| Abstract |
The purpose of this study is to investigate the effects of composition of underground structural wall and H-pile in soil cement. The results
of previous experimental studies are re-analyzed and the nonlinear cross-sectional analyses of composite basement walls are performed to
verify their nonlinear flexural behavior. Based on the study, it is explained how the gap deformation between H-Pile and RC wall should be
considered in the design of flexure of composite underground walls. The nonlinear cross-sectional analysis shows that the load-displacement
curves of composite basement wall specimens exhibiting flexural behavior exist between the results of the analysis of the complete and
non-composite cases. When predicting the behavior of the composite basement wall by nonlinear cross-sectional analysis, the flexural behavior
of the composite basement wall could be suitably predicted by considering the reduction of the composite ratio due to tensile stress acting
on shear connectors. |
