Most engineers and contractors dont worry too much about the wind load of small or large low-level buildings, but it will become a huge consideration when they start working on tall, high-rise buildings. The American Society of Civil Engineers (ASCE) requires that the minimum live load in the design should always exceed the maximum anticipated live load during the life span of the building in the Caseloads. Can you identify the cause of failure of this building? For example, the loading H20-44 represents a code for a twoaxle truck weighing 20 tons initially instituted in the 1944 edition of the AASHTO Specification. A typical roof is expected to support a live load of 20 psf; this minimum live load is in addition to the dead load that the roof must bear.

For Live load, you refer IS 875 Part II because it varying according to the usage of the building. The position of a live load may change, so each member of the structure must be designed for the position of the load that causes the maximum stress in that member. The 2016 edition of ASCE 7, which supersedes Standard ASCE/SEI 7-10, coordinates with the most recent material standards, including ACI, AISC, AISI, AWC, and TMS standards. Thermal load occurs when the materials contract or expand during temperature changes, while the settlement load refers to one area within the building that settles more than other sites. Also, soil load happens when too much water causes the soil to erode. Generally, the customary floor dead load is 10-12 PSF (pounds per square foot) for floors, 12-15 PSF for roof rafters and 20 PSF for roof trusses.
