    A 3D Kinematic Model for Assessing the Seismic Capacity of the Frigidarium of the Baths of Diocletian
    (IEEE, 2015) Sadholz, Aaron; Muir, Christopher; Perucchio, Renato; Gabriele Guidi and Roberto Scopigno and Juan Barceló
    The Frigidarium of the Baths of Diocletian in Rome is one of the largest extant heritage structures built with unreinforced masonry material. The structural capacity of the Frigidarium to resist lateral accelerations generated by an earthquake is assessed by pushover analysis based on a limit kinematic approach. A 3D solid model of the Frigidarium modular section is subdivided into rigid blocks by cutting planes corresponding to the fracture surfaces determined by a preliminary nonlinear FE analysis. The blocks are then connected by rotational hinges to form a mechanism anchored to a base platform that translates horizontally with increasing acceleration. The mechanism, initially in static equilibrium, is eventually driven into dynamic conditions by the inertial forces generated by the moving platform. The intensity of the acceleration at the limit of the static condition (i.e., at the moment of impending motion) defines the structural capacity. A series of tests is conducted to evaluate the sensitivity of the model to changes in fracture orientation and hinge location, and to the introduction of friction between two blocks. Based on the current results, the capacity can be assessed at about 0.4g.

    A Realistic Gamification Attempt for the Ancient Agora of Athens
    (IEEE, 2015) Kontogianni, Georgia; Georgopoulos, Andreas; Gabriele Guidi and Roberto Scopigno and Pere Brunet
    Digital technologies have affected significantly many fields of computer graphics such as Serious Games. These games are used for educational proposes in many scientific areas one of which is Digital Cultural Heritage. 3D textured models may be a useful tool for developing Serious Games in this field. In this paper a first attempt of creating a Serious Game for the Ancient Agora of Athens is presented. The scope of this game is to help people who are not experts such as school pupils, college students, tourists, museum visitors etc. to gain simple knowledge about the Agora and its monuments. Unity 3D software was used for the game development in which different kinds of realistic photogrammetric data were used. The scenario of the game includes virtual tours of the area in different eras and a simple quiz game. In this quiz game there are questions with three possible answers of which the user is expected to select the right one. In case of a correct answer the game continues to the next question. If the answer is wrong the user is presented with the correct answer and an explanation for his error. The game scenario will include more options in order to make the game more attractive for the player.
