the transfer of diaphragm shear forces to the vertical elements. This topic is addressed in detail in Section 4.6. An important element related to diaphragm force transfer is the collector, or drag strut. In Figure 4-31, a member is added to collect the diaphragm shear and drag it into the short intermediate shear wall. The presence of a
AUSTRALIAN DESIGN MANUAL FOR DIAPHRAGM clarification were the effectiveness of the ties acting as shear connectors, and the effectiveness of this type of section (and similar). to resist waterpenetration. 4.1 Shear Connector Tests The shear tests were aimed at checking the British relationships for design of connectors across a mortar joint between a diaphragm and a flange.
All IDOT Design Guides have been updated to reflect the Design Guides 3.3.9 - LRFD Shear Connector Design Page 3.3.9-6 May 2019 Radial shear is then considered when designing stud shear connectors, using the following equation:Ffat = Ffat2 = w Frc (Eq. 6.10.10.1.2-5) Where:Frc = net range of cross-frame or diaphragm force at the top flange

Design/Construction Guide:Diaphragms and Shear WallsA diaphragm acts in a manner analogous to a deep beam or girder, where the panels act as a web, resisting shear, while the diaphragm edge members perform the function of flanges, resisting bending stresses. These edge mem-bers are commonly called chords in diaphragm design, and may be joists, ledgers, trusses, bond beams, studs, top

JUNE 2008 LRFD BRIDGE DESIGN 6-1Provide adequate spacing (2'-0" minimum) between field splices and diaphragm connection plates and stiffeners. Identify Area A on the beam or girder plan sheets. Area A is the portion of the top flange that is in tension due to total dead load. Identifying the tension flange is
SEISMIC BEHAVIOR OF THROUGH-DIAPHRAGM 2.2 Proposed Connections with through Diaphragm To avoid the abrupt change of cross section between the beam flanges and through diaphragm and reduce the stress concentration there, three improved through-diaphragm connection details were studied herein. Specimen JD-2 had a tapered diaphragm with an extended length of 320mm, as
Shear connectors on the top flanges of the steel girders provide the means to achieve composite action between the slab and the girders, thus increasing both stiffness and strength. This article reviews the behaviour of the connectors and the design rules for the shear connection in BS EN 1994-2 [1] .
Steel Deck Diaphragm - Canam BâtimentsThe fluted deck is equivalent to the web of a horizontal beam of which the flanges are the perimeter structural members provides examples on how to calculate the shear in the diaphragm, and indicates how to use the load tables. Shear Connector Connectors at Side-Lap Connectors at Support Perimeter Member Support Member Deck Sheets.
Stiffness and strength of shear diaphragms used for The stiffness requirement for the shear diaphragm given in Eq. (4) is based on an analysis of beams with an initial twist, 0 = L b/(500d), where d = section depth and L b is the spacing between cross-frames. Helwig and Yura also investigated strength requirements for shear diaphragm bracing of stocky beams and proposed the following equation
A metal flange connection for concrete flanges comprising end members exposed at facing ends of a pair of adjacent, generally horizontal concrete flanges and a connecting member between the end members. Each of the end members has a surface along the end of the concrete flange and the connecting member has a first portion extending between the end members in a first generally
Wide-Flange Beam to HSS Column Moment Connections The main difference between an HSS and wide-flange column is how the forces from the beam flanges are transferred into the column webs to be resisted as shear. In a wide-flange column, the web (and thus the stiffness) is located at the center of the column flange.Seismic Corner:Diaphragm-Collector Shear Transfer CISC For larger shear forces, particularly when the design includes the contribution of the concrete cover slab for diaphragm shear resistance, welded-stud shear connectors are commonly used to transfer the diaphragm shear between the deck-slab diaphragm and the main collectors.
