Test Method

loading beam for applying force, the loading of pulleys balancing mechanism of following the horizontal movements of the point at the loading is suspended. 2.3 Measurement method 1). They are referred to as specimen and specimen in the following. Specimen has tUbe-to-tube the diagonal members @ of tube-to-tube the 1st the allowable compressive strength for loading based on Design Standard for Steel Struc- ture by AIJ(1973) was chosen so that the ultimate strength of the tube-to-tube X-joint is reached before buckling of the diagonal members @ occurs. The physical properties of the materials used are listed in Table 2
