Buildings left standing in Turkey offer design guidance for future ... (The Conversation AU)

The damage to buildings designed under a life safety goal was so extensive that thousands had to be [US$32 billion](https://www.bloomberg.com/news/articles/2013-04-28/christchurch-quake-rebuild-soars-33-to-nz-40-billion-key-says#xj4y7vzkg), not accounting for inflation, of which $24 billion was construction costs. Buildings following a life safety objective are engineered to sustain damage in a controlled way, to keep the building standing and protect those inside. A soft story is a level that is significantly more vulnerable to lateral earthquake forces than the other stories in a multistory building. Much of the damage in Turkey occurred in nonductile concrete buildings constructed under a pre-1998 Turkish building code. Buildings designed under old codes can be strengthened to meet a life safety performance threshold. The older nonductile buildings also tended to have poorly arranged steel reinforcements, leaving them vulnerable to the sudden collapse of building columns. These earthquakes also put to the test advanced building technologies that can minimize damage and keep buildings functioning after a quake. Alternatively, seismic dampers, installed in each story of a building, absorb earthquake energy the way shock absorbers work in a car and convert it into heat energy to [minimize damage](https://buildcivil.wordpress.com/2013/11/25/passive-energy-dissipation-devices/). This system allowed the building to stay up and running after the earthquake. [Traditional approaches](https://permanent.fdlp.gov/gpo15358/fema_p_749.pdf) rely on having certain components of the building, like columns or beams, absorb the earthquake’s energy. Designing such buildings will not only save people and buildings but also keep the earthquakes from collapsing communities and economies.
