1.1 Steel Deck Fastener Design and Selection
1.1.9 How to use Diaphragm Shear Tables
General : The following Product Technical Guide Sections 1.2 to 1.6 provide Hilti fastener product technical data sheets and pre-calculated diaphragm shear and stiffness tables using the design equations provided in Section 1.1.8 . Pre-calculated diaphragm shear and stiffness tables are provided in two formats .
Tables in Sections 1.2 , 1.3 and 1.4 are in a traditional design format with diaphragm shear and stiffness values within the table .
Tables in Section 1.6 are in a Hilti alternative format with cost optimized Hilti frame fastener patterns , Hilti sidelap connector ( SLC ) spacings and deck gauge for a given diaphragm shear load demand . This alternative format provides a means for quick reference in order to determine cost optimized equivalent fastening solutions based on diaphragm shear load only .
In all cases , diaphragm shear values determined using either table format are consistent .
These tables do not take into account other design factors , such as gravity or wind uplift loads . These requirements should be checked separately by the Structural Engineer .
Traditional diaphragm shear tables : Sections 1.2 , 1.3 and 1.4 provide tables in a format similar to those published in the SDI DDM03 , CSSBI and most steel deck manufacturers ' catalogs .
As shown in Figure 18 , these diaphragm shear tables are generally created with span across the heading and sidelap spacing along the left margin or column . Along with other design variables such as deck gauge and fastener pattern , the tables are populated with the corresponding diaphragm shear and stiffness values .
The Structural Engineer searches through the various combinations until a diaphragm shear and stiffness factor is found that meet the design requirements .
Optimized diaphragm shear tables : Section 1.6 provides tables in an alternative format that helps a Structural Engineer to quickly select a cost optimized Hilti frame fastener pattern , Hilti sidelap connector ( SLC ) spacing and deck gauge combination to satisfy the diaphragm shear load requirement found in the left column of the table ( Reference Figure 19 ). These tables are based on diaphragm shear capacity only , diaphragm stiffness must be verified separately .
