Resumo(s): | Among the building techniques based on the use of raw earth as building material, rammed earth is one of the most used construction materials across the world. Rammed earth structures are characterized by low resistance against extreme loading, such as during earthquakes. Basing on the efficacy of Textile Reinforced Mortar (TRM) for masonry structures, the use of low-cost mesh embedded in earth-based mortar is proposed as a strengthening technique for rammed earth heritage. The base materials were characterized, namely soil, earth-based mortar and two type of mesh (nylon and glass fibre). Subsequently, eight walls were cast using the characterized soil and reinforced with glass fibre TRM (GRE) and nylon TRM (NRE). To assess the efficacy of the TRM, diagonal compression tests were performed and the shear strength and shear stress were evaluated and compared with the unreinforced walls. Digital image correlation (DIC) was implemented to investigate the crack pattern. The results demonstrate that TRM improves the shear performance of the rammed earth walls in terms of shear strength and shear strain. |
