Variant of assignment for course project No. 355

1. Design Task:

It is required to develop a design of reinforced concrete structures of a multi-storey building with an incomplete frame and prefabricated monolithic floors, to perform calculations of a pre-stressed slab, a multi-span continuous monolithic girder, column and foundation; perform working drawings of designed reinforced concrete structures and parts of element conjugation units.
