Types of load in steel structure
There are mainly five types of load, which are considered while designing a steel structure. They are - Dead loads, live/imposed load, wind load, snow load and earthquake load. In this article, a brief introduction of different types of load is given. Dead load (DL) It is the self - weight of structure. It is calculated by volume of each section multiplied with unit weight. Complete details of dead loads is given in IS:875(part-I)-1987. Live/imposed load (LL or IL) It varies in magnitude and in positions. It is applied on the structure temporarily. It depends on the intended use of the building. Related to IS:875(part-II)-1987. Wind load (WL) It is the horizontal load caused by movement of air relative to the earth. Essential to consider when the height of building exceeds two times the dimensions transverse to exposal wind surface. Depends upon velocity of wind and size of building. Related to IS:875(part-III)-1987. Snow load (SL) Vertical loads in the building. Considered only in th
