Capacity Checks (NTC-18)

All the member checks (chord rotation capacity and shear capacity) should be carried out for all the elements of every floor, according to section 4.1.2.3.5 of NTC-18 and section C8.7.2.3 of the commentary, considering the members as primary or secondary (section 7.2.3 of NTC-18) seismic elements. Moreover, beam-column joints checks may be employed in order to check (i) the joint’s diagonal tension and (ii) the joint’s diagonal compression. Finally, interstorey drift checks may be carried out, when needed, for the vertical elements of every floor, according to section 7.3.6.1 of NTC-18.

In SeismoBuild the capacity checks available are the following:

• Deformation Capacity

• Bending Moment Capacity

• Shear Capacity

• Steel Braces Axial Deformations

• Steel Braces Axial Forces

• Joints Diagonal Tension

• Joints Diagonal Compression

• Joints Ductility

• Interstorey Drifts

• Footing Bearing Capacity

• Footings Sliding Forces

• Footings Bending Capacity

• Footings Shear Capacity

• Footings Punching Capacity

• Footings Eccentricity
