Abstract  

The stress redistribution rules of the steel plates and concrete in steel-concrete-steel (SCS) elements under axial compression were analyzed based on Poisson’s effect of materials in order to analyze the composite effect between the steel and concrete in SCS structures under axial compression for nuclear power plants. Two kinds of stress states of the steel plates and concrete, and the lateral constraint stresses of concrete were found from the composite effect. Then the axial compression test results of SCS element were used to demonstrate the theoretical analysis. Results show that the stress redistribution rules of the steel plates and concrete depend on the relative change of the Poisson’s ratio of the two materials. The steel plates are in compression-tension plane stress state and the concrete is in triaxial compression stress state in the limit state of bearing capacity when the SCS element is under axial compression. The " confinement strengthening effect” of concrete is found in SCS element subjected to axial compression.

Key words： steel-concrete-steel (SCS) element      axial compression      Poisson’s effect      composite effect      confinement strengthening effect

核电用双钢板-混凝土单元轴心受压组合效应

为了研究核电用双钢板-混凝土（SCS）结构在轴压荷载作用下钢与混凝土的组合效应，从材料泊松效应的角度出发，分析双钢板-混凝土单元中钢板与混凝土的应力重分布规律，总结钢混组合效应下的2类应力状态和混凝土受侧向约束的特点，采用轴压试验进行论证. 研究表明：钢板与混凝土的应力重分布规律取决于2种材料泊松比的相对变化，对于单轴受压的SCS单元，在达到承载力极限状态时，钢板处于平面压-拉应力状态，混凝土处于三向受压应力状态并存在“约束强化效应”.
