a quantitative study on the resilience of hospitals and medical centers-case study of madani hospital in karaj

One of the main challenges of this century for high-seismic cities is to prepare for natural disasters, especially earthquakes to reduce the vulnerability and increase seismic resilience. seismic resilience indicates the ability to maintain a level of functionality or performance of a building, bridge, lifeline network, or community over a specified period of timedetermined as a tlc or control time (figure 1). resilience is defined geometrically as a normalized shaded area below the functional diagram of the system, determined as q(t). q(t) is an invariant stochastic process that is measured as a percentagein terms of the dimensionless function of time.
