Partial factors and non-linear ground–structure interaction
Challenges associated with the application of partial factors to non-linear ground–structure interaction were studied for some case history examples. For some nonlinear ground–structure interaction systems, the selection of geotechnical strength parameters for calculating the movement at service condition can be important but problematic. In the calculation of action effects for structural strength design, the application of partial factors needs to simulate the trigger or path to various modes of instability, both geotechnical and structural. To avoid inconsistency, the partial factor for the self-weight of soil that is part of the interaction system needs to be set at unity. For some complex soil–structure interaction systems, the design action effects on a structural element depend on the potential failure mode examined.
期刊介绍:
The objectives of the Association shall be the promotion of co-operation among geotechnical societies in SE Asia; and the assistance to member societies who have limited number of members. Now there is only one combined web titled: AGSSEA-SEAGS. SEAGS & AGSSEA encourage the submission of scholarly and practice-oriented articles to its journal. The journal is published quarterly. Both sponsors of the journal, the Southeast Asian Geotechnical Society and the Association of Geotechnical Societies in Southeast Asia, promote the ideals and goals of the International Society of Soil Mechanics and Geotechhnical Engineering in fostering communications, developing insights and enabling the advancement of the geotechnical engineering discipline.
