In the seismic design of general buildings, plastic deformations in some parts of the structures are permitted to absorb the energy of large earthquakes As there are many members with a slender ratio over 100 in the steel truss structures, the buckling of these members easily occurs After the occurrence of buckling, the mechanical properties of the steel members would not be ductile For this reason, it is quite difficult to perform the seismic design by permitting the plastic deformation of the steel truss structures In this paper, by using special pipes with another pipe inside for compressive members of truss structures, it is possible to protect buckling and enlarge the abilities for the resistance against loading forces and deformation capability iThree experiments for about one twentieth scale model of the steel six grids planner truss structures, namely, (a) normal truss structure, (b)truss structure with the non-buckling member in the center of upper chords and (c) truss structure using the non-buckling members for all upper chords, were performed to investigate the mechanical properties of the structures The loading was performed by rotating the warm-gear by using stepping motor through the round steel bar attached to, the nodal point on the lower chord members Five loading systems were controlled simultaneously by personal computer It was found out that the improvements for the force-deflection relationship were showed with protecting the buckling of the members Numerical analysis for these specimens were also performed and the results could explain the mechanical behaviour of experiments
