Loads are not easily transferred through structural members to the foundation and dispersed to the ground. Without such transfer, forces such as wind loads and seismic loads produce lateral loads, causing buckling, racking, and shear. The introduction of diagonal bracing, shear walls, and diaphragms attempts to counteract lateral loads.
Once diagonal bracing was introduced, the structure became significantly stiffer against racking and swaying, which typically causes cracking in walls and siding and causes the structure to weaken dramatically. Diagonal members resist lateral forces by axial tension and compression. First, only one diagonal member was introduced on each side. As diagonal members increased, the structure became significantly stronger in the longitudinal direction, while the transverse or shorter cross section remained weak and bent under applied loads.
A core acting as shear walls was added to provide resistance in both the longitudinal and the transverse axes. These shear walls provide the additional bracing needed to stabilize forces in the transverse axis, transferring loads more effectively to the foundation.
The addition of diaphragms provided a significant increase in stiffness throughout the entire structure. Lateral loads were transferred more effectively in both the longitudinal and transverse axes. Though the structure resisted both shear and bending in its own plane, the structure continued to experience racking.
In conclusion, each lateral loadresisting system provided a portion of the transfer needed to stabilize the structure against shear, bending, and racking. In order to further combat racking, diagonal bracing was introduced also on the ends of the upper plane, shown in yellow. The connection of the diaphragm system to the shear-wall core aided in the transfer of lateral forces.
