Reinforced Concrete Structure Design of 18-Story Building

The thesis comprises the design of a reinforced concrete structure of an 18-story office building. This building is a reinforced concrete plate-and-column structure where the wet technology has been utilized. The facility consists of three segments with a varying number of aboveground stories.

The floor slab of a repetitive story was designed. In particular, the influence of the imposed load distribution on the internal forces in the floor slab was analyzed. The design was carried out for bending, punching, cracking and deflection.

As for the reinforcement design in terms of bending, a simple method was used. The foundation slab was designed in a next step. The support analysis was carried out, and the longitudinal reinforcement at the support point was dimensioned utilizing the following three methods: simplified bending method, three-layer method and a calculation in the structural analysis program. Additionally, a cracking analysis was performed along with calculation of the crack width: according to the analytical method and utilizing the program. Afterwards, the results were compared.

The foundation slab was also dimensioned for the punching effect. The reinforcement was shaped on the basis of reinforcement maps generated in RFEM. The column with the highest cross-section forces was designed. The influence of internal forces on second-order effects was also analyzed. The design was carried out as follows: in a traditional way for bending caused by axial force and utilizing a ready-made spreadsheet. Based on the calculations, reinforcement construction drawings of the designed elements were prepared in Allplan 2019, preceded by additional calculations required for the reinforcement construction.
