A reversible joint includes male and female components. The male component has a rigid stud with a shaft region and a head region having a greater width, than the shaft region. The female component includes a polymer-based bushing including a polymer sleeve and an embedded heating element. The polymer sleeve is formed from a shape memory polymer (SMP) or an SMP composite and includes a central channel. The polymer-based bushing is capable of being activated by heating with the embedded heating element to reversibly render the polymer sleeve elastic and allow deformation of the central channel to an expanded channel width during insertion of the head region. The polymer sleeve becomes rigid after deactivation of the polymer-based bushing for retention of the male component. Load bearing assemblies formed by connecting modular structures with the reversible joint are also provided along with installation tools for the same.
