WebThe SDI Diaphragm Interaction Calculator is a web based tool that allows for easy calculation of steel deck diaphragms under the influence of combined wind uplift and diaphragm shear in accordance with the AISI S310 North American Standard for the Design of Profiled Steel Diaphragm Panels. WebA Rigid Diaphragm is a planar collection of nodes that exemplifies infinite in-plane stiffness and moves in the diaphragm plane as a rigid body. This leads to an absence of axial, shear, and moment forces within the diaphragm. An example of a rigid diaphragm in practice could be a reinforced concrete slab, where the bending in-plane is ... Webpremium to a Concrete Special Moment Resisting Frame(SMRF). This cost is mostly since columns in HMF systems need to be larger to accommodate the larger joint shear as well as the reduced column cross section due to the duct. If we could come up with a way to enhance the joint shear of the column by 25% +/- it could help make this system more cost early help referral barnsley
