Analysis of building circulation spaces for anti-terrorist security

The paper examines the principles underlying the design of the recreational and communication framework in public buildings and methods of ensuring its protection and anti-terrorist security. The requirements of the regulatory literature and guidelines for the protection of buildings and structures from terrorist attacks are briefly considered. Using individual examples, the basic principles of arranging a hierarchical structure of building spaces in terms of their protection are considered, options for zoning and dividing by access levels are presented, along with a description of techniques for protecting the nodal, most important points: entrances and main distribution spaces. The main architectural elements of the circulation framework that affect its protection from potential criminal encroachments are identified and classified. The author concludes that the spatial planning of the building's circulation framework and its vertical and horizontal connections is of prime importance in terms of safety and security.
