Shear walls have been used for many years as a lateral-force-resisting element for wood-member, light-framing construction. Ventilation requirements for attic roof spaces have been in place for just as long, but seldom has the topic of integrating the ventilation space with the connection between load carrying diaphragms with load resisting shear walls been addressed in the literature. The one reference found is the APA guide Introduction to Lateral Design, which mentions a technique to install blocking every other framing spece to accommodate venting in the spaces left open. It continues to explain that decreasing the nail spacing by half in the areas that remain, which results in twice as many nails in these spaces, can perform the same amount of shear transfer as a connection which has solid continuous sheathing. However, the guide does not mention any evidence to support the theory. This report describes similar design examples which have reduction values assigned for void spaces, analyzes the internal forces involved in placing vent spaces in different areas of the wall, lists the procedure and data from laboratory testing of shear wall specimens with and without vent spaces of two different capacities, and examines the difference between predicted and laboratory test results. The laboratory tests indicate there is not a reduction in strength due to the placement of void spaces in shear transfer connections, which proves the APA theory correct. A shear wall acts as a system of many parts, and for reasons not fully understood, the internal forces seem to distribute around openings to increase the overall performance of the wall. This report gives recommendations on future tests to validate the increase in strength that was observed.   Copy/Holding information Location Collection Call No. Status   Walter Schroeder Library Master's Theses AC805 .G76 2004 Available Add Copy to MyList Format: HTMLPlain textDelimited Subject:   Email to:
