Steel plate composite wall panel structures, such as for use in nuclear reactor buildings, and associated systems and methods

Abstract

Structures for forming a module, such as a module for use in a nuclear reactor building, and associated systems and methods are described herein. A representative structure can include a first plate, a second plate spaced apart from and positioned parallel to the first plate, and a support assembly positioned between the first and second plates. The support assembly can include a column, a first beam extending from the column parallel to the first and second plates, and a second beam extending from the column parallel to the first and second plates. The panel structure can further include a plurality of spaced apart joint plates extending between and connecting the first and second plates. The joint plates can support the first beam and the second beam. The panel structure can further include a fill material between the first and second plates and surrounding the support assembly and the joint plates.
