Test database for bearing capacity of circular concrete-filled steel tube (CFST) under axial compression, eccentric compression, and pure bending stress states

The constitutive relations and failure criterion were developed for
circular concrete-filled steel tube (CFST) with high precision and wide
applicability based on the fiber model method to overcome the limitations
of existing constitutive relations and failure criteria for circular CFST
flexural members. Then, on the basis of the test database including the
parameters of circular CFST such as "length",
"Diameter", "Thickness", "Yield strength",
and "Compressive strength", the bearing capacity was calculated
by the fiber model method. Finally, the accuracy and validity of the
proposed constitutive relations and failure criterion were verified by
comparing the calculated values with the "Test values" of the
test database. The test database consists of three tables. Table 1 is the
axial compression test database, containing a total of 516 data sets.
Table 2 is the pure bending test database, comprising 121 data sets.
Lastly, Table 3 is the flexural compression test database, encompassing
365 data sets.
