Abstract
This paper investigated the failure mechanisms of the stone dome constructed in the heritage site at Jerash. Jerash is the remains of a Roman ancient city and is located 48km north from Amman, Jordan. In the heritage site constructed in the middle of second century, the stately agora, colonnaded streets and the building beside them had been constructed. West Bath in Jerash had one main dome and two small domes. Domes were constructed from stones. Main dome and one sub dome were collapsed and the remained small dome inclined and faced to collapse. In this paper, firstly, the structural characteristics of the remained small dome were investigated numerically based on the shape surveying and the structural characteristics of the total structure were studied as well. Then, secondary, assuming uneven settlement of the pier due to soil flowage and foundation cutting, the structural behavior was assessed by FE analysis.
