In 1936, a water tower holding 211,000 US gallons was built in Kladno-Rozdělov, Czech Republic. The existing and new supporting steel structures were repurposed as the new administrative building of VKM a.s.

Water Tower Structure
The water tower has a cylindrical shape with a slender lower portion and a wider upper portion where the water tank was previously located. The total height of the water tower is about 135 ft, which includes the 82-foot-tall shaft. Below the tank is an auxiliary floor separating the inner space of the tower into two parts. The basement is located under the tower.
The steel tower’s upper portion consists of eight main columns arranged in a regular 39-foot-diameter octagon, including cross-bracing. In addition, the steel structure incorporates the auxiliary floor beams, a roof, and windows. The steel tank was placed in the area between the columns.
The water tower’s supporting steel structure includes hot-rolled steel sections. The structure shaft consists of eight main columns arranged in a regular 34-foot-diameter octagon with lateral cross-bracing members. In the center, there is a steel staircase with main and quarter landings.
The steel tower’s upper portion consists of eight main columns arranged in a regular 39-foot-diameter octagon, including cross-bracing. In addition, the steel structure incorporates the auxiliary floor beams, a roof, and windows. The steel tank was placed in the area between the columns.
Description of the Renovation
The existing eight main steel columns were preserved, including the ground to 4th floor intermediate diagonal bracing. All existing steel elements from the 4th floor and above were removed.
New columns were added above the existing columns from the 4th floor to the roof elevation. Between the 4th and 5th floors, the columns slope outward from the center, while the columns from the 5th floor up to the roof level are vertical.
The remaining existing structure is complemented by a communication center in the shaft space consisting of eight columns connected by horizontal and diagonal bracing. The communication center has a rectangular floor plan (17.3 ft x 9.1 ft) running from the basement up to the bottom of the 6th floor (the viewing platform).
Two new full floors (the 2nd and 3rd floors) were created inside the tower shaft. Above the shaft in the former building’s tank area, two full floors (the 4th and 5th floors) and one partial floor (the 6th floor) were added.
The horizontal floors from the 2nd floor and up act as rigid frames fixed to the core and the main columns. The individual floors have a circular shape, including the 36-foot-diameter shaft floors and 48-foot-diameter former tank floors.
The top (6th) floor includes recessed windowsills with panoramic windows covered by a conical roof with a skylight. The roof’s supporting structure and skylight consist of symmetrical radial rafters and circumferential steel beams.

Shear Area Types and Their Meanings
Cross-section properties in RFEM and RSTAB include different types of shear areas. This technical article explains the calculation and meaning of various values.

Switching Automatically from Equivalent Member Method to General Method for Stability Analysis in RF-/STEEL EC3
General Method for Stability Analyses According to EN 1993-1-1 and Buckling in Main Load-Bearing Plane
Manual Adjustment of Buckling Curve According to EN 1993-1-1
New
- The design of the connection components is performed according to Eurocode EN 1993-1-8
- After activating the Add-on, the design situations for Steel Connections must be activated in the "Load cases and Combinations" dialog box
- For the design of the connection stability (Buckling), it is necessary to have the Add-on Structure Stability activated
- The calculation can be started via the table or via the icon in the top bar
- I do not want to design a cross-section in the RF‑/STEEL EC3 add-on module. Can I quickly remove this cross-section from the selection?
- Are the models and presentations from Info Day 2018 freely available, and can you send them to me?
- I am designing a set of members using the equivalent member method in RF‑/STEEL EC3, but the calculation fails. The system is unstable, delivering the message "Non-designable - ER055) Zero value of the critical moment on the segment".What could be the reason?
- I am designing a cross-section created in the SHAPE‑THIN program using the design add-on module, but the program shows the error message "ER006 Invalid type of c/t-part for cross-section of type General". What can I do?
- Why are some load cases displayed in red in RF‑STEEL EC3?
- Why are the equivalent member designs grayed out in the Stability tab when activating the plastic designs using the partial internal force method (RF‑/STEEL Plasticity)?
- Is it possible to transfer properties, such as the cross-section, or the surface thickness as well as the material of a surface, of an existing element to a new element?
- How can I create a curved or arched section?
- I would like to calculate and design "flying structures." What do I need for this?
- Which Dlubal Software programs are required to calculate membrane and tensile structures?
