Selected Aspects of the Structural Analysis of the North Dome in the 'Four Domes Pavilion'/ Wybrane Aspekty Analizy Konstrukcyjnej Kopu?y Pó?nocnej W Pawilonie Czterech Kopu?

摘要

The subject of the paper is north dome of the Four Domes Pavilion in Wroclaw, which was erected according to the project by architect Hans Poelzig in 1913. The geometry of the dome (plan, rise, thickness) has an essential influence on the stress distribution in the structure and may be a crucial factor determining the cracking pattern. The results of the study of archival documents and numerical analysis indicate that there is a need for increasing the bearing capacity of the structure. After carrying out 3D FEM analysis, it was decided to apply strengthening technology based on the FRCM system with carbon and P.B.O. fibers on the surface and on the external ring of the dome.
