3.5.1.8 HOW TO USE DIAPHRAGM SHEAR TABLES
General : The following Product 36 / 7 Technical Guide Sections 3.5.2 to 3.5.5 provide Hilti fastener product technical data sheets and pre-calculated diaphragm shear and stiffness tables using the design equations provided in Section 3.5.1.7 . Pre-calculated diaphragm shear and stiffness tables are provided in two formats .
Tables in Sections 3.5.2 , 3.5.3 , 3.5.4 and 3.5.5 are in a traditional design format with diaphragm shear and stiffness
36 / 9 values within the table . These tables do not take 6 '' into account other design factors ,
36 ''
1-1 / 2 '' such as gravity or wind uplift loads . These requirements
should be checked separately by the Structural Engineer .
Traditional diaphragm 36 / 5 shear tables : Sections 3.5.2 , 3.5.3 , 3.5.4 and 3.5.5 provide tables in a format similar to those published in 6 the '' SDI DDM04 , CSSBI and most steel deck
36 ''
1-1 / 2 '' manufacturers ' catalogs .
As shown in Figure 18 , these diaphragm shear tables are generally created with span across the heading and number of sidelap screws along the left margin or column . Along with other design variables such as deck gauge and fastener
36 / 7 pattern , the tables are populated with the corresponding
diaphragm shear 6 '' and stiffness values . 36 ''
