A DEMOUNTABLE PRECAST REINFORCED CONCRETE BUILDING SYSTEM OF MULTI-STORY BUILDINGS

The demountable precast reinforced concrete building system consists of bar and thin-walled units allowing designing hybrid integrated systems of multi-storey buildings. The system's characteristic property are demountable, self-rectifiable and dry joints enabling assembly without wet processes and, in case of need, the disassembly and relocation of the structure. The system applies special mounting, the joint of prestressed hollow core floor units and the load-bearing structure by steel pins additionally embedded in the hollow cores. The article presents the results of experimental research into the major parts and joints of the load-bearing system and the verification of the load-bearing system's prototype exposed to static load tests with an example of the load-bearing system's assembly and disassembly.
