What is the current IBC Code?

IBC Development The International Code Council (ICC) promulgates a new International Building Code every 3 years through the ICC Code Development Process. As such, the current version of the IBC is the 2021 edition, also known as ICC IBC-2021.

What are the IBC construction types?

The IBC’s Five Types of Construction

• Type I: Fire Resistive.
• Type II: Non-Combustible.
• Type III: Ordinary Construction.
• Type IV: Heavy Timber.
• Type V: Wood Frame Construction.
• Other Rules in Chapter 6.

What is an IBC class?

IBC 101 is designed for code officials, inspectors, contractors, and design professionals, but open to any interested party. This five-day course provides comprehensive instruction and illustration on the use, application, intent and rationale of the 2009 International Building Code (IBC).

What is prescriptive fire-resistance?

Under the prescriptive fire-resistance requirements of this code, the fire-resistance rating of a building element, component or assembly shall be established without the use of automatic sprinklers or any other fire suppression system being incorporated as part of the assembly tested in accordance with the fire …

What is the difference between ICC and IBC?

The International Building Code (IBC) is a model building code developed by the International Code Council (ICC). The IBC addresses both health and safety concerns for buildings based upon prescriptive and performance related requirements. The IBC is fully compatible with all other published ICC codes.

Does IBC apply to residential?

IBC: The International Building Code contains regulations about practices used in commercial construction. IRC: The International Residential Code contains information and regulations applying to residential construction, including both new construction practices as well as remodeling issues.

What is the difference between type 2a and type 2b construction?

Construction Types IIA and IIB are also noncombustible, but have little to no fire resistance. Type IIA has a minimum of 1 hour fire resistance throughout. Type IIB, although noncombustible, has no requirements for fire resistance, unless required by other sections of the code.

What is Type 3 Construction?

TYPE III – This type of constructed building is also called a brick-and-joist structure by some. It has masonry-bearing walls but the floors, structural framework, and roof are made of wood or other combustible material; for example, a concrete-block building with wood roof and floor trusses.

What occupancy is a church?

Assembly (Group A) – places used for people gathering for entertainment, worship, and eating or drinking. Examples: churches, restaurants (with 50 or more possible occupants), theaters, and stadiums.

What is the difference between a fire barrier and a fire partition?

The term “fire barrier” refers to a structure that has, at minimum, a one-hour fire resistance rating. By comparison, a “fire partition” must have at least a 30-minute rating for certain types of occupancies. Otherwise, a fire partition must have a one-hour rating.

How do you determine fire-resistance?

Fire-resistance ratings are determined by testing a mock-up structural assembly according to procedures in the American Society for Testing and Materials (ASTM) E119 Standard Test Methods for Fire Tests of Building Construction and Materials, available at www.astm.org The test also is known as NFPA 251, Standard …

What are the provisions of the IBC chapter 701?

701.1 Scope. The provisions of this chapter shall govern the materials, systems and assemblies used for structural fire resistance and fire-resistance-rated construction separation of adjacent spaces to safeguard against the spread of fire and smoke within a building and the spread of fire to or from buildings. 701.2 Multiple use fire assemblies.

What does IBC 703.2.4 supplemental features mean?

703.2.4 Supplemental features. Where materials, systems or devices that have not been tested as part of a fire-resistance-rated assembly are incorporated into the building element, component or assembly, sufficient data shall be made available to the building official to show that the required fire-resistance rating is not reduced.

What are the exceptions to the IBC 707.5?

Exception: Fire barriers, fire partitions, smoke barriers and horizontal assemblies as provided in Sections 707.5, 708.4, 709.4 and 711.2, respectively. 704.2 Column protection.

What does IBC 703.2.1 fire resistance rating mean?

703.2.1 Nonsymmetrical wall construction. Interior walls and partitions of nonsymmetrical construction shall be tested with both faces exposed to the furnace, and the assigned fire-resistance rating shall be the shortest duration obtained from the two tests conducted in compliance with ASTM E119 or UL 263.
