This paper is devoted to the issue of post-war reconstruction of damaged buildings and, in particular, panel construction as the most massive in Ukraine. The main structural features of large panel system (LPS) buildings are given and the existing experience of their renovation. Taking into account the state of the industrial base in Ukraine and the impossibility of quick rebuilding of panel houses from the elements of this construction system (precast panels), a new precast-monolithic frame is proposed, which is based on the production of structural elements in a permanent formwork printed using a 3DCP. Basic solutions for columns, beams and slabs have been developed. As an implementation, numerical simulation of a damaged 16-storey panel building with the proposed superstructure system is performed. The obtained results confirmed compliance with all the requirements of regulatory documents for the ULS and SLS limit states and al-lowed the reconstruction of the building to be implemented.
