Ultimate limit state
These parameters influence the Ultimate Limit State requirements stated in ČSN 73 1201-86.
|
Gamma b |
Safety factor for concrete. ČSN 73 1201-86, Art. 2.3 Default value = 1 See chapter Gamma b |
|
Gamma s |
Safety factor for steel. ČSN 73 1201-86, Art. 2.3 Default value = 1 See chapter Gamma s |
|
Max. compression strain of concrete |
Value of limit compression strain of concrete under compression according to the stress-strain diagram. ČSN 73 11201-86, Art. 2.1.4 Default value = -0.0025 |
|
Max. tension strain of steel |
Value of limit tension strain of reinforcement steel according to the stress-strain diagram. ČSN 73 11201-86, Art. 2.2.2.3 Default value = -0.0015 |
Percentage of reinforcement
|
Min. and max. degree to code |
If ON, the minimal percentage of reinforcement for tension and compression reinforcement is determined to the standard. ČSN 73 1201-86, Art. 3.1.4.3 |
|
Min. degree of tension reinforcement |
If option Min. and max. degree to code is OFF, the user specifies the minimal percentage of reinforcement. |
|
Min. degree of compression reinforcement |
If option Min. and max. degree to code is OFF, the user specifies the minimal percentage of reinforcement. |
|
Max. degree in one zone |
The value of maximal percentage of reinforcement for reinforcement located in one zone. ČSN 73 1201-86, Art. 3.1.4.6 Default value = 3 % |
|
Max. degree in two zones, compression - tension |
The value of maximal percentage of reinforcement for reinforcement located in two zones. One zone is under compression, the other one is under tension. ČSN 73 1201-86, Art. 3.1.4.6 Default value = 4 % |
|
Max. degree in two zones, tension - tension |
The value of maximal percentage of reinforcement for reinforcement located in two zones. ČSN 73 1201-86, Art. 3.1.4.6 Default value = 6 % |
Min. percentage of reinforcement – 2D structures
The parameters of this group apply specially to 2D structures – additionally to the parameters of the preceding table, which are common both to 1D and 2D structures.
