Restoration Plan of Second Gate in Bam Citadel (Arg e Bam)

Abstract eng:
One of the famous monuments in the Bam Citadel that cracked seriously and collapsed more than 10% during the earthquake in 2003; is called Second Gate. This paper tries to explain the full 3-D dynamic analysis relevant to provide the proposed restoration plan of this building. The achieved dynamic analysis of this structure is used the real time histories (recorded from stations in Bam) as earthquake load with respect to the geographical direction of the structure and direction of the earthquake. For proposing an acceptable restoration plan considering authenticity of the monument in one hand, and for stabilizing the structure against further earthquake, such element like bamboo is introduced to the structure as the tensile elements and the dynamic analysis is repeated with respect to the bamboos position in the walls, roofs and domes. The calculation shows reasonable results and confirms the ability of the structure against the further similar earthquakes when bamboo is using as tensile elements.
