Experimental Verification of Demountable Precast Column System

Abstract

Relocation of existing concrete structures requires full or partial demolition, which consumes a lot of energy and thus has a negative impact on the environment. From environmental point of view, demountable precast structures are sustainable. They allow “recycling” to the level of precast elements and so they save significant amounts of energy and materials. Another advantage of these structures is quick assembly without wet processes. A characteristic component of precast reinforced concrete construction system for multi-storey buildings are demountable joints of load-bearing precast reinforced concrete elements. This paper is focused on experimental verification of demountable precast column structure and its demountable steel joints. The experimental research was carried out within TA02010837 “Multipurpose dismantleable prefabricated reinforced concrete building system with controlled joint properties and possibility of repeated use”.
