# What Is A Transfer Load In Building Construction?

A transfer structure in building construction is a structure that alters the load path of the gravity loads, shifting the line of thrust laterally to a different vertical plane.

This allows for the redistribution of gravity loads, such as dead and live loads due to occupancy or snow, from the roof and upper floors down to the ground.

## What Are The Different Types Of Load Transfer?

There are two main types of load transfer: lateral load transfer and longitudinal load transfer. Lateral load transfer occurs during cornering and is the shift of mass across the wheels due to the centrifugal force and the lateral acceleration.

Longitudinal load transfer is the measurable change of load borne by different wheels during acceleration (both longitudinal and lateral).

Lateral load transfer can be calculated using a simplified equation that expresses it as a fraction of the total weight of the vehicle. Longitudinal load transfer can be calculated using equations that take into account factors such as longitudinal acceleration, slip angle, and slip ratio.

Lowering the center of mass towards the ground is one method of reducing both lateral and longitudinal load transfer.

Another method is to reduce tire loading on one end of a vehicle, which will reduce lateral load transfer. Pulling a sled also reduces friction experienced by the tires by transferring some of the load away from them.

Additionally, understanding how force angles affect suspension can help reduce or increase load transfer depending on what is desired.

## How Do You Calculate Load Transfer?

To calculate load transfer, divide the center of gravity height by the width of the contact patches, and then multiply that by the acceleration and weight of the vehicle.

Additionally, static mass on the left and right sides must be taken into account when calculating longitudinal load transfer.

Finally, for a slab-to-beam connection, one must calculate the total load over beams B1 & B2.

## How Is Load Transferred In the RCC Framed Structure?

In a framed structure, loads are transferred from the slabs to the beams, then to the columns, and finally to the foundation.

The load transfer mechanism in a framed structure starts with the slabs which flat horizontal surfaces are made with a combination of concrete and steel. A total load of a slab includes the Live Load, Floor Load, and Dead Load.

In two-way slabs, the load is transferred from the wall area by slab/beam function to vertical wind beams and then further to the gable foundation and roof area. Shear walls and frames are also used to transmit lateral forces from diaphragms.

In conclusion, the load transfer mechanism in a framed structure involves proper distribution and transmission of loads from one element to another until it reaches their final destination – the ground.

## How Is Load Transferred From Beam To Column?

Loads from a slab are transferred to beams through the geometrical dimension of the slab and the direction of reinforcements. In a one-way slab, the load is divided equally between adjacent beams, while in a two-way slab, each beam supports an amount of the load from the slab.

The distributed load on a beam is calculated by multiplying the segment area (trapezoidal or triangular area) by the slab’s unit load divided by the beam length.

In addition to loads from slabs, columns are also subjected to bending moments that must be taken into account in the design. Columns typically experience axial compressive stresses due to loads applied at their ends.

To calculate uniformly distributed load on a beam, divide its actual load distribution by its length in kilonewtons per meter
