After ten-year service time a tension-truss dome was devoted to a series of full-scale tests. Static and dynamic behavior of the tension-truss frame was examined as well as the structural behavior of the partial reinforcement system with hybrid truss elements. The results of the loading test and pretension measurement are reported here as part 1. Characteristic behavior of the tension truss system with pretension effect was observed. The final failure state was brought about by buckling of a compression truss member. Comparison between designed prestress level and measured prestress is also shown.
