Concrete Beam support locations DO NOT consider the stiffness of surrounding connected elements.Ĥ. Concrete Beam support locations may ONLY be analyzed as either fully fixed, pinned, or free.ģ. Stiffness is calculated at each analytical location using Bischoff’s method, not a percentage of gross properties.Ģ. Supports are treated as “knife-edge” (zero length).į. Additional net compression in concrete beams due to axial load is disregarded.Į. No P-Delta or P-delta analysis is performed.ĭ. Members are analyzed individually, not as an integral frame.ī. Regardless of how the Revit model is configured, any Concrete Beam sent from Revit to ENERCALC remains subject to the same analysis and design limitations as ENERCALC itself.Ī. Open-ended modification of section geometryīefore using ENERCALC for Revit for the design of Concrete Beams, users should take special note of the following limitations:ġ. Verifying T-Beam effective width where applicableĤ. Specifying the rebar materials of the beam reinforcementģ. Specifying the concrete material properties of the beamĢ. The primary characteristics that distinguish concrete beam calculations from conventional Steel beam, Steel Composite, and Wood calculations are:ġ. Concrete beams share all of the common beam behavior described in the preceding sections.
