    Guide to the Design of Diaphragms, Chords and Collectors by Timothy Mays through NCSEA has been my go to. He always tried to make his books as practical as possible. Also there is a NHERP publication for diaphragms out there but I don't recall the name. hence the need for a decision early in the design process. Collectors, Chords and Connections Diaphragms in steel buildings also typically consist of collector and chord member components, which are nec-essary to transfer the forces to the primary SFRS. These members are loaded axially and are commonly composed of steel floor beams.

Is there a valid way to model and design chords and collectors within RAM? Way back when I used to disconnect column nodes from the diaphragm so the load was placed into the beams. I found it to be a bit cumbersome and ended up doing my collector design outside of RAM.

Many publications on lateral design do not address the design of diaphragms, chords and collectors in much detail.

This Guide fills that void by explaining the role that diaphragms, chords and collectors play in buildings and providing detailed examples of how to determine the seismic forces and design the diaphragm, chords and collectors for various types of buildings located in Seismic Author: International Code Council.

A 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.

ASCE has introduced a new Section Alternative Design Provisions for Diaphragms, Including Chords and Collectors. It is mandatory for precast concrete diaphragms in Seismic Design. A collector element that receives shears from both sides is designated as a “collector.” Discontinuities and irregularities.

Discontinuities in diaphragms are often created when a portion of an exterior wall line is offset from the main wall line, causing a disruption in the diaphragm chord or strut.

The lateral force is transferred through the web of the diaphragm to the walls, which act as supports for the diaphragm. Because the wall on the left does not extend the full depth of the diaphragm, collector elements are needed to collect the shear from the diaphragm and to transfer it.
