Feature tested

Rebar in substructures.

Problem description

Generation files psupreb1_gen1.inp, psupreb2_gen1.inp, psupreb3_gen1.inp, and psupreb4_gen1.inp are made up of single elements, with each element being treated as a substructure for the purposes of this problem. For the hoop tests the *SUBSTRUCTURE LOAD CASE option is used to define a pressure load acting on the surface of the shell, and a uniform pressure is subsequently applied at the usage level by using the *SLOAD option. For the radial rebar tests the *SUBSTRUCTURE LOAD CASE option is used to define a concentrated load, and it is applied at the usage level at the outer edge of the shell by using the *SLOAD option.

Generation files psupreb5_gen1.inp, psupreb6_gen1.inp, psupreb7_gen1.inp, psupreb8_gen1.inp, psupreb10_gen1.inp, psupreb11_gen1.inp, psupreb12_gen1.inp, and psupreb13_gen1.inp are made up of five elements each, all five elements being combined to form a single substructure. In input files psupreb5.inp, psupreb6.inp, psupreb10.inp, and psupreb11.inp the substructure model is subjected to axial tension applied using the *SLOAD option. In input files psupreb7.inp, psupreb8.inp, psupreb12.inp, and psupreb13.inp a two-step loading is applied, with axial tension applied in the first step and a torsional moment in the second. Both loadings are applied by using the *SLOAD option.

Generation files psupreb9_gen1.inp and psupreba_gen1.inp are made up of five elements each, all five elements being combined to form a single substructure. The substructure model is subjected to an axial tension applied by using the *SLOAD option.

Results and discussion

The results from the substructure analysis exactly match the results that are obtained when substructures are not used.
