Discussion of 'Axial Compression of Footings in Cohesionless Soils. I: Load-Settlement Behavior'

摘要

The discussers would like to commend the authors for their investigation of the characterization and parameterization of the load-settlement behavior of axially loaded footings on cohesion-less soils because of its importance in geotechnical practice. In this discussion, the discussers would like to: (1) provide the results of a comparative assessment of the performance of load-displacement models in approximating the results of a set of full-scale load tests on large footings; (2) stress the importance of investigating load-displacement uncertainty by addressing quantitatively not only second-moment statistics of model parameters but also the correlation between the parameters themselves; and (3) examine the adequateness of load-displacement models for the generation of multivariate distributions for simulation purposes.
