Model Building Codes
The UBC, BOCA and CABO have and will approve SBS engineered building systems on an individual, case-by-case basis. No specific report or approval is required. ICBO evaluation is available.
SBS type panels have been tested and approved by various domestic and foreign educational and testing agencies, and were found to successfully surpass all known criteria.
These building systems have been tested and approved for most applications and occupancies. Please ask us about your application and fire assembly for a specific answer. Testing also supports the data for these fire resistant assemblies.
SteelCrete ICBO/ICC Approvals Not Required
1. The SteelCrete system design capacities for both in-plane and out-of-plane loading are based upon sound and straightforward engineering principles and can be found in the UBC under Section 1923 Anchorage to Concrete. The following is how the SteelCrete system is designed as conventional construction found in the code:
A) The tabs that are punched from the light gauge studs and track behave as embedded 'J' bolts or Nelson Studs in the concrete. Standard 'J' bolt equations in the 1997 UBC have been used to establish allowable loads for both shear and tension.
B) The strength of the tabs is determined using the latest AISI standards for shear, tension and shear rupture capacity.
C) The typical design for vertical loads uses only the structural properties of the light gauge metal studs. Out of plane lateral loads are carried by the composite section where the concrete is in compression and by the metal stud only when the concrete is in tension.
D) The typical shear wall application in plane loads are carried to the concrete by the tabs in the top track flanges. The in plane loads are then carried by the concrete skin as a shear wall meeting all the requirements of the code. The loads are then transferred to the bottom track by the tabs.
E) The composite strength of the SteelCrete system is established through transformed section properties and is governed by stud size, stud and track gauge and the thickness and compressive strength of the concrete.
2. Per section 104.2.8 Alternate Materials, Alternate Design and Methods of Construction of the 1997 UBC Volume 1, the SteelCrete system is allowed upon acceptance of the Building Official. The following is an excerpt from the referenced code section:
A) The provisions of this code are not intended to prevent the use of any material, alternate design or method of construction not specifically prescribed by this code, provided any alternate has been approved and its use authorized by the Building Official.
B) The Building Official may approve any such alternate, provided the Building Official finds that the proposed design is satisfactory and complies with the provisions of this code and that the material, method of work offered is, for the purpose intended, at least the equivalent of that prescribed in this code in suitability, strength, effectiveness, fire resistance, durability, safety and sanitation.
C) The Building Official shall require that sufficient evidence or proof be submitted to substantiate any claims that may be made regarding its use. The details of any action granting approval of an alternate shall be recorded and entered in the files of the Code Enforcement Agency.
