Experimental and Numerical Study of Enhancing the Seismic Behavior of Rammed Earth Buildings

Abstract:

Rammed earth structures are widely used as farmers dwellings in the southwest of China, however, they are extremely vulnerable to earthquake loadings. An economic, environmental-friendly and less-intervention seismic retrofitting technique is required to reinforce these dwellings so as to increase regional seismic capability. A preliminary laboratory testing was conducted to investigate the enhancement of the seismic behavior of the rammed earth wall with externally bonded fibers. Different retrofitting materials and adhesives were tested to characterize their mechanical properties and bonding performance when externally glued on rammed earth blocks. The most suitable and practical retrofitting material and adhesive were chosen based on the experimental results. Furthermore, a numerical analysis was performed to investigate the improvement of the shear capacity of the rammed earth wall with the proposed technique. It was verified that the proposed retrofitting technique is a promising option for seismic retrofitting of rammed earth walls.
