Response of the building 'Mercado Torroja' of Algeciras, under seismic load

摘要

The Market of Algeciras is one of the most singular buildings of the Spanish engineer Eduardo Torroja. The roof of this structure is a spherical shell supported on eight peripheral piles. This building was built in 1933, and it is being restored at the present. This paper studies the behaviour of this structure when an earthquake hits it. The analysis is made using the current techniques of finite elements. Since there was no regulation when the structure was built, the norm NCSE-94 has been used in the analysis.
