The object’s geometry is captured as a collection of points which is called a “point cloud”. The research team used this technology and conducted an extensive laser scanning of three major historic monuments in Shakhrisabz, Uzbekistan. The city is located in southern Uzbekistan approximately 80 km south of Samarkand, Uzbekistan. Once a major city of Central Asia, it is primarily known today as the birthplace of 14th century Turco-Mongol conqueror Timur. The scanned monuments are from the Timurid Dynasty era and they are on the UNESCO World Heritage List. The Timur's Summer Palace, the Ak-Saray Palace (White Palace) was planned as the most grand of all Timur's constructions and it was started in 1380. Unfortunately, only traces of its gigantic 65 m gate-towers survived. The Kok Gumbaz (Blue Dome) Mosque was built in 1437 and underwent several restorations and reinforcement efforts. East of the Kok Gumbaz, there is another mausoleum complex called Dorus-Saodat (Seat of Power and Might), which contains the Tomb of Jehangir, Timur’s eldest and favorite son. A detailed finite element model of each monument was generated from the as-found geometry captured by laser scans. To monitor the buildings’ possible settlement due to poor soil conditions, special highresolution laser targets were permanently installed. The physical properties of the monuments were investigated by material tests of the major components recovered from the historic sites. The calibrated models were used for comprehensive seismic analysis of the monuments and its components. All current reinforcement details were accounted for in the numerical models. Based on the results of numerical simulations, recommendations on further reinforcement of the historic monuments were developed.
