The Sassnitz Pedestrian Bridge is located on the island of 📍 Rügen, Germany. Completed in 2007, the one-sided, curved #suspensionbridge provides a connection between the upper city of Sassnitz and the city harbor, overcoming the large height difference of almost 22 meters in an accessible manner. The bridge's beauty lies in its one-sided suspended circular ring girder with eccentrically arranged suspension cables. Instead of being anchored directly to the superstructure, the cables extend outward from the deck via lateral cantilevers, allowing the cable axes to pass exactly through the center of gravity of the cross-section. This design reduces structural stress and allows for an extremely slender superstructure. As a result, the bridge is a lightweight structure that provides an unobstructed view of the sea and harbor.

The Arena da Amazônia in 📍Manaus, Brazil, was built for the 2014 World Cup and hosted a number of matches, including the 2016 Olympic Games. Its special feature is the steel structure with diagonal cantilevered hollow steel box girders. The primary structure includes a compression ring and an outer tension ring supported by spherical bearings.
The stadium's roof and facade are covered with a PTFE-coated fiberglass membrane, providing both durability and aesthetics. The X-shaped box girders along the lateral facade merge seamlessly into the cantilevered roof girders, forming an integral system that enhances the overall design of the building.

The "Signature Bridge" in 📍New Delhi, India connects the city of Wazirabad across the Yamuna River with the city center. The dynamically shaped pylon consists of two inclined pillars, which merge at mid-height. The upper part of the pylon anchors both the back stay cables and the harp-shaped main stay cables. The top of the pylon forms a steel and glass structure that is illuminated at night, turning the bridge into a landmark. The inclined pylon takes the load off the restraining cables by using its own weight on one side of the pylon base to partially compensate for the weight of the superstructure on the other side. The fact that the modules are bolted together on site instead of welded is an adaptation to locally common and practicable construction techniques.

As the A8 motorway between the Stuttgart intersection and the Leonberg/Ost junction was widened by one lane, the existing "Rotes Steigle" arch bridge had to be replaced by a distinctive new structure. As a modern answer to the previous bridge, a filigree steel arch bridge was created. The supporting structure of the integral composite bridge consists of a steel arch at the bottom with a variable cross-section, steel struts inclined obliquely outwards and a reinforced concrete deck slab. The superstructure is supported on the arch by thin, inclined struts and is monolithically connected to the abutments by a steel plate, a so-called "spring lamella". The individual steel components were pre-assembled into two large segments, so that only two full nighttime closures of the highway were required for lifting. The concrete slab was poured under moving traffic.

A structure of wood and glass covers the training academy Mont-Cenis in 📍 Herne, Germany.
The entire academy is surrounded by a 12,000 square meter glass shell. The 180m long and 72m wide structure consists of timber trusses supported on 130-year-old pine logs. The light-flooded interior space created below contains several individual buildings. Since these are protected from all weather conditions, they could be constructed with basic building physics principles.
Already back then, in 1999, we planned a Building Integrated Photovoltaic system together with sbp sonne: The PV modules were installed on the facade and cover an area of around 10,000 square meters. At the time of completion, the solar system integrated into the building was considered one of the largest in the world.

During this year's team trip of our Shanghai office, our colleagues had the opportunity to visit the construction site of the ZFAU University Campus in Hangzhou. The main building has a total length of 400m and a width of 168m and is characterized by its aerodynamically curved roof structure. At its middle section, the building structure gets divided to form a spacious plaza. It is covered by a hanging roof that is anchored to the upper edges of the buildings at the sides. It has a free span of 133m and is supported by stainless steel cables with a distance of 8,40m.

This week, the world-famous Salone del Mobile furniture fair is once again taking place in 📍 Milan, Italy.
Visitors are welcomed by a large, funnel-shaped glass sculpture that simultaneously serves as a canopy connecting the exhibition halls along the main axis. The grids of the double-curved sculpture as well as of the free-formed glass roof consist mainly of square meshes into which diagonal rods were inserted. The biggest challenge in this project was to design a grid that seamlessly transitions from the quadrilateral mesh in the shallow sections to the triangular mesh in the free-formed sections.

The Estádio Maracanã in 📍 Rio de Janeiro, Brazil is probably one of the most famous soccer stadiums in the world. For the 2014 FIFA World Cup, the stadium, which is now more than 20 years old, was completely modernized. Due to its historical and cultural value, the main goal was to treat the building with necessary respect during the design process. To preserve the original appearance, the roof structure had to be kept low at the inner and outer edges and hover barely above the stadium shell. The structural concept is based on the design principle of a spoked wheel with one compression ring and a total of three tension rings. The old cantilever roof was completely replaced by the new, larger roof, which rests on the existing columns of the building. The entire roof is covered with a PTFE-coated fiberglass membrane.

The Chunshengang Bridge in 📍Shanghai, China, is part of a large-scale project to develop and restore a former industrial area.
Numerous streams flow into the Huangpu River and have to be crossed by pedestrians, private traffic and public transport. The three-span truss bridge leads across the estuary of the Huangpu. With four lanes, two pedestrian paths and tracks for the tram, it relieves the traffic on a highly frequented road. The bridge is characterised by its steel structure, consisting of two trusses in the main supporting structure, each reduced to a single section. Positioned inwards in the cross section of the bridge, they separate the various traffic areas.

As one of the largest transportation hubs in Europe, the main station in 📍 Berlin connects all four cardinal directions since 2006. The long station building, which runs east-west, spans six tracks with a maximum length of about 66 meters. The roof of the hall was built before the opening of the new line, while the side buildings and the roof in the north-south direction were erected only after the station started its operations. The east-west roof also has 780 photovoltaic panels integrated into the glazed areas.
