This process offers many benefits compared to the traditional home construction process, however, it also has a few drawbacks that are worth considering. Rather than being built on-location, modular homes are constructed one room at a time in a controlled factory then assembled on-site using cranes to lower the modules into place. How modular homes are constructed, though, is very different from the conventional home construction process. Once their construction is complete, modular homes look almost identical to their traditional counterparts. Conventional Homes: What’s the Difference?Īs we’ve mentioned, the difference between a modular home and a conventional home isn’t something you are likely to notice at a glance. In this article, we’ll detail the construction process of a modular home compared to a conventional one and discuss the two designs’ pros and cons to help decide which type is the best fit for you and your family. That’s because the primary difference between modular homes and conventional homes isn’t how they look or how they are laid out but rather how they are built. However, when searching for homes, if you don’t know what to look for, then there’s a chance you might not even notice that you are looking at a modular home. The strap beam is reinforced with prime reinforcement at top among the columns and at bottom under the interior footing.As trends continuously change, modular homes have grown increasingly popular. The footing is exposed to one-way bending.
The strap should be sufficiently connected with both the column and the footing through dowels in order that the footing and the strap function as unit. Normally, the strap weight is not taken into consideration in the design. Strap should not be in touch with soil in order that there are no soil reactions. The footing should be uniform for maintaining roughly equivalent soil pressure and getting rid of greater variations in B to minimize differential settlement. This inflexibility is required to manage rotation of the exterior footing. Strap should be inflexible – possibly Istrap/Ifooting > 2. The following basic concepts are required for making the design of strap footing :. The two columns are set by two individual footings attached with a inflexible beam known as ‘strap beam’. This type of footing is ideal for two columns.

The strap can transfer the moment resulting from an eccentricity to the internal column footing in order that a consistent soil pressure is developed under both footing.
The purpose of a strap footing is to attach an eccentrically loaded column footing to an internal column. To simplify the construction process, normally the bottom surfaces of the exterior footing, the strap beam, and the interior footing are kept at equivalent elevation, but the thickness of each element varies based on the strength requirements. It is suitable where the span among columns is greater and a normal combined footing can’t be provided because of the required large excavation. The issue can be resolved by attaching this footing with the adjoining interior footing through a strap concrete beam. When a property line subsists at or adjacent to the edge of an external column, a normal isolated footing is arranged eccentrically under this column and it has a tendency to tilt. It facilitates to allocate the weight of either heavily or eccentrically loaded column footings to adjoining footings.Ī strap footing normally supports two columns. This type of beam is known as a strap beam.
