Using a CPT and laboratory test database compiled for statistical analysis of such data, it is demonstrated why the Hierarchical Bayesian modelling approach...

... ABSTRACT: Back analysis of monopile driving records is important for understanding the foundation behaviour during driving, optimising the installation procedures and reducing installation related risks. A database has been developed that includes almost 700 monopiles from 13 offshore sites...

... to driving (SRD) which leads to mismatches in computed blow counts when compared to actual driving records. Almost 700 monopile driving records have been compiled in a database and back calculated based on standard industry SRD methodologies. A new SRD methodology is developed based on the database which...

... for sands which is based on careful calibration to a quality assured pile-test database compiled as part of an international Joint Industry Project (JIP). This new CPT based method gave broadly similar capacities to the existing ICP-05 and UWA-05 methods for the assembled Unified database but delivered less...

... ABSTRACT: A database was developed of resonant column tests to characterize the shear modulus (G) and material damping ratio (D) at small shear strains (10 −5 % to about 0.1 %), and strain-controlled cyclic direct simple shear tests to evaluate the decrease of G and the increase of D at large...

Further calibrations have been made to this new database to improve the performance of the model. 1 Introduction Analysis of piles under lateral loads utilizing p-y springs, has been the principal approach utilized by the industry for decades...

... ABSTRACT: Given the popularity of the p-y approach to model laterally loaded piles, this paper evaluates the predictive performance of six existing p-y approaches for piles in sand against a new database of lateral pile tests comprising driven and vibrated piles with a range of aspect...

... in dense sand. 1 Introduction The new ISO/API design method (Lehane et al., 2020) has changed how driven piles under axial loading are designed offshore. To calibrate the design method, high quality static load tests were compiled (Lehane et al. , 2017), building on previous databases such as the ZJU...

Virtually no measurements of the axial capacity of a driven pile with the dimensions relevant to new offshore develop- ments exist.
