How it works

Building class. Choose the design class, the number of storeys and the design lateral load coefficient.

Design classes

A design class stands for the seismic design practice of a region and period: the codes, design method and detailing rules that every building of the portfolio is designed with.

Europe

eu_cdn
No CodeBefore 1960
RBA-1935
Allowable stress design for gravity loads only, with no seismic provisions and typically low-strength materials.
eu_cdl
Low Code1960–1970
REBA-1967 (CEB, 1963)
Allowable stress design or stress-block method, with seismic lateral loads proportional to the floor weights.
eu_cdm
Moderate Code1970–2000
REBAP-1983 (CEB-FIP Model Code 1978)
Limit state design with partial safety factors, seismic lateral loads depending on the floor weights and storey heights, and improved detailing for global ductility.
eu_cdh
High Code2000–present
EN 1992-1-1:2004 · EN 1998-1:2004
Capacity design and detailing for ductility class medium (DCM), the class most often adopted in Europe.

The codes of each period are taken as representative of European practice at the time.

Türkiye

tr_7599
Low Code1975–1999
TBEC-1975 · TS500-1984
Ultimate strength design without capacity design; the designs are adjusted for the poor construction quality widespread in the period.
tr_0018_dcm
High Code DCM (1st generation)2000–2018
TBEC-1998 · TBEC-2007 · TS500-2000
Ultimate strength design and detailing for moderate ductility level (DCM), without capacity design rules.
tr_0018_dch
High Code DCH (1st generation)2000–2018
TBEC-1998 · TBEC-2007 · TS500-2000
Capacity design and detailing for high ductility level (DCH): strong column–weak beam, and capacity shear design of beams and columns.
tr_post18_dcm
High Code DCM (2nd generation)2018–present
TBEC-2018 · TS500-2000
Ultimate strength design and detailing for moderate ductility level (DCM), without capacity design rules, and with the overstrength factor in the seismic load reduction.
tr_post18_dch
High Code DCH (2nd generation)2018–present
TBEC-2018 · TS500-2000
Capacity design and detailing for high ductility level (DCH), with stricter ductility requirements and the overstrength factor in the seismic load reduction and in shear design.

Where the seismic code and TS500 differ, the seismic code provisions are followed.
