Building (on) shaking ground
Architektur, Hochbau
Eingeladener Vortrag auf dem internationalen Symposium "Skopje Architecture Week", 27.11.2013 - 29.11.2013, veranstaltet vom Forum Skopje, University American College Skopje und der Fakultät für Bildende Künste Tetovo
50 years ago Skopje was hit by a disastrous earthquake. In remembrance of the catastrophe the lecture investigates the significance of shaking and yielding ground for architecture. It addresses five aspects: 1. In the vernacular architecture of regions with high seismic activity (such as the Indonesian archipelago) remarkable earthquake design strategies have been developed. “Primitive” constructions for decoupling the buildings from their substructures (e.g. flexible fibre pads, bearings with curved surfaces) draw on the same principles of seismic base isolation as contemporary high-tech solutions (e.g. lead-rubber bearings, spherical sliding isolation). 2. Even less violent movements of the ground compromise the stability of buildings. The instable subsoil of the Venetian lagoon called for specific foundations, bracing techniques and waterproofing. In dealing with the yielding ground and uneven settlements the Venetians benefitted from their long shipbuilding experience. They developed elastic constructions that allowed for deformations without damaging the structures and delicate surfaces. 3. When Carlo Scarpa restored the Palazzo Querini Stampalia in Campo Santa Maria Formosa and created an exhibition space on the regularly flooded ground floor he used this intervention to reflect and illustrate the conditions of building in the lagoon. He integrated the “acqua alta” into the palace’s interior and made the dialogue of precious architecture and poor ground a central motif. 4. Trembling or yielding ground is a recurring theme in cemetery architecture and churches of Sigurd Lewerentz’ late work period. The slightly wobbling wooden floor in the Chapels of St. Gertrud and St. Knut (Eastern Cemetery, Malmoe), the kinked lamps and sagging edges of the pond and terrace of Markuskyrkan (Björkhagen, Stockholm) and the brick floor that bursts open to form the baptismal font in St. Petri Church, Klippan are elements of a harsh, yet frail architecture that brings the fragility of life to mind. 5. Vibration also holds an aspect of music. If you step on the small cantilevering concrete stairs linking two levels of Scarpa’s Cemetery Brion (San Vito di Altivole, Italy) they vibrate and produce a chord. This piece of playful architecture closes the lecture’s circle.
