Bearing Capacity of Rocks - IIT Kanpur
home.iitk.ac.inIn case of rock mass with favorable discontinuities, the net allowable bearing pressure may be estimated from: q a = q c * N j Where qWhere q c = average uniaxial compressive strength of rock coresaverage uniaxial compressive strength of rock cores N j = empirical coefficient depending on the spacing of the discontinuities 3+S/B 10 []1+300(δ/S) δ= thickness of …
CALCULATING WIND LOADS ON LOW-RISE STRUCTURES PER …
www.awc.orgShear wall overturning forces are resisted by the structure’s dead load and by supplemental hold down connections. Implicit in the assumption of a “box-like” structure is a roughly rectangular shape, relatively uniform distri-bution of shear resistance throughout the structure, and no significant structural discontinuities. In addition, the
