Table 4: Partial Safety Factors (According To IS: 800 (2007) )

The document contains a table listing partial safety factors for different types of buildings according to IS: 800 (2007). It provides maximum deflection limits for building elements under various loading conditions such as live load, wind load, and crane load. The table specifies deflection limits for structural members like purlins, girts, rafters, columns, floors and roofs based on whether they support elastic or brittle cladding. It also provides lateral deflection limits for building elements under combined crane and wind loads.
