Abstract:
Reinforced wall structures and methods for strengthening wall structures to more effectively resist damage produced by seismically induced forces are disclosed. According to one embodiment, a method for strengthening a double wall structure comprises forming plural layers of a foamable, adhesive material in the cavity between the two wall portions of the double wall structure to bond together the wall portions. According to another embodiment, a method for strengthening a single wall comprises spacing a sheathing layer from one surface of the wall so as to define a cavity therebetween. A plurality of structural members are positioned outside of the cavity so as to support the inner form. A foamable, adhesive material is introduced into the cavity to bond together the inner form and the wall.
