Seismic design of reinforced concrete primary beams to Eurocode 8

 

This is a spreadsheet for the seismic design of primary reinforced concrete beams to EN1998-1

It performs the following resistance and ductility verifications:
5.4.1.2.1(2) Maximum beam eccentricity
5.4.1.2.1(3) Maximum beam width
5.4.3.1.1(1) Resistance in bending and shear
5.4.3.1.1(3) Effective flange width beff
5.4.3.1.2(1) Length of critical zones lcr
5.4.3.1.2(3) Curvature ductility factor – Cl. 5.2.3.4(3)
5.4.3.1.2(4) a) Minimum reinforcement at the compression zone
5.4.3.1.2(4) b) Maximum reinforcement ratio of the tension zone
5.4.3.1.2(5) Minimum reinforcement ratio of the tension zone
5.4.3.1.2(6) a) Minimum diameter of hoops within the critical regions
5.4.3.1.2(6) b) Maximum spacing of hoops within the critical regions
5.6.2.2(2) Anchorage of beam reinforcement – maximum bar diameter
