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 said upper and lower horizontal boards;
• wherein the multiple horizontal structural elements of a same floor level are comprised of laterally adjacent slabs connected to each other through a perimetral region of the upper horizontal board of a first said laterally adjacent slab adhered to a perimetral region of the upper horizontal board of a second said laterally adjacent slab such that the upper horizontal boards of the laterally adjacent slabs are directly connected to one another, through complementary staggered steps or through a joint connector adhered on the perimetral regions of the upper horizontal boards connected to each other, to transfer horizontal loads between the upper horizontal boards of adjacent said horizontal structural elements.
