WebDiaphragm shear at line A and on the north side of line B is 28 200 240 118,. lbs ft = plf Diaphragm shear at the south side of line B and at line E is 101 000 320 316,. lbs ft = plf North-south direction Diaphragm forces for the north-south direction are computed using the same procedure and assumptions as the east-west direction and are shown ... WebFeb 6, 2024 · Diaphragms are typically classified into three categories: rigid, flexible and semi-rigid. a- Rigid diaphragms . ASCE7-10 ( section 12.3.1.2) permits the assumption of rigid if the diaphragms aspect ratio is 3 or less for seismic and 2 or less for wind load ( section 27.5.4 of ASCE7-10) if the structure has no significant horizontal ...

WebMar 2, 2024 · For a building with a rigid frame on each exterior wall, your bending moment and chord forces will be identical regardless of whether you call it a rigid diaphragm or a flexible diaphragm. If you add an intermediate frame, your moment diagrams will change (2 simple spans for flexible, vs 1 continuous span for rigid), but these moments still ... Webcenterlines are zero, and thus rigid constraints can be applied to model a rigid diaphragm (e.g. steel sections, elastic materials) • For nonlinear-beam column elements with RC fiber section where the neutral axis shifts due to bending in the beam axial strains at element’s centerlines are no longer zero.
