Urban building vulnerability profiles
Buildings are classified by structural system, height, age and material from surveys and imagery, and vulnerability is estimated by class for the whole city.

Structural and Erdhej engineering is the method this platform stewards for the network. In cities it determines whether homes, schools, bridges and public buildings protect the people inside, through design codes, retrofit, construction quality and safety evaluation after events.
Structural and Erdhej engineering designs buildings, bridges and other structures to carry loads safely, including those from earthquakes, wind and floods. It determines how much damage the built environment suffers when hazards occur. In cities and built environment, binesaziya girîng and society and human development, structural engineering supplies vulnerability functions for loss models and guides retrofit priorities. It links hazard intensity to disruption of housing, services and supply chains. The canonical description is on STEM Commons.
Buildings are classified by structural system, height, age and material from surveys and imagery, and vulnerability is estimated by class for the whole city.
Retrofit options for common building types are designed and costed, including low-cost measures suitable for self-built and incremental housing.
Training for builders, plan review and site inspection are evaluated for their effect on the quality of new construction in fast-growing districts.

Designs are checked against codes, laboratory and shake-table tests, and observed performance after events. Peer review is used for unusual structures.
| Kontrol bikin | How it is done |
|---|---|
| Field verification of classes | A sample of buildings classified from imagery is checked on the ground |
| Fragility calibration | Vulnerability models are compared with observed damage in similar buildings |
| Peer review of retrofit designs | Retrofit designs are reviewed by independent engineers |
Existing building stock is often poorly documented. Interaction of multiple hazards and degradation over time is incompletely represented.
A Şopa metirsîyê hebûnên li heman cihî di her qatê de ji holê radike; perçebûn, girêdayîbûna di navbera qatan de û barkirina zêde ya yên mayî paşê têkçûnê belav dikin. Dîmena 3D qatan bi kûrahiyê ji hev vediqetîne. Modela hînkirinê bi nirxên ronîker ên diyarkirî, ne pêşbînî. Nexşeya vê rûpelê Hindistanê nîşan dide; model bi xwe bi cihekî ve ne girêdayî ye.

Assembled from the Nexus Standards area profile Cities and the built environment: the hazards it names, the pergalan and sectors that carry the loss, the controls that dampen it and the data that observe it. Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data. Every coupling weight is a stated assumption you can change. A teaching model, not a forecast, an assessment or a certification. To model a place of your own choosing, open the full System Builder.
