Abstract [en]

Along with the technical and technological evolution of today’s modern society, comes a new range of threats on critical infrastructure such as the malicious use of explosives, fire arms, ramming with vehicles, arson, electromagnetic threats, chemical and biological weapons, and espionage. To maintain social security, a need of enforcing critical infrastructure to withstand the damage on withheld values caused by antagonist strikes is developed. The need of establishing enforcing measures is utterly important regarding the critical infrastructures pursuing democratic activities such as government agencies, embassies and residences of the head of states, amongst others. Establishing an adequate protection to the intended critical infrastructure brings up an issue with managing to enforce the existing façade and its framework, cornices, doors, windows and vents to make them resistant to the current threats. This master degree project aims to compile existing knowledge and suggest enforcing solutions based on building technology that take the current design in consideration and provides a structural protection to withstand stated threats. The aim of the work is fulfilled through a literature study, several interviews, the compilation of a risk index analysis and three representative types of artificial buildings with democratic purposes. The work results in several enforcing façade solutions that confirm existing researches discussing fortification and structural protection, and which creates an adequate protection against antagonist strikes ability to cause damage on withheld values in the building. In general, a façade construction is to be enforced with major thickness, density, elastic strength and air tightness. The work also leads to the discovery of several, never before officially compiled and scientifically researched enforcing façade solutions. When establishing enforcing measures to the façade of critical, democratic infrastructure it’s essential to create a structural protection that withstands the current threats while also being reasonable on possible actions, the effects on the building activity and financial maintainability. The structural protection created needs to work as a unity of façade, joists and attachments to ensure the building doesn’t collapse due to local damage. Regardless of the enforcing measures taken, there’s always going to be a risk on new kinds of threats evolving or antagonist strikes summoning up major resources than expected when designing the protection. With public buildings in urban areas it’s not practically or financially reasonable to establish a structural protection to resist every possible threat since the building also needs to be appealing, retain conservational values and ensure accessibility.
