Materials and Standards
This tab allows to input materials and analysis standards for:
- Concrete structures of bridge abutments
- are specified for the analysis of Concrete structures according to . Both default and user-defined values can be adopted.
- Parameter of cross-section determination - this coefficient determines the location of the critical section for the calculation of bending moment within the wall foundation. Default value for concrete and steel-reinforced concrete columns is k = 0, i.e. the critical section is found at an exposed column face. For masonry structures, it is recommended to choose the value of this coefficient equal to 0,25.
Critical section for the maximum bending moment within the wall foundation
- Parameter of wall jump k - this parameter determines whether the load-bearing reinforcement of the wall front jump is verified or not. For jump length x ≤ k*t the reinforcement verification is not performed. When choosing the option "according to standard" the wall short jump parameter is automatically back calculated according to the selected standard for . When choosing the option "input parameter" the value of parameter k is input by the user. The parameter of short jump of wall is considered for the and for the .
Scheme for determining the parameter of short jump of wall
- Masonry structures (defined in the "Masonry Wall" program only)
- (defined in "Slab", "Sheeting Check" and "Anti-Slide Pile" programs)
- Loads and combinations (defined in "Slab" and "Beam" programs only)
- AASHTO - enables the reduction of friction between the soil-soil interface in the wall analysis to the value of:
- SNiP - enables inputting design coefficients in the sense of Russian standards SNiP.
