Seismic assessment of existing buildings and structural design of new ones.

We determine the seismic safety of existing buildings by calculation to TBDY 2018 and prepare strengthening designs for those that need it. We design new reinforced concrete, steel and retaining structures to current codes. Our office is in Ankara; we work across Türkiye and internationally.

01 — Services

From assessing an existing building to designing a new one.

Every job is based on real site data and code requirements. Reports and drawings are prepared for approval by the relevant authorities.

Seismic Assessment of Existing Buildings

Survey, material testing and reinforcement detection feed a structural model in which the building's seismic safety is determined to TBDY 2018 Chapter 15. Where it is needed, a strengthening design follows: new shear walls, jacketing, FRP wrapping or steel bracing.

Rapid Visual Screening (FEMA P-154)

Scoring of many buildings in a portfolio, district or campus with the FEMA P-154 method, to decide which ones need a detailed seismic assessment first.

02 — How we work

Working with clients outside Ankara and abroad

  1. 1BriefYou send what you have: architectural drawings, existing structural drawings, location and soil report. We agree the scope together.
  2. 2ScopeScope of work, deliverables and schedule are agreed in writing.
  3. 3Site workWhere the work needs it — surveys, core sampling, reinforcement detection — site visits are arranged.
  4. 4Analysis and designStructural model, analysis and design to the applicable codes.
  5. 5DeliverablesCalculation report, structural drawings and details, and support during construction.
03 — About us

An engineering practice that stands behind its calculations.

USK Mühendislik Mimarlık Müşavirlik Ltd. Şti. (USK Engineering) was founded in 2023 in Ankara. We carry out seismic assessment and strengthening of existing buildings and design new reinforced concrete and steel structures.
