Reinforcement of Concrete Components in Existing Building Using Example of Residential and Commercial Building from 1958

A residential and office building in Berlin-Mitte was built in 1958 as a reinforced concrete structure with a cellar, a ground floor, the first through fouth floor, and an attic. Four plans of the previous conversion planning and eight construction plans from 1957 are available as the basis for processing. As a part of the building conversion, a monopitch roof of the attic is removed. Instead, the building will have a 5th floor as a full floor and a new 1st and 2nd floor as a staggered structure. This state of renovation was designed in an existing structural analysis for story loads of 2.75 kN/m², including the allowance of the partition wall.

As a part of the building conversion, a monopitch roof of the attic is removed. Instead, the building will have a 5th floor as a full floor and a new 1st and 2nd floor as a staggered structure. This state of renovation was designed in an existing structural analysis for story loads of 2.75 kN/m², including the allowance of the partition wall.

The objective of this thesis is to design an alternative reconstruction situation on the basis of the actions according to the new DIN 1055‑3.
