Modified-thermal borehole shear test device and testing procedure to investigate the soil-structure interaction of energy piles

Xiao, Suguang; Suleiman, Muhannad T.; Naito, Clay; Al-Khawaja, Mohammed ( ASTM International , 2017 , Article)

The intermittent operation of heat pumps connected to energy piles causes cyclic variation of temperature in the pile and surrounding soil, affecting the soil-pile interaction in ways that have not been fully investigated ...

Soil-concrete interface properties subjected to temperature changes and cycles using direct shear tests

Xiao, Suguang; Suleiman, Muhannad T.; Elzeiny, Rehab; Xie, Huan; Al-Khawaja, Mohammed ( American Society of Civil Engineers Library (ASCE Library) , 2017 , Conference)

Geothermal foundations (energy piles) combine the structural function of deep foundations with the ground source heat exchangers to transfer geothermal energy to superstructures. The intermittent operation of the geothermal ...
