# Composite Beam Design with Verco Floor Deck Based on AISC 360-05 / IBC 09

Designing a composite beam with Verco floor deck based on the AISC 360-05 and IBC 09 codes involves several steps. Here is a general outline of the design process:

Determine the Design Loads:

Identify the live load, dead load, and any other applicable loads specified by the project requirements or codes.
Determine the load duration factors, such as short-term or long-term loads, as specified by the codes.
Select the Verco Floor Deck:

Consult the Verco product catalog or contact the manufacturer to select the appropriate floor deck type and gauge based on the project requirements and construction constraints.
Determine the Deck Properties:

Obtain the required properties of the Verco floor deck, such as section properties, moment of inertia, and section modulus. These values can be provided by the manufacturer or calculated based on the deck profile.
Design the Composite Beam:

Determine the effective flange width (beff) of the composite beam based on the Verco floor deck type and profile.
Calculate the moment of inertia (Ieff) and section modulus (Seff) of the composite beam using the appropriate formulas provided in the AISC 360-05 code.
Determine the maximum allowable deflection based on the project requirements and applicable code limits.
Calculate the required section modulus (Sreq) of the composite beam based on the maximum allowable deflection.
Select a suitable steel section that satisfies the required section modulus.
Check Composite Action:

Verify that the composite action between the steel beam and Verco floor deck is achieved. This can be done by comparing the moment capacity of the composite beam (Mn) to the applied factored moments.
Check Shear Capacity:

Calculate the factored shear forces on the composite beam and verify that the shear capacity of the beam is sufficient to resist these loads.
Check Deflection:

Verify that the composite beam’s deflection under the factored loads is within the allowable limits specified by the codes.
Provide Detailing and Connection Requirements:

Determine the required shear connectors (e.g., headed studs, shear studs) based on the project requirements and code provisions.
Design the connection details between the steel beam and Verco floor deck, ensuring adequate strength and stiffness.
