Timber Roof of Shopping Mall, Italy
In 2018, Alì Supermercati decided to extend the existing regional commercial network with a new shopping mall located in Via Noalese, Treviso, Italy. The project, designed by Studio Signorotto Architettura of Treviso, includes a glued-laminated timber roof which integrates with the area’s existing wood structures characterized by a perfect aesthetic design and quality building material.

Model
Holz Albertani SpA, an Italian leader in the timber construction field, was awarded the construction and structural design contract for the timber roof supported by reinforced concrete columns. The 72,118 ft² area roof includes trusses connected transversely with stabilizing members in two main directions and a glued-laminated timber decking.
Structural Design
The Holz Albertani SpA engineering office completed the structural design while considering the architectural requirements set by Signorotto Architects. The structural analysis software RFEM and the RF-LAMINATE and RF-DYNAM Pro add-on modules were used in the design calculation for the orthotropic roof surface to evaluate the static analysis in combination with dynamic loads. Due to the detailed structural design perfectly harmonized with the architectural requirements, the roof was assembled in a relatively short period of time while keeping construction issues minimal.
The main structure includes trusses with a maximum span of about 66 ft between the supporting columns. The roof set on the main trusses consists of a 3 5⁄32 in. thick glued-laminated timber slab. The timber members are connected along the trusses as well as to the exterior reinforced concrete frame.
The finished structure includes not only high aesthetic and functional quality, but is also designed to meet the current seismic design requirements.

Filter option for the result tables in the design modules
When designing many members in one design case, it is sometimes difficult to recognize the governing designs. To improve the overview and to display the relevant designs in a compact way, you can use the filter options under the result tables. These are included in all design modules of steel, aluminum and timber structures in RFEM and RSTAB.
- General stress analysis
- Graphical and numerical results of stresses and stress ratios fully integrated in RFEM
- Flexible design with different layer compositions
- High efficiency due to few entries required
- Flexibility due to detailed setting options for calculation basis and extent
- Based on the selected material model and the layers contained, a local overall stiffness matrix of the surface in RFEM is generated. The following material models are available:
- Orthotropic
- Isotropic
- User-defined
- Hybrid (for combinations of material models)
- Option to save frequently used layer structures in a database
- Determination of basic, shear and equivalent stresses
- In addition to the basic stresses, the required stresses according to DIN EN 1995-1-1 and the interaction of those stresses are available as results.
- Stress analysis for structural parts of almost any shape
- Equivalent stresses calculated according to different approaches:
- Shape modification hypothesis (von Mises)
- Maximum shear stress criterion (Tresca)
- Maximum principal stress criterion (Rankine)
- Principal strain criterion (Bach)
- Calculation of transversal shear stresses according to Mindlin, Kirchhoff, or user-defined specifications
- Serviceability limit state design by checking surface displacements
- User-defined specifications of limit deflections
- Possibility to consider layer coupling
- Detailed results of individual stress components and ratios in tables and graphics
- Results of stresses for each layer in the model
- Parts list of designed surfaces
- Possible coupling of layers entirely without shear
- In RF-/TIMBER AWC and RF-/TIMBER CSA, I receive the error that says torsion limit exceeded. How do I bypass this error message?
- Can I consider a reduction of the stiffness according to the German regulation NCI NA.5.9 in TIMBER Pro?
- Why is the strength always reduced by the kmod value of 0.6 during the calculation in the RF‑LAMINATE add‑on module, although I have load combinations with variable loads?
- I have selected all available members for design in RF-/TIMBER Pro. Why are tapered members not designed?
- When performing the fire resistance design with TIMBER Pro, I get the error 10001. How can I fix the error?
- Is it possible to set user-defined values when viewing solid stress results?
- How are the signs for the release results of a line release and line hinges interpreted?
- How can I create a curved or arched section?
- Is it possible to design the support pressure or the compression perpendicular to the grain in RX‑TIMBER?
- After the design with RF‑/TIMBER Pro, I optimized a cross-section. Why is the utilization of the optimized cross-section exceeded now?
