abstract: In order to research the identification and testing methods of cable force in different
cable structures and meet the test needs of different spatial structures models, a test platform for
general model of building spatial structures is developed, including the main structure with normally
placed quadrangular pyramid bolts grids, reinforcement devices of bidirectional prestressed cables and
displaced monitoring system for platforms. Simulations and analysis on various structures are made with
the help of the finite element software midas Gen, displaying the reasonable-level deformation of the
model test platform, relatively well-proportioned stress distribution as well as satisfactory overall stability.
