As of the 2015.i version, when the Colombian NSR-10 concrete code is selected, users can define the type of coarse aggregate in accordance with comments C.8.5.1 of NSR-10, Title C. Users can select the origin of the coarse aggregate:
- Igneous origin
- Metamorphic origin
- Sedimentary origin
- Unspecified (average national value)
Depending on the origin of the aggregate, the problem will use a different modulus of elasticity in the analysis. The modules of elasticity that are applied, depending on the origin of the aggregate and upon applying the formulas that appear in comments C.8.5.1 of NSR-10 Title C, are:
- For coarse igneous aggregates:
Ec = 5500 f 'c in MPa - For coarse metamorphic aggregates:
Ec = 4700 f 'c in MPa - For coarse sedimentary aggregates:
Ec = 3600 f 'c in MPa - The average value for all national experimental information, without specifying the type of aggregate:
Ec = 3900 f 'c in MPa
