Reinforced Concrete Wall

The steel plate-concrete structure, with its advantages of modular construction, good seismic capacity, and strong impact resistance, has been gradually replacing the reinforced concrete structure in the containment vessel and internal workshop structure of nuclear power plants in recent years. In this study, the out-of-plane single-point loading test and parametric finite element simulation analysis were conducted on five steel plate-concrete wall slab specimens with different stud spacings, shear span ratios, and steel contents. Results showed that the steel plate-concrete wall slab under the out-of-plane load had the same failure mode as that of an ordinary reinforced concrete wall. The out-of-plane shear capacity of the steel plate-concrete wall slab increased significantly in the case of numerous studs. With the increase in shear span ratio, steel plate-concrete members suffered a bending failure. When the steel content was low, they had diagonal tension failure, such as a rare-reinforced concrete wall. The out-of-plane bending and shear mechanism of the steel plate-concrete shear wall was studied theoretically, and the calculation formulas of the bending and shearing capacities were derived.

In recent years, full-scale specimens for seismic test were important to safety assessment of the structure in nuclear power plants but the full-scale tests were not easy to realize due to the limited capable of the existing shaking table capacity. In Taiwan, it was first time to construct a 1/25 scale-down reinforced concrete reactor building specimen in a nuclear power plant and conduct to study the dynamic properties using shaking table test. The specimen was with a length of 2.9 m, width of 2.9 m, height of 2.9 m and weight of 28 tons and cast using the non-demoulding technology and self-consolidating concrete. The entirety structure was composed of a primary containment (thickness of 10 cm), a secondary containment (thickness of 7.5 cm) and three floors (thickness of 30 and 15 cm). The comparison of measured and calculated results demonstrate that ETABS numerical model was satisfactory and can be further used for numerical shaking table tests and real life structures.
