on National Science Foundation funded post disaster investigations. He also participates in the building code development process by serving on both the ASCE 7 Committee and the Wood Subcommittee of Building Seismic Safety Council, which writes the NEHRP Provisions. Prior to joining APA, Tom’s PH.D research at Virginia Tech was in the area of metal plate connected wood trusses. Tom completed his B.S. and M.S. at Texas A&M University. Tom is a licensed Civil Engineer in Washington and has written various articles and a chapter in the award winning APA Engineered Wood Handbook published by McGraw-Hill.
