Economic Pier-to-Pile Connections for Permanently Cased Shaft (CFST) Piles
| 项目名称： | Economic Pier-to-Pile Connections for Permanently Cased Shaft (CFST) Piles |
| 摘要： | A missing piece of this new structural system is the foundation system including the direct pier-to-pile connection and the contribution of soil-structure interaction on this is an economical solution that reduces the cost of the structural foundation system. The overall goals of the proposed research are to: (1) Investigate concrete-filled steel tubes (CFST) connections and other column-to-pile connections through a literature review. (2) Select column-to-pile connections for study based on the finite element analysis (FEA) results. (3) Investigate the seismic response and resilience, including damage, of selected CFST connections using large-scale testing. (4) Develop, in collaboration with WSDOT and Caltrans as well as other interested transportation agencies, new design methods for these connections. (5) Develop a simplified nonlinear spring element to simulate the connection and pair the engineering demand parameters from the model to the damage states to provide tools for PBEE. |
