This can be accredited to its various properties such as providing lateral bracing
and withstanding wind and building loads coupled with the increasing demand for green building materials.
This contract also includes the lateral bracing
of existing perimeter foundation walls in preparation for a new building foundation system, which will be installed under a separate contract.
The entire building is designed as a seismic risk category IV structure with enhanced lateral bracing
and passive survivability.
Civiltech engineer Greg Hatlestad wrote in a report that as the truck went through the bridge from the west, it knocked off the timber cover and its lateral bracing
. Other damage included cracking and splitting of timber posts on the bridge's west side.
"The work was done when the mall was closed and was all accomplished from removal of the lateral bracing
, lifting of the roof in several stages, and installation of the temporary lateral bracing
prior to the opening of the mall on Monday."
First, the stress states in the lateral bracing
members are presented, and then, the behavior of the spring is discussed.
According to the ANSI/AISC358-10 , supplemental lateral bracing
(SLB) has to be located in the range of 0.5h from the end of the RBS that is farthest from the column face (Figure 1(c)).
In divergent conventional braces, I-shaped sections are used for building linking beam piece that requires lateral bracing
to prevent lateral torsional buckling (that's why in the bridge piers and towers, this system is not used against lateral loads).
(ii) Increasing the Stiffness of Both Building by Adding Shear Walls: Since distance between the buildings cannot be increased due to high cost of land and construction difficulties, increasing the stiffness of one or both buildings by providing the shear wall or lateral bracing
in such a way it reduce the lateral displacements which can be accommodate between provided seismic gap/separation distance.
The typical failure of prefabricated roof truss assemblies is the direct result of contractors' failure to provide the required lateral bracing
necessary to prevent buckling and collective collapse, as is frequently found during forensic examination of collapsed structures.
The timber ribs are tied back to the building's concrete frame by a secondary steel structure and lateral bracing
is provided by a cat's cradle of tensile wires.
