Thus the module creates a very accurate variable stiffness model of the beam based on actual moments. The effective moment of inertia for each segment (for each load combination) is calculated using the actual unfactored moment on that segment. This module divides each span into a series of segments. NOTE: It is important to know how this module operates with regard to beam stiffness along the span, and how this affects multi-span beams. On the right side of this tab are all the required rebar, concrete strength and elastic modulus entries, shear stirrup data, strength reduction factors and deflection criteria to check. Selecting Single Span Beam on Elastic Foundation will remove the ability to select end support conditions, and it will provide an entry for the Modulus of Subgrade Reaction of the supporting soil. In the screen capture below you can see the two large selection boxes.

This module also has a beam on elastic foundation option for single-span beams. That shape can have up to six groups of reinforcing per span, and the reinforcing can vary on a span-by-span basis. The concrete beam module handles single- and multiple-span beams using ONE cross section shape. When a concrete beam calculation loads in the ENERCALC interface, the user will not find options to toggle the beam section type (unlike conventional non-Revit-linked calculations).In this section, for each input tab we will review only the items that are unique to the CONCRETE material type. Since there is no design counterpart in ENERCALC for a trapezoidal T-Beam or a trapezoidal beam connected to a slab, this configuration will cause the calculation launch to halt with a warning: This beam family is visible in the Revit 'Project Browser' and may be manually applied to any beam instance using the 'Properties' pane:ĮNERCALC for Revit supports the design of trapezoidal concrete beams, but does not permit a concrete beam to be joined to the concrete slab: Because the default out-of-box family content provided by Revit does not include a trapezoidal beam family adequate for ENERCALC for Revit data exchange, ENERCALC for Revit will automatically load a version-appropriate trapezoidal beam family when a new Revit project (.rvt file) is opened.
