## How do I define temperature loads on a composite beam?

The load case 'Temperature' is very important in composite structures. Here, it is necessary to distinguish between the load cases of warming from above (due to concreting) and warming from below. Since a temperature change has to be defined here, the load is defined as Delta T. Often, a composite beam is modeled by an eccentric member coupled to a surface. Therefore, the difference in temperature between these two elements (surface and member) must be divided.

The load on the member is defined as the member load with the temperature differential multiplied by the height of the member and divided by the total height of the composite cross-section ($\triangle T\times\frac{h_s}{h_g}$). If the top fibers of the member are colder than the bottom, the value must be defined as negative.
