When the capstone and top horizontal construction have been installed, the connection of the two vertical segments of the geometry completes the closed structural circuit of the trapezium structure. The structural vertical element may now be constructed. The structure is now a stable, load-carrying mechanism. The inward bending moments are stabilized and the closed circuit of the completed geometry alters the load paths of the structure. The gravity loads will follow the load paths through the angular roof structure and be supported by the vertical walls at the base of the system. This action of load resistance of the truss action, however, creates an outward horizontal force at the spring line. The lower thrust beam now reverses the nature of its stress from a compression member and becomes a tension member, resisting the outward movement on each side. The bonded embedment of the timber thrust beam into the concrete wall resists the tension “pull out” action caused by the horizontal vectors at the spring line. The lower walls react to transmit vertical loads, and the thrust beam is now a horizontal tension member. The two components combine to resist the vertical and horizontal vectors of the truss. The composite walls and the thrust beams now complete the closed circuit that develops a stable structure.
