The concrete post is reinforced with 4 13 mm diameter steel bars. A temperature change induces a change in stress of 14.295 MPa in the steel bars. Determine the temperature change and the change in stress in the concrete. Square post cross-section measures 180 mm x 180 mm. EST= 200 GPa ECON = 25 GPa; ST=11.70 mm/mm/°C, CON= 9.90 mm/mm/°C ................
