A strap footing is a component of a building's foundation. It is a type of combined footing, [1] consisting of two or more column footings connected by a concrete beam. This type of beam is called a strap beam. It is used to help distribute the weight of either heavily or eccentrically loaded column footings to adjacent footings. [2]

Out of the three types of strap footing, we discussed in this article, the most common type is the strap beam connecting the inner column. Why do we need Strap Footing? This is a type of foundation considered as a combined footing and shallow foundation constructed to manage the load eccentricity.

Apr 4, 2021 · Strap footings or cantilever footings are a special form of combined footings. They consist of two separate bases that are connected (balanced) by a strap beam. In the design of strap footing, it is assumed that the strap beam is rigid and does not transfer any load by bearing on the soil at its bottom contact surface.

A strap footing is usually analyzed as a beam in the longitudinal direction. The factored shear and moment diagrams help to visualize the variation of the internal forces along the strap footing, and therefore the required strengths.

This connecting bar or beam is called strap beam or strap footing. It is utilized to help disperse the heaviness of either intensely or whimsically stacked segment footings to nearby footings. The objective is to have a uniform bearing pressing factor and to …

Sep 6, 2023 · A strap footing consists of two independent bases joined together by a strap beam. Read on to learn more about the types of strap footings and their uses.

What Is Strap Footing? A strap footing is necessitated when a certain column footing has to be restricted in width due to unavoidable interference or boundary limitation. It is a type of combined footing and also known as cantilever footing.

Nov 18, 2020 · When a beam relates the independent footings of columns, it is referred to as a strap footing. It is used while the space between the columns is adequate that a combined trapezoidal footing becomes relatively slender, with high bending moments.

Aug 28, 2023 · To counteract this effect a strap beam is used to connect the exterior footing to a nearby interior footing. Thereby restraining the exterior footing from overturning from the high, induced eccentricity.

Apr 29, 2018 · A strap footing also known as cantilever footing, is a special case of combined foundation in which two separate footings are tied together by a beam called tie beam or strap beam.
