Reinforced Concrete Column

• Concrete of all strength classes (C 12/15 to C 90/105) specified by the standard
• Lightweight concrete of the strength classes LC 12/13 to LC 80/88
• Consideration of concrete as pre-cast component
• Modulus of elasticity freely defineable by the user
• Creep effects can be disregarded
• SAS 670 according to ETA 13/0840 as additional option (see Design)

• Hinged column
• Cantilever column
• Freely selectable system and restraints are possible
• Different supporting conditions are available for the cold and the hot design
• Freely selectable number of segments with offsets
• Optional foundation restraint
• Appended hinged column can be added to the system (coupled columns)

• Vertical loads with/without eccentricities applying in both directions at freely selectable points
• Moments about the main axes applying at freely selectable points
• Horizontal loads from uniformly distributed loads, block loads, trapezoidal loads, and concentrated loads
• Self-weight can be considered automatically
• User-defineable action groups with freely selectable gamma and psi values
• Loads can apply simultaneously or alternatively

The limit state design is performed for the persistent and transient design situations, and, if available, also for the accidental and seismic design situations. The stiffnesses are determined in state II calculated in a second-order analysis. Idealised reinforcement layers or explicitly specified reinforcement patterns are used as a basis. Imperfections are included automatically. All boundary conditions, such as the minimum reinforcement or the necessity of a buckling safety verification, are performed automatically. The influence of creep is considered via an explicit calculation of the creep-bending curve.

The reinforcement dialog automatically suggests a standard-compliant reinforcement arrangement in the cross-section including necessary structural bars and intermediate stirrups (or S-hooks). Optionally, compaction areas can be considered. The user can manually customise these suggestions via control elements and the graphical user interface (GUI). For multi-part columns, the reinforcement layout is shown for each column segment.

Temperature Design B5-HSB

The hot design can be performed using the simplified method in accordance with EN 1992-1-2, Method A, Section 5.3.2 (Formula 5.7). Alternatively, an FE analysis based on a second-order non-linear structural component calculation and on a non-linear temperature-dependent material behaviour is available. The calculation can be performed in different ways. The user can either determine the required reinforcement, check the entered reinforcement, or calculate the fire-resistance duration.

High-Strength Steel B5-SAS (SAS670)

Calculation with high-strength reinforcing steel SAS 670 from the steel mill Stahlwerk Annahütte Max Aicher GmbH & Co. KG in accordance with the general method. The verification of the load-bearing capacity is based on a second-order analysis and the non-linear concrete action curve. Creep can be considered.
