Reconfigurable precast concrete construction system

A method of assembling a building structure, the method comprising:

• orienting a convex side of a structural module toward a common axis and orienting a concave side of the structural moule away from the common axis;
• coupling and arranging at least two structural modules to define a member element, the member element having a first end and a second end;
• and
• assembling a post-tensioning assembly by:
• (i) coupling at least two anchors to the member element at distinct locations at or between the first end and the second end, and (ii) coupling a tensile element to the at least two anchors in a manner providing a post-tensioning force between the at least two anchors and along the common axis.

An apparatus for use in a building structure, the apparatus comprising:

• means for interconnecting structural modules in a manner that enables reversible construction;
• means for assembling a member element with the at least two structural modules;
• and
• means for applying post-tensioning for maintaining structural integrity of the member element.
