LS-DYNA Simulation of the collapse of Takiyya al Sulaymaniyya under earthquake actions

LS-DYNA Simulation of the collapse of Takiyya al Sulaymaniyya under earthquake actions Takiyya al-Sulaymaniyya is a complex in Damascus, Syria, considered as the most important Ottoman cultural building in the city. It was build by the Sultan Süleyman I or Sulayman al-Qanuni (1520-1566) between 1554 and 1560. The major complex is located on the bank of Barada River. It was built on the ruins of Mamluk sultan Baybars palace “Qasr al-Ablaq” which was destroyed by Tamerlane. The same stones of “Qasr al-Ablaq” have been used to build Takiyya.
Takiyya was designed by Sinan and supervised by architects sent from the imperial architectural office and finished during the period of city’s governor Kheder pasha 1559. In 1566, a Madrasa has been added to the southeast of this complex by Sultan Selim II and linked to them with an Arasta (Souk).
The mosque is the largest and the major part of the complex, located on the southern end of the courtyard. The architecture of the mosque is similar to the prototypical forms used by Sinan a cubic mass crowned by a vast hemispherical dome rising over pendentives, with a portico in front and twin minarets.
The construction of the geometry of the mosque of Takiyya al-Sulaymaniyya is based on the drawings used for retrofitting process in 1960s which are achieved by Directorate General of Antiquities and Museums in Damascus.
The micro modelling strategy has been followed in the construction of the geometry. The whole building was modelled stone by stone. The stone cuts have been considered through modelling.
The collapse simulation under earthquake loads has been done in LS-DYNA.
Constant stress eight-nodded brick element with a single integration point has been employed with a Flangan-Belytschko stiffness form to control the hourglass effect. Tiebreak contact model is employed to represent the interface between the units. The total model includes 768887 nodes and 363567 elements. Each calculation is performed using parallel 40 Intel Itanium processors “SGI Altix 4700” in the centre of High Performance Computing of TU-Dresden.
