Structural Responses and Finite Element Modeling of Hakka Tulou Rammed Earth Structures

Hakka Tulou, rammed earth structures in Fujian Province, China, have demonstrated remarkable structural resilience and thermal comfort over centuries. A study combining material testing, nondestructive analysis, and finite element modeling revealed that these ancient buildings, despite their age, remain structurally sound, even surviving strong earthquakes that modern constructions often fail to withstand. The research also debunked the myth of self-healing cracks but suggested that lime in the rammed earth may enable minor autogenous healing. Additionally, the high thermal mass of the walls, combined with shading, provides consistent thermal comfort by delaying heat release. These findings highlight the potential of rammed earth as an environmentally friendly and efficient construction material, capable of earning top LEED green building certification.
