The provisions contained within ASCE 7-10 for determining the wind loads on rooftop equipment on buildings is limited to buildings with a mean roof height h ≤ 60 feet. 3), which are the basis for the crane calculations, can be significantly exceeded. In addition,. The process includes identifying the applicable. Introduction on Load Combinations of Concrete Design : A load combination results when more than one load type acts on the structure. the full wind loads in both along- and across-wind direc-tions simultaneously (ASCE 7-10, NBCC 2010). Being able to read a Demag load chart properly provides you with a proper knowledge of your cranes potential lifting capacity. In ASCE/SEI 7­16, the load combinations with seismic load effects have been removed from ASCE/SEI Chapter 12 and placed in ASCE/SEI Chapter 2 in sections sepa­ rate from the basic load combinations. Less Labor - One crane system with one operator can replace multiple forklifts proving cranes to be more efficient.
