Los Angeles Football Club Soccer Stadium Aluminum Grandstands, Los Angeles, CA, USA
Customer Project
The removable grandstands are surrounded on three sides by precast seating risers in the north endzone of the Los Angeles Football club soccer stadium. The grandstands are a free-standing system. The system is comprised of aluminum trusses, which are demountable from aluminum towers.

Dimensions of One Grandstand
Model
The clear span between the single towers amounts to approximately 16 ft. The majority of the members are aluminum square and rectangular tubes. The towers are attached to the concrete substrate via internally threaded inserts epoxied into the concrete, resulting in a flush surface when the system is removed.
The design in this area required Trex Commercial Products to provide folding seats and a guard rail to allow for safer spectator standing areas. The folding seats integrate into guard rail units, and these are attached to the front of the aluminum risers.
Design
The primary design challenges were based on the materials used and the use of the structure. The structure was welded aluminum, such that reduced properties had to be considered in the weld zones, which was possible using the ALUMINUM ADM add-on module for RSTAB. DYNAM Pro was utilized to analyze the natural vibration modes and the performance of the structure subjected to significantly demanding rhythmic activities by spectators.

Member Transverse Stiffeners in RFEM 6 and RSTAB 9
This article shows you how to define different types of member transverse stiffeners in RFEM 6 and RSTAB 9. It also shows you how to consider them in the design as well as the calculation of members with 7 degrees of freedom.
The Torsional Warping (7 DOF) add-on allows you to easily perform the calculation of member structures in RFEM and RSTAB, taking into account the cross-section warping.

My beam has a continuous lateral support and therefore lateral torsional buckling (LTB) is not a concern. How do I define the effective length?
- How do I consider the strength of weld-affected zone for aluminum?
- How can I carry out case-related design for different load situations?
