Design of civil air defence work is different to general civil. load are occasional moments of civil air defense role, the role of the number usually only once, load value is particularly large, but uncertain. Therefore the design of safety or capacity of reserve requirements can be reduced, material design strength can be increased, allowing structural design load is reached when the plastic strain state of a larger deformation and fracture, or even partial destruction, it must be to prevent collapse and has the necessary maintenance functions. Therefore, the civil air defense engineering requirements for building materials not only strength but also high ductility, high energy capacity and impact resistance. |
