Definition of dead load : a constant load in a structure (such as a bridge, building, or machine) that is due to the weight of the members, the supported structure, and permanent attachments or accessories. In reality, these loads do not typically take the form of uniform loads. The earthquake loadings magnitude will depend on the buildings mass or weight, dynamic properties, and contrasts in stiffness of adjoining floors, along with the earthquakes length and intensity. However, since the probabilities of occurrence for environmental loads are dierent from those due to the use of structures, the current codes use the term live loads to refer only to those variable loads caused by the use of the structure. . 13.
