Steel roof and floor deck diaphragm design requires careful attention to load paths stiffness variations fastener types and regional preferences Figure 1 In its most basic form a diaphragm behaves as if it were a short deep beam Shear diaphragms are commonly used in buildings as a means of transmitting lateral loads In building design these loads are typically caused by wind Special Steel Beam Connections This type of connections is used for the case where the arrangements of the structural element are in such a way that standard connections cannot be used For example intersection angels might be different by a certain degree and when beam centers offset from column centers If two layer of steel bars are placed in a beam then the distance between them shall not be less than 25 mm Concrete protection for reinforcement the designer must maintain minimum thickness or concrete cover outside of the outermost steel to provide the steel with adequate concrete protection against fire and corrosion According to ACI Code 7 7 concrete cover of 40 Example 10 Design of a Beam Bearing Plate Example 11 Design of a Column Base Plate Beam Columns Members Example 1 Determining which AISC Specification interaction equation is applicable for a given beam column and checking adequacy Example 2 Analysis of steel beam column braced against sideswayWorked Example – 5 Made by SRSK Date 01 10 00 Structural Steel Design Project Calculation Sheet Checked by VK Date Design Example 5 Design a bolted web cleat beam to column connection between an ISMB 400 beam and an ISHB 200 40 kg m column The connection has to transfer a factored shear of 150 kN Use bolts of diameter 20 mm and grade 4 6
