Study on mechanical properties of in-situ printed reinforced concrete wall with core column

Abstract

With the lack of manpower, the development of intelligent automation and the promotion of the concept of green environmental protection, 3D printed concrete technology has become a hot spot in the construction industry. Different from the traditional concrete construction technology, 3D printed concrete components can be printed and manufactured in-situ at the construction site. In order to explore the application possibility of 3D printing technology in in-situ printed components, this paper studies the axial compressive performance of in-situ printed core column reinforced concrete wall. The main research contents are as follows: In this paper, 12 pieces of in-situ printed core-column reinforced concrete walls are designed and produced, and the basic form of in-situ printed core column reinforced concrete walls is elaborated. Influencing factors such as the number of core columns, the stirrup configuration forms of core columns, reinforcement ratio and connection modes of transverse reinforcement are set. Axial compression performance experiment was carried out on the wall specimens to study the failure modes and mechanical performance of the in-situ printed core column wall under the action of axial load.
