Engineered wood structural system

An engineered wood structural system made of engineered wood components, the system comprising:

• at least one vertical structural element with several structural nodes located on different vertical positions, corresponding to different floor levels;
• multiple horizontal structural elements, each horizontal structural element comprised of an upper horizontal board and a lower horizontal board facing each other, separated to each other in a vertical direction and rigidly connected to each other through spacers positioned between the upper and lower horizontal boards;
• wherein the multiple horizontal structural elements of a same floor level are supported on a same structural node of the several structural nodes and are rigidly connected to each other through an upper connector at least partially overlapped, and attached, to all the horizontal structural elements supported on the same structural node to transfer horizontal traction loads between the upper horizontal boards of the connected horizontal structural elements;
• and
• the multiple horizontal structural elements supported on the same structural node are also rigidly connected to each other through a lower connector located between the horizontal structural elements converging in the same structural node and in close contact therewith to transfer horizontal compression loads between the converging horizontal structural elements.
