Geometry of the structure is the arrangement of dimensions, shapes and mutual positions of load-bearing elements in a building structure. The concept is fundamental when it comes to house design, as the geometry determines how loads are transferred throughout the system.
It determines the lengths, heights, angles and spacing of elements such as beams, columns, walls or roof trusses. Geometrical parameters directly influence the static working of a structure. Changing the span, section height or inclination angle of an element can change the distribution of forces and deformations.
The geometry of the structure also determines the stability of the system, the load-bearing capacity and the way in which the components are assembled. It is determined by designers at the stage of static calculations and technical documentation. In practice, the concept also includes execution tolerances, which define the permissible deviations from the designed dimensions. This ensures that the structure retains its intended load-bearing capacity and that the components work together correctly.
