Stress Analysis and Structural Optimization of Steel–Concrete Joint of Zhonghua Road Bridge in Liaocheng

Table 6

Stress of concrete filled in the joint under different load combinations.

Load	Maximum tensile stress along the bridge’s central line (MPa)	Maximum compressive stress along the bridge’s central line (MPa)	Maximum tensile stress perpendicular to the bridge’s central line (MPa)	Maximum compressive stress perpendicular to the bridge’s central line (MPa)	Maximum principal stress (MPa)
Load 1	2.39	−2.12	2.05	−14.61	2.02/−15.30
Load 2	2.30	−2.26	2.62	−16.62	2.59/−17.54
Load 3	2.40	−2.12	2.06	−14.63	2.03/−15.32
Load 4	1.99	−2.18	2.10	−15.00	2.07/−15.72
Load 5	2.40	−2.13	2.07	−14.72	2.02/−15.42
Load 6	2.52	−2.20	2.19	−15.52	2.51/−16.40

Note: Maximum tensile stress is positive, while maximum compressive stress is negative.
