Optimal Design Feature

The optimal design feature of midas Gen optimizes the member sections, which determines the

section dimensions automatically for the minimum sectional area (minimum weights) satisfying

the specified design standard through verifying strength ratio (or stress ratio) in iterative

analysis.

Capacity Design feature

• structures to provide the appropriate amount of ductility in the corresponding ductility classes.

• Automatic capacity design capability for beam, column, wall and beam-column joint • EN 1998-1: 2004 (DCM/DCH) • NTC2008 (CD “B”, CD “A”) • Design action effects are calculated in accordance with the capacity design rule. Special

provision for ductile primary seismic walls is considered. • Detailing for local ductility is considered.

- max/min reinforcement ratio of the tension zone - the spacing of hoops within the critical region - mechanical volumetric ratio of confining hoops with the critical regions
