Rigid diaphragm analysis example. rigid diaphragm methods.

Rigid diaphragm analysis example. With the formulas provided it is a straight forward matter to automate a rigid diaphragm analysis in a computer program for any number of shear walls. Consider all weak axis member stiffnesses to be negligible: When enabled, the bending member is modeled with infinite flexibility in the weak direction. However, this case has not been considered he Today we have a perfect structural engineering design example of a rigid diaphragm where we figure out how to distribute lateral forces to shear walls. The flexible diaphragm method both underestimates and overestimates the shear wall loads as compared to the rigid diaphragm method. ons. The goal of this presentation is to provide guidance on how to analyze a double open-front, or corridor only shear wall diaphragm, and help engineers better understand flexibility issues associated with these types of structures. It is possible to create a formulation that accounts for walls at an angle to the x axis [3]. Rigid diaphragm multi-point constraints are defined with the rigidDiaphragm method to enforce the rigid in-plane stiffness assumption for the floors. . rigid diaphragm methods. Inelastic cross sections are constructed as developed in this example to account for material nonlinearities. In either non-flexible case (rigid or semi-rigid dia-phragms) a structural analysis is required to determine the horizontal distribution of forces. The building model used for the analysis of the vertical elements of the SLRS can be employed to determine this horizontal distribution. For more information on these flexibility equations, see Torsional Analysis of Rigid Diaphragm Theory - Displacement Behavior of Wall Elements.
