Shear wall panel design.

Two weeks ago i had the chance to present to the young members group of the structural engineering association of metro washington on the topic of multi story light frame shear wall design with all of the large firms in the d c. A shear wall is an rcc structural member used in a frame structure to resist the lateral forces develop by winds or seismic forces generated due to the earth quicks. The required minimum length of a shear wall panel generally ranges from 4 to 8 of wall with no openings. Wood structural panel shear walls are permitted to resist horizontal forces using the allowable capacities where panels are fastened to framing members with staples requirements and limitations of af pa sdpws shall be met and the allowable shear values set forth in table 2306 3.

Note that the 2006 ibc section 2305 3 9 allows for wind conditions the shear capacity of the gypsum sheathing to be added to the wood structural panel capacity. 2306 3 1 2306 3 2 or 2306 3 3 shall be permitted. Sheathing type and thickness sheathing nailing size and spacing chord design tension and compression collector design tension and comp. For the design of shear walls with openings the designer has the option of using the segmented perforated or force transfer around openings classifications.

Three shear wall types design considerations. All wall segments must meet the shear wall aspect ratio requirements of ibc table 2305 3 4 which for wind design is 3 5 1. In the high rise buildings we mainly use these walls.
