Construction type va vs vb

What does VB mean in construction?
Type V — Wood Construction
A Type V-B construction, the most basic, does not require a fire resistance rating for any of the building elements.
The building elements are the primary structural frame, bearing walls, non-bearing walls, floor construction, and roof construction._{Jan 21, 2021}.
Group V-B: No required fire-resistance rating for any of the building elements.
It is the only type of construction that allows for combustible interior walls and structural components._{Mar 29, 2022}
VA represents the voltage at Node A, while VB represents the voltage at Node B.
These voltages are measured with respect to a common reference point or ground in the circuit.
The difference between VA and VB is the potential difference or voltage between the two nodes.
It is calculated as VB - VA.

TYPE VA (ISO 1): A wood-framed building. Protected construction having all major building elements with at least a 1-hour fire-resistance rating. Exception: non-load bearing interior walls and partitions having no rating. TYPE VB (ISO 1): A wood-framed building having no fire-resistance ratings.

Construction Type Classification

The different construction classifications are found in Section 602 of the International Building Code.
All buildings shall be classified in one of the five construction types which are defined in Sections 602.2 through 602.5.
To classify for a specific construction type, the building elements must have a fire-resistance rating not less than that s.

Things to Note

While you now have a better understanding of the Type of Construction classifications noted above, it is important to know that they are also further subdivided into two categories that are used to identify differences in the degree of fire resistance required.
These subdivided categories are as follows: IA and IB, IIA and IIB, IIIA and IIIB, VA an.

What Are The 5 Types of Construction?

The 5 types of construction classifications are:Type I, Type II, Type III, Type IV, & Type V.
Every building you see has been classified into one out of five types of construction.
Chapter 6 of the International Building Code (IBC) outlines the requirements to correctly classify a building by its type of construction.
