WebMar 26, 2024 · This chapter discusses Section 12.10 of ASCE 7-16, which covers the computation of in-plane floor diaphragm forces, including collector and chord elements. It considers a 6-story office building located near Memphis, Tennessee. Diaphragm forces caused by both inertial and system effects are included. WebChords are critical to carry the tension forces developed by the flexural bending moments in the diaphragm under lateral load. Traditionally, diaphragm chords are thought of as Tension/Compression force couples at the diaphragm extreme edges. The following model and equations illustrate a traditional chord approach for a flexible diaphragm.
