Thats why engineers, architects, and the entire construction team need to work together and create a structural design that considers how much load it will experience every day. Dead loads also include the loads of fixtures that are permanently attached to the structure. 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. Workers calculate each structures dead load by the sections volume multiplied by the unit material weight. Live loads are those loads produced by the use and occupancy of the building or other structure and do not include construction or environmental loads such as wind load, snow load, rain load, earthquake load, flood load, or dead load.
