Engineered wood structural system

An engineered wood structural system made of engineered wood components, wherein the engineered wood components include:

• at least one vertical structural element with several structural nodes on different vertical positions, corresponding to different floor levels, each structural node including at least one first seat;
• at least one horizontal structural element for each structural node, each horizontal structural element made up 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 second spacers comprised between said upper and lower horizontal boards, the at least one horizontal structural element including at least one second seat supported and vertically overlapped on the at least one first seat of the vertical structural element;
• wherein
• the at least one vertical structural element is made up of multiple continuous vertical struts continuous along an entire longitude of the vertical structural element separated to each other in a horizontal direction and rigidly connected to each other through first spacers comprised between said vertical struts, with the at least one first seat at least partially comprised between the vertical struts, the continuous vertical struts being made up of multiple successive vertical strut segments aligned and rigidly connected to each other;
• the at least one second seat is in a region of the horizontal structural element inserted between the vertical struts, in a hollow interior of the vertical structural element free of first spacers without interrupting the vertical struts.
