Membrane Roof Structure on the Banks of the Elbe in Dresden, Germany
Every summer, movie nights and other events take place on the banks of the Elbe in Dresden. Over 200 000 visitors throughout the summer attend more than 55 films and concerts complete with national and international artists.

The membrane roof structure for this seating area was completed before the start of the 2019 summer season. 3dtex and the architect Robert Kerbl, who designed the previous roof 20 years ago, developed the new structure. Similar to the previous design, the roof was considerably increased in size for the increased number of visitors. The structural analysis was completed by zapf & co. from Strausberg utilizing RSTAB.
The new membrane roof structure has a total area of 12,917 ft². The nine main curved trusses spaced at 20 ft on-center are made of glued laminated timber. They are supported on V-shaped steel tube columns.
The coupling and compression members for the longitudinal bracing are also steel pipes. The tension cables are round Rd 16 sections. The structure is covered with a fabric membrane on the upper side of the glued laminated timber truss.

Knowledge Base Articles
The classification of cross-sections according to EN 1993-1-1 and EN 1993-1-5 can be carried out automatically in the RF-/STEEL EC3 add-on module. The maximum c/t ratios are specified in the standard for straight cross -section parts. There are no normative specifications for curved cross -section parts and therefore the cross -section classification cannot be performed for these cross -section parts.

SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.

Frequently Asked Questions (FAQ)
- Is it possible to calculate and design "temporary structures"? What do I need for this?
- How can I create a twisted beam in RFEM?
- How can I perform the design of the tension resistance of a smooth column in a smooth bucket column base, that is, the design against pulling out the column?
- I have already divided my membrane roof into individual surfaces. Can I quickly create a cutting pattern from these surfaces?
- How is an inflatable object simulated in RFEM?
- I design timber components. The deformations of load combinations deviate from the manual calculation exactly by the factor of the material partial safety factor. Why?
- How can I define a material allowance at the edge of a cutting pattern?
- In the RF‑/STEEL EC3 add-on module, I obtain an extremely high design ratio for a member in the case of "Biaxial bending, shear and axial force." Although the axial force is relatively high, the design ratio seems to be unrealistic. What is the reason?
- For which programs is the STEEL Warping Torsion add-on module available?
- I have modeled a structure made of outer and inner cables as well as membranes, and get a message about instability or the error message "Jacobi matrix is not positive definite" in the RF‑FORM‑FINDING add-on module. What should I do?
