Application of the Cone Penetration Test (CPT) for the evaluation of seismic performance isreviewed and updates presented. The role of the CPT in geotechnical earthquake engineering is presented.The use of the CPT to identify soil behavior type and the normalization of CPT parameters is also reviewedand updates presented. The case-history based method to evaluate the resistance of sand-like soils to cyclicloading is reviewed and compared with the expanded and re-evaluated case history database. The laboratory based method to evaluate the resistance of clay-like soils to cyclic loading is reviewed and modified for appli-cation using the CPT. A new combined CPT-based method to evaluate the resistance to cyclic loading is pro- posed that covers all soils and is evaluated using an expanded case history database. The CPT-based methodis extended to estimate both volumetric and shear strains for all soils and evaluated using the expanded casehistory database
