The Hardened Structures Engineering team provides the following building “hardening” services to meet your damage mitigation expectations:
The Hardened Structures team provides a detailed survey to determine and record current structural integrity, barriers, detection systems, operational, logistic, and security requirements, roads, landscaping, and other features. This initial site survey information must be integrated and coupled with the appropriate building “Hardening” design and planning to provide the necessary client specific level of protection (see chart below) for critical asset protection
|Level of Protection||Potential Structural Damage||Potential Injury|
|Below Standard||Severely damaged. Frame collapse/massive destruction. Little left standing||Majority of personnel suffer fatalities|
|Very Low||Heavily damaged. Onset of structural collapse: Major deformation of primary and secondary structural members, but progressive collapse unlikely. Collapse of non-structural elements||Majority of personnel suffer serious injuries. There are likely to be a limited number (10% to 25% fatalities)|
|Low||Damages - unrepairable. Major deformation of non-structural elements and secondary structural members and minor deformation of primary structural members, but progressive collapse unlikely||Majority of personnel suffer injuries. There may be a few (<10%) fatalities|
|Medium||Damaged-repairable. Minor deformations of non structural elements and secondary structural members with no permanent deformation in primary structural members||Some minor injuries but fatalities are unlikely|
|High||Superficially damaged. No permanent deformation of primary and secondary structural members and non-structural elements||Only superficial injuries are likely|
Steel Blast Connectors
Explosive blast events require an understanding of loading and responses that occur in milliseconds. When considering structural framing systems, it is critical to coordinate ALL of the design assumptions regarding blast weights/loads, blast locations, and façade design requirements.
Blast Curtain Wall Installation
In any conventional designed building, the component most vulnerable to blast loads is the building envelope. Hardened Structures team understands what makes these wall systems so vulnerable and uses many concepts to “HARDEN” the building facade.
