This enters the standard castellation pattern corresponding to the given castellated beam. The four point loads should be entered starting with P1 and ending with P4.
In order to verify the adequacy of the pre-composite beam, the percent present before the concrete has hardened should be entered as well. Program allows (1) uniform live load, (1) uniform dead load, and up to (4) point loads. Enter concrete properties (strength, weight, & thickness), deck properties (height & width), and stud properties (diameter, number/rib, & length), and percent composite. If beams longer than 110' are needed please call CMC Steel Products for availability. Enter the beam configuration: span (110'-0" max), spacing (left & right), material strength (36 or 50), and connection type. Enter job name and design mark (not required). CMC Steel Products will provide the most efficient shape (symetric or assymetric) to support specified loadings. CB stands for Castellated Beam, nominally 27 inches deep, (Total Load/Live Load/Precomposite Dead Load). An example of a perfomance specification is: CB27(1100/560/500). Performance Specification: A performance specification is the best way to insure the beam is designed as efficiently as possible. In order to accommodate production processes, CMC Steel Products may from time to time provide an equivolent symetrical size.Ģ. Several common assymetric sections can be selected in the design program. The beam is manufactured from a 35 pound per foot beam on top and a 46 pound per foot on bottom. As before, CB stands for Castellated Beam, nominally 27 inches deep. An example of this specification is CB27x35/46. In composite construction, significant weight savings can be achieved by using a heavier tee section on the bottom and a lighter section on the top.
For example, CB27x40, CB stands for Castellated Beam, nominally 27 inches deep weighing 40 pounds per foot. Direct Specification: When using direct specification the beam is specified in the same manner as a wide flange beam.
#Castellated beam design software how to#
HOW TO SPECIFY: Castellated beams can be specified in one of the following methods:ġ. This condition requires horizontal bridging to be in place before deck bundles are placed. bundle of deck to be placed over three beams no further than 1'-0" from the end of the beam. This condition requires bolted X-bridging to be installed before the hoisting cables are removed. OSHA requires construction bridging to be installed to meet the following loading conditions: 1.

All areas shaded yellow or with a drop box require input information. This program will assist in sizing simply supported, composite castellated beams with point and uniformly distributed loads.
