WebJan 10, 2024 · Thickness and stiffness of diaphragm were measured at the peak inspiration and end expiration phases. Intraclass correlation coefficients test was used to assess the … WebJun 6, 2011 · All shear forces for a steel diaphragm with no sidelaps must be transferred through the joist fasteners, usually puddle welds. Also with no sidelaps, you obviously are going to have more deflection/diaph. movement, because of the lesser stiffness of the entire system like JAE said.
