"PANOPLIA preprocessor" is part of a sophisticated software system intended for the design and analysis of earthquake resistant reinforced concrete buildings, called PANOPLIA. Using "PANOPLIA preprocessor" the user has all the appropriate tools to model the building's framework in a rapid and intuitive environment, simultaneous 2D and 3D view, and the means to visualize the resulting building's frame. Since the description of a complicated building is a time consuming and sometimes frustrating procedure, it is quite clear that PANOPLIA preprocessor offers a competitive advantage, due to its intelligent and holistic approach to the description process that treats structural elements as dynamic entities that interact and connect to each other in order to create the uniform frame of the building. The resulting model of the building may be easily exported to a number of appropriate applications for further static and dynamic analysis. This version is capable to export to the following applications: pi-Systems Stereostatika * pi-Systems PANOPLIA * CSI Etabs * CSI SAP2000 * Berkeley Opensees * *All corporate names and trademarks are the property of their respective companies.
