Understanding Material for Construction
This may be one of the more boring not so visually apparent entries. Here Im presenting the documentation I have found in regards to specific questions I had about construction material, such as; how much does a 2x4x8 weight? how much weight can a 2x4x8 support? how heavy are my wall going to be?
The loads considered for a building are divided into two major categories; dead loads and live loads. Dead loads are associated with the building and do not change magnitude or location. It includes the weight of the building components, structural parts, and also any fixed equipment such as plumbing, electric, heating, ventilating, refrigeration, and sprinkler systems. Live loads change with time and include loads caused by people, animals, grain, potatoes, equipment, manure, etc.
