To advise the designer and to develop feasible solutions out of visions is the permanent challenge. The Ingenieurbüro Nowak for 25 years – has been converting complex industrial, business and residential projects into effective functional buildings using the latest software.

Rainer Nowak Construction Period 01/2017 - 02/2018 Following the rising demand for high-quality residential buildings and offices, the architect developed a complex and modern block of buildings, which is harmonically included in the urban area. The design shows two residential buildings (1 and 2) which are connected. There are 5 apartments in each of them and a building with 5 offices. Residential building No.2 and the office building are standing together on one floor which contains the underground parking and the basement. The parking has fewer walls. Therefore, there is a problem with the 3D-stability of the structure, as the load has to be carried by slim ribs and only some columns. Building 1 without the basement is reachable by the stairs from building 2. A special challenge was to support the two areas with different support stiffness’s to avoid forbidden settlement differences. Furthermore, the basement is completely in groundwater. To reduce the weight the smaller floors on top of the 3 buildings are created by cellular concrete and the roof by timber. The project was checked using a linear and nonlinear analysis for selected load combinations for the nonlinear subsoil without tension. Furthermore, an additional special nonlinear calculation was done for the time-dependent deformation with cracks in the slabs. Residential and Office Building - Lüdinghausen, Germany
