Dynamic bearing capacity

WebApr 26, 2012 · Abstract. Design of foundations in earthquake prone areas needs special considerations. Shallow foundations may experience a reduction in bearing capacity and increase in settlement and tilt due to seismic loading. The reduction in bearing capacity depends on the nature and type of soil and ground acceleration parameters. In the case … WebThe bearing capacity factor, N q, ... The greater is the penetration of the pile per blow, the lesser will be the load resistance capacity of the soil. Dynamic formulae have been developed on the basis of this principle, considering additional factors such as: 1. Elastic compression of the pile.
