Conclusions and Recommendations
This chapter summarizes the methodology and typical results of the (1) experimental investigations, (2) numerical analyses, and (3) parametric studies conducted to investigate the thermal soil structure interaction of Rigidly Framed Earth Retaining Structures (RFERS). Recommendations for the design of such structures are also presented.
Comparison of the lateral displacement and corresponding earth pressures as well as structural stresses developed at the backfill stage in the absence of temperature changes, and those after the application of thermal movements, suggests that structural frames designed without the inclusion of the soil-structure interaction effects due to temperature changes will likely undergo undesirable response in service.
Preliminary recommendations regarding the analysis and design of RFERS at back fill stage and due to exposure to thermal cycles are also made in this section.
