Abstrakt: |
Three early reinforced concrete structures of high cultural values located in Switzerland are investigated in view of their future utilization: (1) Schrähbach Bridge, probably the World’s first stiffened arch bridge structure designed and built in 1923 by Robert Maillart, (2) Hauteroche Mansion, a three storey monolithic reinforced concrete building designed and built by François Hennebique in 1913, and (3) Guillermaux Bridge from 1920 which is a flat three hinge arch bridge designed by Louis Bosset. Examination of the actual performance revealed that all three structures can be restored and strengthened to meet the requirements of future modern utilization. While in one case the early RC structure is condemned to be demolished and replaced, a restoration project is in progress for the future utilization of the two other structures. From these three cases it must be concluded that appropriate treatment of and interventions on structures with adequate respect of cultural values depend primarily on the motivation and know-how of the persons involved as well as on the legal and regulative bases. Technical facts and economic evidence are not always sufficient for the preservation of structures of high cultural value. Yet, preservation of cultural values may go hand in hand with socio-economic, environmental and technical requirements. These requirements are often met by the application of advanced structural engineering methods specific to existing structures. |
