A2.4. Three Dimensional Composite (Steel & Concrete) Structure
Problem Description
A three dimensional composite structure forming an octagon shape and subjected to vertical
loading is examined (Figure A2.4.1).
Geometry, Properties and Loads
The cross section of internal horizontal steel members is IPE-500 (Group A, B) and the
dimensions of horizontal concrete beams’ rectangular cross-section are 30cmx60cm. Every
column (Group C) has a Concrete Circular Cross Section of 60cm diameter with ends fixed
within ground.
All steel beams of Group A forming a square shape are subjected to vertical uniformly
distributed load of 10kN/m. Modulus of elasticity and Poisson ratio of the material for steel
and concrete members are 210GPa, 0.30 and 29GPa, ν=0.20, respectively.
Assumptions
During analysis, shear deformations are neglected. Section properties are recovered from the
cross section library of ScadaPro and are presented in Tables A2.4.1, A2.4.2 and A2.4.3.
