Seismic Behaviour of Rammed Earth Dwellings Reinforced With Confinement Wood Frames and a Rigid Concrete Diaphragm
Abstract eng: Earth constructions have a wide presence all over the world represented in housing architecture and architectural heritage. A large number of these constructions are located in seismic regions and have a significant seismic vulnerability because of their structural features. Reinforcement alternatives have been proposed to improve their behavior and to prevent collapse. As a contribution to this purpose, this paper proposes an integrated strategy consisting in external reinforcement with wood elements on both sides of the walls of rammed earth construction and a rigid diaphragm by means of an upper concrete beam. This beam is proposed to be built with a smooth transition between the earth and the concrete to enhance compatibility. The results of shake table tests on a 1:6 scaled model and its unreinforced counterpart show a significant improvement in the global behavior of the construction, achieving the main goal of preventing collapse.
