Stresses of Thermal Loads

By | Blog, Resources, Uncategorized | No Comments

A thermal load is defined as the temperature that causes the effect on buildings and structures, such as outdoor air temperature, solar radiation, underground temperature, indoor air temperature and the heat source equipment inside the building.

ASCE 7-15 section 2.3.5 and 2.4.4 specifically mention thermal and other self-straining loads are to be considered, where applicable. For many cases, thermal movements cannot be restrained and instead designs need to allow for the structure/equipment to move thermally otherwise stresses in either the restraints or in the structure/equipment may cause catastrophic failures.

The proper design of bridge overhang brackets and related falsework is critical. Failure to properly design this falsework can result in partial collapse of the formwork/falsework, damage to the bridge structure and damage to equipment.

Typical bridge construction requires the use of falsework to support workers, the outer edge of the concrete bridge deck, deck screed and sometimes the weight of the concrete barrier.
